The wind, the sun, and Earth are sources of  renewable energy . These energy sources naturally renew, or replenish themselves.

Wind, sunlight, and the planet have energy that transforms in ways we can see and feel. We can see and feel evidence of the transfer of energy from the sun to Earth in the sunlight shining on the ground and the warmth we feel when sunlight shines on our skin. We can see and feel evidence of the transfer of energy in wind’s ability to pull kites higher into the sky and shake the leaves on trees. We can see and feel evidence of the transfer of energy in the geothermal energy of steam vents and geysers .

People have created different ways to capture the energy from these renewable sources.

Solar Energy

Solar energy can be captured “actively” or “passively.”

Active solar energy uses special technology to capture the sun’s rays. The two main types of equipment are photovoltaic cells (also called PV cells or solar cells) and mirrors that focus sunlight in a specific spot. These active solar technologies use sunlight to generate electricity , which we use to power lights, heating systems, computers, and televisions.

Passive solar energy does not use any equipment. Instead, it gets energy from the way sunlight naturally changes throughout the day. For example, people can build houses so their windows face the path of the sun. This means the house will get more heat from the sun. It will take less energy from other sources to heat the house.

Other examples of passive solar technology are green roofs , cool roofs, and radiant barriers . Green roofs are completely covered with plants. Plants can get rid of pollutants in rainwater and air. They help make the local environment cleaner.

Cool roofs are painted white to better reflect sunlight. Radiant barriers are made of a reflective covering, such as aluminum. They both reflect the sun’s heat instead of absorbing it. All these types of roofs help lower the amount of energy needed to cool the building.

Advantages and Disadvantages There are many advantages to using solar energy. PV cells last for a long time, about 20 years.

However, there are reasons why solar power cannot be used as the only power source in a community. It can be expensive to install PV cells or build a building using passive solar technology.

Sunshine can also be hard to predict. It can be blocked by clouds, and the sun doesn’t shine at night. Different parts of Earth receive different amounts of sunlight based on location, the time of year, and the time of day.

Wind Energy

People have been harnessing the wind’s energy for a long, long time. Five-thousand years ago, ancient Egyptians made boats powered by the wind. In 200 B.C.E., people used windmills to grind grain in the Middle East and pump water in China.

Today, we capture the wind’s energy with wind turbines . A turbine is similar to a windmill; it has a very tall tower with two or three propeller-like blades at the top. These blades are turned by the wind. The blades turn a generator (located inside the tower), which creates electricity.

Groups of wind turbines are known as wind farms . Wind farms can be found near farmland, in narrow mountain passes, and even in the ocean, where there are steadier and stronger winds. Wind turbines anchored in the ocean are called “ offshore wind farms.”

Wind farms create electricity for nearby homes, schools, and other buildings.

Advantages and Disadvantages Wind energy can be very efficient . In places like the Midwest in the United States and along coasts, steady winds can provide cheap, reliable electricity.

Another great advantage of wind power is that it is a “clean” form of energy. Wind turbines do not burn fuel or emit any pollutants into the air.

Wind is not always a steady source of energy, however. Wind speed changes constantly, depending on the time of day, weather , and geographic location. Currently, it cannot be used to provide electricity for all our power needs.

Wind turbines can also be dangerous for bats and birds. These animals cannot always judge how fast the blades are moving and crash into them.

Geothermal Energy

Deep beneath the surface is Earth’s core . The center of Earth is extremely hot—thought to be over 6,000 °C (about 10,800 °F). The heat is constantly moving toward the surface.

We can see some of Earth’s heat when it bubbles to the surface. Geothermal energy can melt underground rocks into magma and cause the magma to bubble to the surface as lava . Geothermal energy can also heat underground sources of water and force it to spew out from the surface. This stream of water is called a geyser.

However, most of Earth’s heat stays underground and makes its way out very, very slowly.

We can access underground geothermal heat in different ways. One way of using geothermal energy is with “geothermal heat pumps.” A pipe of water loops between a building and holes dug deep underground. The water is warmed by the geothermal energy underground and brings the warmth aboveground to the building. Geothermal heat pumps can be used to heat houses, sidewalks, and even parking lots.

Another way to use geothermal energy is with steam. In some areas of the world, there is underground steam that naturally rises to the surface. The steam can be piped straight to a power plant. However, in other parts of the world, the ground is dry. Water must be injected underground to create steam. When the steam comes to the surface, it is used to turn a generator and create electricity.

In Iceland, there are large reservoirs of underground water. Almost 90 percent of people in Iceland use geothermal as an energy source to heat their homes and businesses.

Advantages and Disadvantages An advantage of geothermal energy is that it is clean. It does not require any fuel or emit any harmful pollutants into the air.

Geothermal energy is only avaiable in certain parts of the world. Another disadvantage of using geothermal energy is that in areas of the world where there is only dry heat underground, large quantities of freshwater are used to make steam. There may not be a lot of freshwater. People need water for drinking, cooking, and bathing.

Biomass Energy

Biomass is any material that comes from plants or microorganisms that were recently living. Plants create energy from the sun through photosynthesis . This energy is stored in the plants even after they die.

Trees, branches, scraps of bark, and recycled paper are common sources of biomass energy. Manure, garbage, and crops , such as corn, soy, and sugar cane, can also be used as biomass feedstocks .

We get energy from biomass by burning it. Wood chips, manure, and garbage are dried out and compressed into squares called “briquettes.” These briquettes are so dry that they do not absorb water. They can be stored and burned to create heat or generate electricity.

Biomass can also be converted into biofuel . Biofuels are mixed with regular gasoline and can be used to power cars and trucks. Biofuels release less harmful pollutants than pure gasoline.

Advantages and Disadvantages A major advantage of biomass is that it can be stored and then used when it is needed.

Growing crops for biofuels, however, requires large amounts of land and pesticides . Land could be used for food instead of biofuels. Some pesticides could pollute the air and water.

Biomass energy can also be a nonrenewable energy source. Biomass energy relies on biomass feedstocks—plants that are processed and burned to create electricity. Biomass feedstocks can include crops, such as corn or soy, as well as wood. If people do not replant biomass feedstocks as fast as they use them, biomass energy becomes a non-renewable energy source.

Hydroelectric Energy

Hydroelectric energy is made by flowing water. Most hydroelectric power plants are located on large dams , which control the flow of a river.

Dams block the river and create an artificial lake, or reservoir. A controlled amount of water is forced through tunnels in the dam. As water flows through the tunnels, it turns huge turbines and generates electricity.

Advantages and Disadvantages Hydroelectric energy is fairly inexpensive to harness. Dams do not need to be complex, and the resources to build them are not difficult to obtain. Rivers flow all over the world, so the energy source is available to millions of people.

Hydroelectric energy is also fairly reliable. Engineers control the flow of water through the dam, so the flow does not depend on the weather (the way solar and wind energies do).

However, hydroelectric power plants are damaging to the environment. When a river is dammed, it creates a large lake behind the dam. This lake (sometimes called a reservoir) drowns the original river habitat deep underwater. Sometimes, people build dams that can drown entire towns underwater. The people who live in the town or village must move to a new area.

Hydroelectric power plants don’t work for a very long time: Some can only supply power for 20 or 30 years. Silt , or dirt from a riverbed, builds up behind the dam and slows the flow of water.

Other Renewable Energy Sources

Scientists and engineers are constantly working to harness other renewable energy sources. Three of the most promising are tidal energy , wave energy , and algal (or algae) fuel.

Tidal energy harnesses the power of ocean tides to generate electricity. Some tidal energy projects use the moving tides to turn the blades of a turbine. Other projects use small dams to continually fill reservoirs at high tide and slowly release the water (and turn turbines) at low tide.

Wave energy harnesses waves from the ocean, lakes, or rivers. Some wave energy projects use the same equipment that tidal energy projects do—dams and standing turbines. Other wave energy projects float directly on waves. The water’s constant movement over and through these floating pieces of equipment turns turbines and creates electricity.

Algal fuel is a type of biomass energy that uses the unique chemicals in seaweed to create a clean and renewable biofuel. Algal fuel does not need the acres of cropland that other biofuel feedstocks do.

Renewable Nations

These nations (or groups of nations) produce the most energy using renewable resources. Many of them are also the leading producers of nonrenewable energy: China, European Union, United States, Brazil, and Canada

Renewable energy, explained

Solar, wind, hydroelectric, biomass, and geothermal power can provide energy without the planet-warming effects of fossil fuels.

In any discussion about climate change , renewable energy usually tops the list of changes the world can implement to stave off the worst effects of rising temperatures. That's because renewable energy sources such as solar and wind don't emit carbon dioxide and other greenhouse gases that contribute to global warming .

Clean energy has far more to recommend it than just being "green." The growing sector creates jobs , makes electric grids more resilient, expands energy access in developing countries, and helps lower energy bills. All of those factors have contributed to a renewable energy renaissance in recent years, with wind and solar setting new records for electricity generation .

For the past 150 years or so, humans have relied heavily on coal, oil, and other fossil fuels to power everything from light bulbs to cars to factories. Fossil fuels are embedded in nearly everything we do, and as a result, the greenhouse gases released from the burning of those fuels have reached historically high levels .

As greenhouse gases trap heat in the atmosphere that would otherwise escape into space, average temperatures on the surface are rising . Global warming is one symptom of climate change, the term scientists now prefer to describe the complex shifts affecting our planet’s weather and climate systems. Climate change encompasses not only rising average temperatures but also extreme weather events, shifting wildlife populations and habitats, rising seas , and a range of other impacts .

Of course, renewables—like any source of energy—have their own trade-offs and associated debates. One of them centers on the definition of renewable energy. Strictly speaking, renewable energy is just what you might think: perpetually available, or as the U.S. Energy Information Administration puts it, " virtually inexhaustible ." But "renewable" doesn't necessarily mean sustainable, as opponents of corn-based ethanol or large hydropower dams often argue. It also doesn't encompass other low- or zero-emissions resources that have their own advocates, including energy efficiency and nuclear power.

Types of renewable energy sources

Hydropower: For centuries, people have harnessed the energy of river currents, using dams to control water flow. Hydropower is the world's biggest source of renewable energy by far, with China, Brazil, Canada, the U.S., and Russia the leading hydropower producers . While hydropower is theoretically a clean energy source replenished by rain and snow, it also has several drawbacks.

FREE BONUS ISSUE

Large dams can disrupt river ecosystems and surrounding communities , harming wildlife and displacing residents. Hydropower generation is vulnerable to silt buildup, which can compromise capacity and harm equipment. Drought can also cause problems. In the western U.S., carbon dioxide emissions over a 15-year period were 100 megatons higher than they normally would have been, according to a 2018 study , as utilities turned to coal and gas to replace hydropower lost to drought. Even hydropower at full capacity bears its own emissions problems, as decaying organic material in reservoirs releases methane.

Dams aren't the only way to use water for power: Tidal and wave energy projects around the world aim to capture the ocean's natural rhythms. Marine energy projects currently generate an estimated 500 megawatts of power —less than one percent of all renewables—but the potential is far greater. Programs like Scotland’s Saltire Prize have encouraged innovation in this area.

Wind: Harnessing the wind as a source of energy started more than 7,000 years ago . Now, electricity-generating wind turbines are proliferating around the globe, and China, the U.S., and Germany are the leading wind energy producers. From 2001 to 2017 , cumulative wind capacity around the world increased to more than 539,000 megawatts from 23,900 mw—more than 22 fold.

Some people may object to how wind turbines look on the horizon and to how they sound, but wind energy, whose prices are declining , is proving too valuable a resource to deny. While most wind power comes from onshore turbines, offshore projects are appearing too, with the most in the U.K. and Germany. The first U.S. offshore wind farm opened in 2016 in Rhode Island, and other offshore projects are gaining momentum . Another problem with wind turbines is that they’re a danger for birds and bats, killing hundreds of thousands annually , not as many as from glass collisions and other threats like habitat loss and invasive species, but enough that engineers are working on solutions to make them safer for flying wildlife.

Solar: From home rooftops to utility-scale farms, solar power is reshaping energy markets around the world. In the decade from 2007 and 2017 the world's total installed energy capacity from photovoltaic panels increased a whopping 4,300 percent .

In addition to solar panels, which convert the sun's light to electricity, concentrating solar power (CSP) plants use mirrors to concentrate the sun's heat, deriving thermal energy instead. China, Japan, and the U.S. are leading the solar transformation, but solar still has a long way to go, accounting for around two percent of the total electricity generated in the U.S. in 2017. Solar thermal energy is also being used worldwide for hot water, heating, and cooling.

Biomass: Biomass energy includes biofuels such as ethanol and biodiesel , wood and wood waste, biogas from landfills, and municipal solid waste. Like solar power, biomass is a flexible energy source, able to fuel vehicles, heat buildings, and produce electricity. But biomass can raise thorny issues.

Critics of corn-based ethanol , for example, say it competes with the food market for corn and supports the same harmful agricultural practices that have led to toxic algae blooms and other environmental hazards. Similarly, debates have erupted over whether it's a good idea to ship wood pellets from U.S. forests over to Europe so that it can be burned for electricity. Meanwhile, scientists and companies are working on ways to more efficiently convert corn stover , wastewater sludge , and other biomass sources into energy, aiming to extract value from material that would otherwise go to waste.

Geothermal: Used for thousands of years in some countries for cooking and heating, geothermal energy is derived from the Earth’s internal heat . On a large scale, underground reservoirs of steam and hot water can be tapped through wells that can go a mile deep or more to generate electricity. On a smaller scale, some buildings have geothermal heat pumps that use temperature differences several feet below ground for heating and cooling. Unlike solar and wind energy, geothermal energy is always available, but it has side effects that need to be managed, such as the rotten egg smell that can accompany released hydrogen sulfide.

Ways to boost renewable energy

Cities, states, and federal governments around the world are instituting policies aimed at increasing renewable energy. At least 29 U.S. states have set renewable portfolio standards —policies that mandate a certain percentage of energy from renewable sources, More than 100 cities worldwide now boast at least 70 percent renewable energy, and still others are making commitments to reach 100 percent . Other policies that could encourage renewable energy growth include carbon pricing, fuel economy standards, and building efficiency standards. Corporations are making a difference too, purchasing record amounts of renewable power in 2018.

Wonder whether your state could ever be powered by 100 percent renewables? No matter where you live, scientist Mark Jacobson believes it's possible. That vision is laid out here , and while his analysis is not without critics , it punctuates a reality with which the world must now reckon. Even without climate change, fossil fuels are a finite resource, and if we want our lease on the planet to be renewed, our energy will have to be renewable.

What is renewable energy?

Renewable energy is energy derived from natural sources that are replenished at a higher rate than they are consumed. Sunlight and wind, for example, are such sources that are constantly being replenished. Renewable energy sources are plentiful and all around us.

Fossil fuels - coal, oil and gas - on the other hand, are non-renewable resources that take hundreds of millions of years to form. Fossil fuels, when burned to produce energy, cause harmful greenhouse gas emissions, such as carbon dioxide.

Generating renewable energy creates far lower emissions than burning fossil fuels. Transitioning from fossil fuels, which currently account for the lion’s share of emissions, to renewable energy is key to addressing the climate crisis.

Renewables are now cheaper in most countries, and generate three times more jobs than fossil fuels.

Here are a few common sources of renewable energy:

SOLAR ENERGY

Solar energy is the most abundant of all energy resources and can even be harnessed in cloudy weather. The rate at which solar energy is intercepted by the Earth is about 10,000 times greater than the rate at which humankind consumes energy.

Solar technologies can deliver heat, cooling, natural lighting, electricity, and fuels for a host of applications. Solar technologies convert sunlight into electrical energy either through photovoltaic panels or through mirrors that concentrate solar radiation.

Although not all countries are equally endowed with solar energy, a significant contribution to the energy mix from direct solar energy is possible for every country.

The cost of manufacturing solar panels has plummeted dramatically in the last decade, making them not only affordable but often the cheapest form of electricity. Solar panels have a lifespan of roughly 30 years , and come in variety of shades depending on the type of material used in manufacturing.

WIND ENERGY

Wind energy harnesses the kinetic energy of moving air by using large wind turbines located on land (onshore) or in sea- or freshwater (offshore). Wind energy has been used for millennia, but onshore and offshore wind energy technologies have evolved over the last few years to maximize the electricity produced - with taller turbines and larger rotor diameters.

Though average wind speeds vary considerably by location, the world’s technical potential for wind energy exceeds global electricity production, and ample potential exists in most regions of the world to enable significant wind energy deployment.

Many parts of the world have strong wind speeds, but the best locations for generating wind power are sometimes remote ones. Offshore wind power offers t remendous potential .

GEOTHERMAL ENERGY

Geothermal energy utilizes the accessible thermal energy from the Earth’s interior. Heat is extracted from geothermal reservoirs using wells or other means.

Reservoirs that are naturally sufficiently hot and permeable are called hydrothermal reservoirs, whereas reservoirs that are sufficiently hot but that are improved with hydraulic stimulation are called enhanced geothermal systems.

Once at the surface, fluids of various temperatures can be used to generate electricity. The technology for electricity generation from hydrothermal reservoirs is mature and reliable, and has been operating for more than 100 years .

Hydropower harnesses the energy of water moving from higher to lower elevations. It can be generated from reservoirs and rivers. Reservoir hydropower plants rely on stored water in a reservoir, while run-of-river hydropower plants harness energy from the available flow of the river.

Hydropower reservoirs often have multiple uses - providing drinking water, water for irrigation, flood and drought control, navigation services, as well as energy supply.

Hydropower currently is the largest source of renewable energy in the electricity sector. It relies on generally stable rainfall patterns, and can be negatively impacted by climate-induced droughts or changes to ecosystems which impact rainfall patterns.

The infrastructure needed to create hydropower can also impact on ecosystems in adverse ways. For this reason, many consider small-scale hydro a more environmentally-friendly option , and especially suitable for communities in remote locations.

OCEAN ENERGY

Ocean energy derives from technologies that use the kinetic and thermal energy of seawater - waves or currents for instance -  to produce electricity or heat.

Ocean energy systems are still at an early stage of development, with a number of prototype wave and tidal current devices being explored. The theoretical potential for ocean energy easily exceeds present human energy requirements.

Bioenergy is produced from a variety of organic materials, called biomass, such as wood, charcoal, dung and other manures for heat and power production, and agricultural crops for liquid biofuels. Most biomass is used in rural areas for cooking, lighting and space heating, generally by poorer populations in developing countries.

Modern biomass systems include dedicated crops or trees, residues from agriculture and forestry, and various organic waste streams.

Energy created by burning biomass creates greenhouse gas emissions, but at lower levels than burning fossil fuels like coal, oil or gas. However, bioenergy should only be used in limited applications, given potential negative environmental impacts related to large-scale increases in forest and bioenergy plantations, and resulting deforestation and land-use change.

There are several types of renewable energy. Solar energy, obtained from the sun’s radiation, is harnessed using photovoltaic cells. Wind energy, generated by wind turbines, is another significant source. Hydropower, the oldest form of renewable energy, converts the energy produced by flowing or falling water. Additionally, geothermal energy utilizes the Earth’s internal heat, while bioenergy comes from organic materials.

Renewable energy offers numerous benefits. It reduces reliance on fossil fuels, which are finite and environmentally damaging. By switching to renewable sources, we can significantly lower greenhouse gas emissions, mitigating climate change. Additionally, renewable energy sources are often decentralized, promoting energy security and reducing energy poverty.

Challenges and Future Prospects

Despite its benefits, renewable energy faces challenges such as intermittency, high initial costs, and the need for significant land and water resources. However, technological advancements and policy support can overcome these barriers. The future of renewable energy is promising, with the International Energy Agency forecasting that 30% of the world’s energy will come from renewables by 2024.

In conclusion, renewable energy is a viable, sustainable solution to our energy needs, offering a path towards a cleaner, healthier, and more equitable world.

500 Words Essay on Renewable Energy

Renewable energy, an essential part of our global energy future, harnesses naturally occurring and inexhaustible resources such as sunlight, wind, and water. Unlike fossil fuels, which are finite, renewable energy sources regenerate and can be sustained indefinitely.

The Importance of Renewable Energy

The significance of renewable energy extends far beyond its renewability. It plays a crucial role in reducing greenhouse gas emissions. Fossil fuels, when burned for power and heat, emit carbon dioxide, a primary driver of climate change. Renewable energy sources, on the other hand, often generate power without producing greenhouse gases.

Moreover, renewable energy can improve public health. The air and water pollution emitted by coal and natural gas plants are linked to breathing problems, neurological damage, heart attacks, and cancer. Replacing these with renewables can reduce premature mortality and overall healthcare costs.

There are various types of renewable energy sources, each with different mechanisms and benefits.

Solar energy, the most abundant energy source on earth, harnesses the power of the sun. Photovoltaic (PV) solar panels convert sunlight directly into electricity, while concentrated solar power (CSP) uses mirrors to concentrate solar energy to drive traditional steam turbines.

Wind energy, another abundant source, uses wind turbines to generate electricity. The wind turns the blades, which spin a shaft connected to a generator that produces electricity.

Hydropower, the most mature renewable technology, captures energy from flowing or falling water. The mechanical energy of moving water is transformed into electrical energy in hydroelectric power plants.

Other renewable sources include geothermal energy, which utilizes the earth’s internal heat, and bioenergy, which uses organic material (biomass) to produce heat, electricity, or biofuels.

Despite the clear benefits, renewable energy faces several challenges. These include high upfront costs, intermittent energy production, and the need for significant infrastructure changes. However, technological advancements and policy support can overcome these hurdles.

Future prospects for renewable energy are promising. With the declining costs of renewable technologies, particularly solar and wind, and the global commitment to reduce greenhouse gas emissions, the share of renewables in the energy mix is set to increase. Furthermore, innovations like energy storage technologies and smart grids can help manage the intermittency of renewable energy.

In conclusion, renewable energy represents a clean, sustainable, and increasingly cost-competitive alternative to fossil fuels. Although it faces challenges, the future of renewable energy is bright, driven by technological advancements, policy support, and an urgent need to mitigate climate change and improve public health. As we move towards a more sustainable future, renewable energy will undoubtedly play a pivotal role.

Here are some of the most important pros and cons of using clean, renewable energy:

Advantages of renewable energy

Renewable energy has multiple advantages over fossil fuels. Here are some of the top benefits of using an alternative energy source:

Renewable energy won’t run out.

Renewable energy has lower maintenance requirements.

Renewables save money.

Renewable energy has numerous environmental benefits.

Renewables lower reliance on foreign energy sources.

Renewable energy leads to cleaner water and air.

Renewable energy creates jobs.

Renewable energy can cut down on waste.

1. Renewable energy won’t run out

Renewable energy technologies use resources straight from the environment to generate power. These energy sources include sunshine, wind, tides, and biomass. Renewable resources won’t run out, which cannot be said for many types of fossil fuels – as we use fossil fuel resources, they will be increasingly difficult to obtain, likely driving up both the cost and environmental impact of extraction.

2. Maintenance requirements are lower for renewable energy

Renewable energy systems usually require less overall maintenance than generators that use traditional fuel sources. This is because generating technology like solar panels and wind turbines either have few or no moving parts and don’t rely on flammable, combustible fuel sources to operate. Fewer maintenance requirements translate to more time and money saved.

3. Renewables save money

Using renewable energy can help you save money long term. Not only will you save on maintenance costs but also on operating costs. You don't have to pay to refuel when you’re using a technology that generates power from the sun, wind, steam, or natural processes. The amount of money you will save using renewable energy can vary depending on several factors, including the technology itself. In most cases, transitioning to renewable energy means anywhere from hundreds to thousands of dollars in savings—find out how much you can save by switching to solar energy .

4. Renewable energy has numerous environmental benefits

Renewable energy generation sources lead to lower greenhouse gas emissions than traditional fuel sources like natural gas. This means a smaller carbon footprint and an overall positive impact on the natural environment . During the combustion process, fossil fuels emit high amounts of greenhouse gases, which have been proven to exacerbate climate change, which in turn causes rising global temperatures and higher frequencies of extreme weather events.

The use of fossil fuels emits greenhouse gases and other harmful pollutants that lead to respiratory and cardiac health issues . With renewable energy, you’re helping decrease these pollutants' prevalence and contributing to a healthier atmosphere.

5. Renewables lower reliance on foreign energy sources

With renewable energy technologies, you can produce energy locally. The higher the amount of our energy use is renewable, the less we’ll rely on imported energy, and the more we’ll contribute to U.S. energy independence. Renewable energy sources can help us minimize the geo-political risks associated with fossil fuels, from trade disputes to political instability to pricing wars, which are often rooted in access to oil.

6. Renewable energy leads to cleaner water and air

When you burn fossil fuels to generate electricity, it contaminates the air and water we use. For example, coal power stations release high volumes of carbon dioxide, nitrous oxide, and harmful toxins like mercury, lead, and sulfur dioxide. Health problems from ingesting these elements can be dangerous and even fatal. Investing in renewable energy is a great way to work against these risks, as renewables have a far lower negative impact on our air and water. 

The use of fossil fuels emits greenhouse gases and other harmful pollutants that lead to respiratory and cardiac health issues . With renewable energy, you’re helping decrease these pollutants' prevalence and contributing to a healthier environment.

7. Renewable energy creates new jobs 

While the U.S. shifts its focus to combat global warming, we’re setting ambitious carbon-reduction goals that require labor to get the job done. Today, the renewable energy sector employs three times as many people as fossil fuels in the U.S. That number is expected to rise over the next few years—and as a plus, these jobs tend to pay above average wages, making it a desirable career option and an overall economic boom. 

8. Renewable energy can help solve our waste problem

Specifically, biomass energy can offer a significant benefit in this way. Biomass generators consume used organic products like vegetable oil, corn and soybean byproducts, and even algae to generate energy. Because of this, using biomass as an energy source can reduce the amount of waste that goes into landfills, which helps cut down on carbon emissions and environmental contamination.

Disadvantages of renewable energy

Renewable energy has many benefits, but it’s not always sunny when it comes to renewable energy. Here are some cons of renewable energy when compared to traditional fuel sources:

Renewable energy has high upfront costs.

Renewable energy is intermittent.

Renewables have storage capabilities.

Renewable energy sources have geographic limitations.

Renewables aren’t always 100% carbon-free.

1. Higher upfront cost

While you can save money using renewable energy, the technologies are typically more expensive upfront than traditional energy generators. To combat this, financial incentives such as tax credits and rebates are available to help alleviate your initial costs of renewable technology.

2. Intermittency

Though renewable energy resources are available around the world, many of these resources aren’t available 24/7, year-round. Some days may be windier than others, the sun doesn’t shine at night, and droughts may occur for periods. Unpredictable weather events can disrupt these technologies, and the amount of energy we can get from renewable power sources can be inconsistent. Fossil fuels are not intermittent, and power plants can be turned on or off at any time to provide an energy supply. Wondering if you should make the switch to renewables? Find out if an energy source like solar power is a good fit for you . 

3. Storage capabilities

Because of the intermittency of some renewable energy sources, there’s a high need for energy storage. Storage technologies are available but can be expensive, especially for large-scale renewable energy plants. It’s worth noting that energy storage capacity is growing as the technology progresses, and batteries are becoming more affordable as time passes.

4. Geographic limitations

The United States has a diverse geography with varying climates, topographies, vegetation, etc. This creates a beautiful melting pot of landscapes but also means that some geographies are more suitable for renewable technologies than others. For example, a large property in a rural area with open space may be an excellent place for a residential wind farm or a large-scale solar farm. At the same time, a townhome in a city covered in shade from taller buildings wouldn’t be able to reap the benefits of either technology. There are other options if your property isn’t suitable for a personal renewable energy technology. If you’re interested in solar but don’t have a sunny property, you can often still benefit from renewable energy by purchasing green power or enrolling in a community solar option .

5. Not 100% carbon-free

Although solar panels and other forms of renewable energy drastically reduce carbon emissions, these resources aren’t always completely clean. The manufacturing, transportation, and installation of renewable energy, like wind turbines, can create a carbon footprint since they’re usually produced in factories powered by fossil fuels —not to mention the diesel and gasoline needed to fuel the transport trucks. As the U.S. becomes more and more electrified – from solar panels on factories to electric transport trucks – carbon emissions associated with solar will continue to decrease.

6. Supply chain constraints

Renewables must have an effective distribution network created to transfer the energy where it’s needed on a large scale. These networks need non-renewable fuels to be generated, which offsets the benefits of renewable energy for a bit until it’s paid back. Additionally, politics can play a factor in installing renewable energy if it’s not a priority among local governments.

Types of renewable energy sources

There are a few types of renewable sources we can use for energy production: 

Wind energy leverages the power of wind motion to generate electricity created by the uneven heating of the Earth’s surface. 

Solar power uses energy from the sun to generate electricity and heat.

Hydropower utilizes fast-moving water to spin turbines and generate electricity. This is also known as hydroelectric power or hydroelectricity.

Biomass generates electricity from organic plant matter.

Geothermal energy leverages heat from inside the earth to generate electricity.

Tidal produces electricity with special generators that leverage the surges of the ocean created during rising and falling tides. Hydrogen: utilized as fuel and electricity when separated from other elements like oxygen.

Nuclear energy , while not technically renewable, is often lumped in with the abovementioned sources. Nuclear power has the potential to provide electricity generation on a massive scale with zero emissions, making it an intriguing part of our energy future.

Renewable energy has more benefits than drawbacks

When it comes to renewable energy, the positives outweigh the negatives. Transitioning to renewables on a personal, corporate, or governmental level will help you save money and promote a cleaner, healthier environment for the future.

Installing solar panels is one of the easiest ways to go green. By signing up on the EnergySage Solar Marketplace , you can compare multiple quotes from local, pre-screened installers to see what solar costs and savings for your property.

This Is the Future: Essay on Renewable Energy

Today the world population depends on nonrenewable energy resources. With the constantly growing demand for energy, natural gas, coal, and oil get used up and cannot replenish themselves. 

Aside from limited supply, heavy reliance on fossil fuels causes planetary-scale damage. Sea levels are rising. Heat-trapping carbon dioxide increased the warming effect by 45% from 1990 to 2019. The only way to tackle the crisis is to start the transition to renewable energy now. 

What is renewable energy? It is energy that comes from replenishable natural resources like sunlight, wind, thermal energy, moving water, and organic materials. Renewable resources do not run out. They are cost-efficient and renew faster than they are consumed. How does renewable energy save money? It creates new jobs, supports economic growth, and decreases inequitable fossil fuel subsidies. 

At the current rates of production, some fossil fuels will not even last another century. This is why the future depends on reliable and eco-friendly resources. This renewable energy essay examines the types and benefits of renewable energy and its role in creating a sustainable future.

Top 5 Types of Renewable Energy: The Apollo Alliance Rankings

There are many natural resources that can provide people with clean energy. To make a list of the five most booming types of renewable energy on the market today, this energy essay uses data gathered by the Apollo Alliance. It is a project that aims to revolutionize the energy sector of the US with a focus on clean energy. 

The Apollo Alliance unites businesses, community leaders, and environmental experts to support the transition to more sustainable and efficient living. Their expert opinion helped to compile information about the most common and cost-competitive sources of renewable energy. However, if you want to get some more in-depth research, you can entrust it to an essay writer . Here’s a quick overview of renewable energy resources that have a huge potential to substitute fossil fuels. 

Solar Renewable Energy

The most abundant and practically endless resource is solar energy. It can be turned into electricity by photovoltaic systems that convert radiant energy captured from sunlight. Solar farms could generate enough energy for thousands of homes.

An endless supply is the main benefit of solar energy. The rate at which the Earth receives it is 10,000 times greater than people can consume it, as a paper writer points out based on their analysis of research findings. It can substitute fossil fuels and deliver people electricity, hot water, cooling, heat, etc. 

The upfront investment in solar systems is rather expensive. This is one of the primary limitations that prevent businesses and households from switching to this energy source at once. However, the conclusion of solar energy is still favorable. In the long run, it can significantly decrease energy costs. Besides, solar panels are gradually becoming more affordable to manufacture and adopt, even at an individual level. 

Wind Renewable Energy

Another clean energy source is wind. Wind farms use the kinetic energy of wind flow to convert it into electricity. The Appolo Alliance notes that, unlike solar farms, they can’t be placed in any location. To stay cost-competitive, wind farms should operate in windy areas. Although not all countries have the right conditions to use them on a large scale, wind farms might be introduced for some energy diversity. The technical potential for it is still tremendous. 

Wind energy is clean and safe for the environment. It does not pollute the atmosphere with any harmful products compared to nonrenewable energy resources. 

The investment in wind energy is also economically wise. If you examine the cost of this energy resource in an essay on renewable resources, you’ll see that wind farms can deliver electricity at a price lower than nonrenewable resources. Besides, since wind isn’t limited, its cost won’t be influenced by the imbalance of supply and demand.

Geothermal Renewable Energy

Natural renewable resources are all around us, even beneath the ground. Geothermal energy can be produced from the thermal energy from the Earth’s interior. Sometimes heat reaches the surface naturally, for example, in the form of geysers. But it can also be used by geothermal power plants. The Earth’s heat gets captured and converted to steam that turns a turbine. As a result, we get geothermal energy.

This source provides a significant energy supply while having low emissions and no significant footprint on land. A factsheet and essay on renewable resources state that geothermal plants will increase electricity production from 17 billion kWh in 2020 to 49.8 billion kWh in 2050.

However, this method is not without limitations. While writing a renewable resources essay, consider that geothermal energy can be accessed only in certain regions. Geological hotspots are off-limits as they are vulnerable to earthquakes. Yet, the quantity of geothermal resources is likely to grow as technology advances. 

Ocean Renewable Energy

The kinetic and thermal energy of the ocean is a robust resource. Ocean power systems rely on:

• Changes in sea level;
• Wave energy;
• Water surface temperatures;
• The energy released from seawater and freshwater mixing.

Ocean energy is more predictable compared to other resources. As estimated by EPRI, it has the potential to produce 2640 TWh/yr. However, an important point to consider in a renewable energy essay is that the kinetic energy of the ocean varies. Yet, since it is ruled by the moon’s gravity, the resource is plentiful and continues to be attractive for the energy industry. 

Wave energy systems are still developing. The Apollo energy corporation explores many prototypes. It is looking for the most reliable and robust solution that can function in the harsh ocean environment. 

Another limitation of ocean renewable energy is that it may cause disruptions to marine life. Although its emissions are minimal, the system requires large equipment to be installed in the ocean. 

Biomass Renewable Energy

Organic materials like wood and charcoal have been used for heating and lighting for centuries. There are a lot more types of biomass: from trees, cereal straws, and grass to processed waste. All of them can produce bioenergy. 

Biomass can be converted into energy through burning or using methane produced during the natural process of decomposition. In an essay on renewable sources of energy, the opponents of the method point out that biomass energy is associated with carbon dioxide emissions. Yet, the amount of released greenhouse gases is much lower compared to nonrenewable energy use. 

While biomass is a reliable source of energy, it is only suitable for limited applications. If used too extensively, it might lead to disruptions in biodiversity, a negative impact on land use, and deforestation. Still, Apollo energy includes biomass resources that become waste and decompose quickly anyway. These are organic materials like sawdust, chips from sawmills, stems, nut shells, etc. 

What Is the Apollo Alliance?

The Apollo Alliance is a coalition of business leaders, environmental organizations, labor unions, and foundations. They all unite their efforts in a single project to harness clean energy in new, innovative ways. 

Why Apollo? Similarly to President John F. Kennedy’s Apollo Project, Apollo energy is a strong visionary initiative. It is a dare, a challenge. The alliance calls for the integrity of science, research, technology, and the public to revolutionize the energy industry.

The project has a profound message. Apollo energy solutions are not only about the environment or energy. They are about building a new economy. The alliance gives hope to building a secure future for Americans. 

What is the mission of the Apollo Alliance? 

• Achieve energy independence with efficient and limitless resources of renewable energy.
• Pioneer innovation in the energy sector.
• Build education campaigns and communication to inspire new perceptions of energy. 
• Create new jobs.
• Reduce dependence on imported fossil fuels. 
• Build healthier and happier communities. 

The transformation of the industry will lead to planet-scale changes. The Apollo energy corporation can respond to the global environmental crisis and prevent climate change. 

Apollo renewable energy also has the potential to become a catalyst for social change. With more affordable energy and new jobs in the industry, people can bridge the inequality divide and build stronger communities. 

Why Renewable Energy Is Important for the Future

Renewable energy resources have an enormous potential to cover people’s energy needs on a global scale. Unlike fossil fuels, they are available in abundance and generate minimal to no emissions. 

The burning of fossil fuels caused a lot of environmental problems—from carbon dioxide emissions to ocean acidification. Research this issue in more detail with academic assistance from essay writer online . You can use it to write an essay on renewable sources of energy to explain the importance of change and its global impact. 

Despite all the damage people caused to the planet, there’s still hope to mitigate further repercussions. Every renewable energy essay adds to the existing body of knowledge we have today and advances research in the field. Here are the key advantages and disadvantages of alternative energy resources people should keep in mind. 

Advantage of Green Energy

The use of renewable energy resources has a number of benefits for the climate, human well-being, and economy:

• Renewable energy resources have little to no greenhouse gas emissions. Even if we take into account the manufacturing and recycling of the technologies involved, their impact on the environment is significantly lower compared to fossil fuels. 
• Renewable energy promotes self-sufficiency and reduces a country’s dependence on foreign fuel. According to a study, a 1% increase in the use of renewable energy increases economic growth by 0.21%. This gives socio-economic stability.
• Due to a lack of supply of fossil fuels and quick depletion of natural resources, prices for nonrenewable energy keep increasing. In contrast, green energy is limitless and can be produced locally. In the long run, this allows decreasing the cost of energy. 
• Unlike fossil fuels, renewable energy doesn’t emit air pollutants. This positively influences health and quality of life. 
• The emergence of green energy plants creates new jobs. Thus, Apollo energy solutions support the growth of local communities. By 2030, the transition to renewable energy is expected to generate 10.3 million new jobs. 
• Renewable energy allows decentralization of the industry. Communities get their independent sources of energy that are more flexible in terms of distribution. 
• Renewable energy supports equality. It has the potential to make energy more affordable to low-income countries and expand access to energy even in remote and less fortunate neighborhoods. 

Disadvantages of Non-Conventional Energy Sources

No technology is perfect. Renewable energy resources have certain drawbacks too: 

• The production of renewable energy depends on weather conditions. For example, wind farms could be effective only in certain locations where the weather conditions allow it. The weather also makes it so that renewable energy cannot be generated around the clock. 
• The initial cost of renewable energy technology is expensive. Both manufacturing and installation require significant investment. This is another disadvantage of renewable resources. It makes them unaffordable to a lot of businesses and unavailable for widespread individual use. In addition, the return on investment might not be immediate.
• Renewable energy technology takes up a lot of space. It may affect life in the communities where these clean energy farms are installed. They may also cause disruptions to wildlife in the areas. 
• One more limitation a renewable resources essay should consider is the current state of technology. While the potential of renewable energy resources is tremendous, the technology is still in its development phase. Therefore, renewable energy might not substitute fossil fuels overnight. There’s a need for more research, investment, and time to transition to renewable energy completely. Yet, some diversity of energy resources should be introduced as soon as possible. 
• Renewable energy resources have limited emissions, but they are not entirely pollution-free. The manufacturing process of equipment is associated with greenhouse gas emissions while, for example, the lifespan of a wind turbine is only 20 years. 

For high school seniors eyeing a future rich with innovative endeavors in renewable energy or other fields, it's crucial to seek financial support early on. Explore the top 10 scholarships for high school seniors to find the right fit that can propel you into a future where you can contribute to the renewable energy movement and beyond.

Here are the big hurdles to the global push to build up renewable energy

The wind gusting across north German farm country brings much to the village of Sprakebuell: fog and rain from the sea, the occasional migrating stork, the faint smell of manure in the newly fertilized fields. And perhaps best of all, money — from selling the electricity generated by the wind turbines studding the flat green fields stretching out to the North Sea. A slice of the cash goes to the villagers themselves, with the local buy-in making this windy farming enclave near the border with Denmark a showcase for ways to push ahead with investment in renewable energy. (AP video shot by Pietro de Cristofaro)

The world’s governments have agreed they want to triple renewable energy by 2030, a goal laid out at the U.N. climate summit in December.

But right now, the post-pandemic global economy is throwing up obstacles that will need to be overcome if the goal is going to be met.

Here are the big hurdles to solar, wind and other renewable energy projects:

COSTLY CREDIT

Central banks in Europe and the U.S. have raised interest rates to combat inflation . That hits renewables harder than it does investment in fossil fuel projects.

Renewables have much higher up-front costs to build wind farms, solar arrays and more, and that borrowing costs money. After that, operating costs are negligible since the wind and sun are free, of course — but high interest rates have made it harder to get new projects off the ground.

In many cases, the answer is raising the agreed price of the electricity flowing to the grid to cover the added costs.

Everything costs more these days — not just food and rent, but the electric cables, power turbines, construction materials and services needed to build wind or solar installations. One exception: solar panels have plunged in price due to massive Chinese production.

SNARLED SUPPLY CHAINS

Order backlogs and supply delays are growing because there are shortages of skilled engineers, raw materials and a lack of manufacturing capacity for complex machinery needed for renewable energy projects.

An order for a new wind turbine or a transformer to connect to the grid can take months or longer to arrive than it did before the COVID-19 pandemic.

NOT IN MY BACKYARD

So-called NIMBY syndrome remains an issue in many places. Germany’s southern region of Bavaria, for example, is known for resisting the noise and appearance of wind turbines in its scenic landscape.

Installations have lagged in Bavaria and other regions despite the German government’s push for more renewable energy after losing affordable Russian natural gas used to heat homes, generate electricity and power factories.

WORSE TROUBLES IN DEVELOPING WORLD

Low-income countries have long faced much higher borrowing costs than the richer parts of the globe because government subsidies or other credit guarantees are uncertain.

The result is that the same solar park if built today costs twice as much in Ghana as it would in the U.S. because of interest rates alone, according to Todd Moss , a former State Department official who heads the Energy for Growth Hub in Washington.

Game-Changing High-Resolution Solar Data Enables Renewable Energy Expansion Across 2 Continents

New high-resolution solar data and analysis provides in-depth look at solar resources in africa, eastern europe, and the middle east.

Over 20 years of research in solar radiation at the National Renewable Energy Laboratory (NREL) is now poised to advance power system planning and solar energy deployment across Africa, Eastern Europe, and the Middle East. It comes in the form of a new, high-resolution solar timeseries data set on the Renewable Energy Data Explorer (RE Data Explorer) tool , tailored to the needs of stakeholders in energy sectors across national governments, academia, and private industry.

Development of the data set was motivated by the unique challenges facing two countries working with NREL and the U.S. Agency for International Development (USAID): Tanzania and Ukraine. In both countries, the availability of reliable, long-term resource data is a barrier in accelerating the deployment of renewable energy. In Ukraine, planners are working to find ways to rebuild and decentralize a grid that has been crippled by Russia's full-scale invasion. And in Tanzania—as is the case with many countries in Africa—reliable, detailed data has been historically difficult to access for planners and developers alike.

Partnering Through USAID for a Clean Energy Future

"I always admire the kind of support USAID provides to our partner countries because I don't see who else is going to do it," NREL's Tanzania technical lead Kwami Sedzro said. "If they did not provide that funding to help these countries and actually get their hands dirty on these challenges that the grid is facing now and will be facing with more renewables tomorrow, these projects might not happen."

Undertaking a project of this size required collaborative effort. The USAID Missions, or satellite offices, in Ukraine and Tanzania first worked with their partners at NREL to establish what the research and analysis priorities for each country would be. Based on those priorities, the team at NREL saw how this data set could address some of their overlapping needs.

"Rather than processing all of the data twice and splitting the regions, or just processing one region, it's way more efficient to do it together," NREL's Ukraine program lead Ilya Chernyakhovskiy said. "This way, both regions benefit."

Bird's-Eye View: How the Data Is Collected and Disseminated

RE Data Explorer is a publicly available geospatial analysis tool that gives users the ability to access renewable energy data customized to their needs. Its data can feed into tools such as the System Advisor Model , PVWatts , and others that can inform ongoing and future analysis, policymaking, and power system planning. RE Data Explorer has thousands of dedicated users who have shared how its capabilities are instrumental in their clean energy project development, long-term energy planning, and academic research.

To produce this new data set, the researchers compiled data sources covering Africa, Europe, and the Middle East from 2005 through 2022. Using imagery captured every 15 minutes by the European Union's (EU) Meteosat geostationary weather satellites, NREL's partners at the University of Wisconsin modeled key factors like cloud cover and composition. NREL also integrated satellite data from NASA representing aerosols (such as smoke, dust, and other airborne particulates) to estimate the solar irradiance reaching the surface on a four-kilometer (km) grid.

"The path of solar radiation through the atmosphere is very complex," Geospatial Data Science (GDS) group manager Galen Maclaurin said. "The most important component in modeling solar radiation as it reaches the surface is clouds. How thick are they? How high are they? What is the optical thickness? Are they formed mostly of liquid or frozen water, and what is the average particle size?"

The cloud properties are then run through NREL's radiative transfer model —called the Fast All-sky Radiation Model for Solar (FARMS)—on the laboratory's high-performance supercomputer, pixel by pixel, time step by time step, to create a high-resolution grid over the 18-year period of the final data set.

Having easy and free access to these robust data is vital for solar developers and potential purchasers of the electricity (e.g., a public utility) because it helps them estimate the expected amount of electricity generated for a given percentage of years of a project, which informs an important parameter called the exceedance probability.

"Those numbers are important because they're used to inform project risk and help secure financing. To calculate exceedance probabilities, you need the long-term record of the solar resource to represent interannual variability, and this feeds into project bankability," Maclaurin explained. "It provides an assessment of the generation potential and its uncertainty, and thus informs the project risk for a financier or a bank."

Building Ukrainian Grid Resilience Through Renewable Energy

In Ukraine, planners and developers are looking to incorporate more renewable energy as the country rebuilds its grid and searches for new means to become less dependent on foreign resources.

"The focus is all about making the grid more resilient during the war and rebuilding," Chernyakhovskiy explained. "One of the goals for the Ukrainian Ministry of Energy is to rely less on imports of natural gas and imports of diesel for backup generators. They hope to utilize domestic wind and solar resources while diversifying the geographic concentration of power system resources; that's really where they're interested in renewables right now."

A major hurdle Ukraine faces, however, is easily accessible, accurate, detailed information on its wind and solar output capabilities. Chernyakhovskiy said because Ukraine is not yet part of the EU, many of the more detailed data sets for the EU do not include Ukraine. "It really helps with planning and understanding where the resources are—where it is most cost effective to build distributed resources that will help to decentralize the grid," he explained.

Part of what makes grid planning in Ukraine difficult is the diversity of solar and wind resources and thus potential generation. The spatial and temporal variability of solar irradiance captured in this new data set, for example, gives planners and developers a clear picture of where they could competitively build photovoltaics (PV) as they work to decentralize the grid. This long-term, time series data set is vital in making new deployment a reality because it creates confidence in the analysis.

"It's an enabler to help planners, utilities, and developers accelerate their adoption of renewables because they can skip the step of doing a site-by-site assessment of the resource," Chernyakhovskiy said.

Beyond solar data, the USAID Ukraine Mission is interested in generating robust, long-term wind data as well. Using a novel methodology developed at NREL, a team in NREL's Strategic Energy Analysis Center is creating a high-resolution data set by using artificial intelligence (AI) algorithms to downscale (or increase the spatial and temporal resolutions) of existing climate models. To do that, they train the AI model on high-resolution modeled data for the United States then apply it to lower-resolution climate data for Ukraine. This method builds on recent work by USAID and NREL's Advanced Energy Partnership for Asia to produce high-resolution wind data for Southeast Asia .

"We're pretty excited about applying that kind of state-of-the-art method to Ukraine, and that really gave us the ability to cover the whole country for such a long time series at such high resolution," Chernyakhovskiy said.

The new Ukraine wind data will be released in the coming weeks on RE Data Explorer , followed by a webinar later this spring.

Making a Difference in Tanzanian Grid Planning

On the other side of the equator, the USAID Tanzania Mission is working to help the country achieve its own renewable energy goals. Currently, Tanzania is working toward decarbonizing its grid, with a 30–35% conditional emissions-reduction target by 2030, per Tanzania's Nationally Determined Contributions in the United Nations Development Programme's Climate Promise.

By making the new, long-term time series data set easy to access and freely available to the public, Tanzania and other African nations are better poised to accomplish their energy goals.

"This is a big deal to have a solar data set that we can trust for Africa; it's going to be a game changer," Sedzro said. "Providing these data is going to be very helpful for the industry as a whole in Africa, because then people can be motivated to invest in the technology."

Sedzro is going to Tanzania in April to train planners, utilities, and developers in Tanzania and other African countries like Ghana to use the solar data set to effectively plan PV deployment.

"They're able to see how much they can get out of the data, and they can do their math and decide whether they want to go here or there based on the solar time series data," he explained. "You can see the irradiance values that you get today, and you can use that data to predict what's going to happen tomorrow. You're planning a system for tomorrow."

Portugal ran only on renewable energy for over 6 days

This video is part of: Centre for Energy and Materials

Portugal has achieved a remarkable milestone in its renewable energy journey, running entirely on renewable sources for over six days. This groundbreaking feat sets a new national record of 149 hours, surpassing the previous record of 131 hours set in 2019.

A leading force in renewable energy

Portugal stands as a European frontrunner in clean energy initiatives. In 2016, the country established its ambitious "net zero by 2050" target, three years ahead of most other EU nations. Portugal also closed down its last coal plant in 2021, nine years ahead of its own 2030 target. With the commitment to phasing out gas plants by 2040, Portugal is paving the way for carbon neutrality as early as 2045.

Global recognition for Portugal's efforts

Portugal's dedication to clean energy has not gone unnoticed. The country ranks among the top 20 nations best prepared for the energy transition, as recognized by the World Economic Forum's Centre for Energy and Materials.

The country's success demonstrates the feasibility of a clean energy future and paves the way for a sustainable, secure, and equitable energy landscape for all.

Climate Change: Renewable Energy Sources Essay

Introduction, works cited.

Today, more and more people are talking about renewable energy sources and environmental conservation. Climate change is especially damaging because it makes everything else even more dangerous, and deforestation and oil extraction are threat accelerators. Climate change is the biggest threat to humanity, and deforestation and “oil dependency” only exacerbate the situation and rapidly kill people.

20% of Amazon is already lost, along with the development of a society that increasingly consumes meat ( Fueling the Fire ). With global demand for beef on the rise, Brazil has also become a major exporter and is looking to increase its market share, partly by selling to the US ( Fueling the Fire ). Along with deforestation, the oil industry is still developing in different regions. For example, the US military is the largest consumer of oil in the world ( Fueling the Fire ). Such spheres cannot be changed without decisive political influence.

Leaders are known to see oil as an easy power to obtain. In addition, politicians largely set the direction of citizens’ thoughts. For example, agriculture is actively supported in Brazil, but few people think about what it costs this happens. It is important to set an example and keep people’s desire to move from destroying the planet to supporting it. Renewable energy will do to coal and oil what automobiles did to horses and carts ( Fueling the Fire ). That is the same development as mining and processing but with a lesser threat to the planet and humanity.

While there is a need to develop and grow, this should not come at the expense of environmental destruction. Therefore it is important to invest in the development of renewable energy sources. Today there are many ways to use solar energy, reuse water, and the like. Previously, I did not think about the fact that meat production brings such great harm to the environment. It is a matter of habit, and we can reduce our meat consumption, affecting the conservation of forests and our world.

I Work in Supply Chain Logistics. Here’s What I Advise After the Tragedy in Baltimore.

By Ryan Petersen

Mr. Petersen is the chief executive of Flexport, a supply chain technology and logistics company.

The immediate impact of the collapse of the Francis Scott Key Bridge in Baltimore on Tuesday was viscerally clear: In minutes, the Baltimore Harbor went from a humming logistics hub to a chaotic search and rescue operation. Two construction workers who had been fixing potholes on the bridge were pulled from the water, with six more missing and presumed dead.

As a native of Maryland, I grew up driving through the Baltimore Beltway with my family to see the Orioles play at Camden Yards, which is near Baltimore’s Inner Harbor. Seeing container ships sail through the port was one of my earliest memories of global shipping.

Last year the Port of Baltimore processed 1.1 million 20-foot containers’ worth of cargo, making it the ninth-busiest port, based on trade volume in the United States, and the most important port serving our nation’s capital. It’s also the busiest U.S. port for car shipments, with more than 800,000 vehicles moving through its waters onto its docks and across its roads and railways in 2023.

As rescue workers and salvage crews work tirelessly to recover bodies and restore access to the harbor, our national supply chain is kicking into high gear to absorb the aftershock of the bridge collapse. Ship traffic to the Port of Baltimore is being rerouted to nearby ports, including one in Norfolk, Va., and the Port of New York and New Jersey. These changes come at a time when global supply chains are already stressed, with ships changing course to avoid Houthi attacks in the Red Sea and low-water restrictions limiting capacity through the Panama Canal. The looming contract expiration for the International Longshoremen’s Association in September also creates uncertainty for businesses that rely on cargo sent by sea.

As a result of all this precariousness, many companies that typically move goods through East Coast ports are already asking about rerouting their cargo through West Coast ports, opting to truck or rail the goods across the country to avoid delays. Ports around the country are preparing to absorb surges in volume as companies reroute around the Port of Baltimore and avoid the East Coast more generally.

Baltimore has the fourth-largest port on the Eastern Seaboard

The East Coast of the United States received over 450 million tons of cargo by ship in 2021. Baltimore’s 50-foot channel and berths allow it to handle larger ships than many other U.S. ports.

If there’s one lesson we learned about the supply chain in recent years, it’s that sudden increases in container volumes arriving in U.S. ports can compound into congestion and delays. This was most evident during the peak of the pandemic-induced supply chain crisis, when over 100 ships were waiting off the coast to unload at U.S. ports.

We don’t yet know what caused the power loss that led to the crash in Baltimore or what could be done to avoid tragedies like this in the future. As we mourn the loss of life, what’s obvious to those of us in the shipping industry is that chronic underinvestment in America’s ports makes them ill suited to handle the surging volumes they are likely to experience as traffic planned for Baltimore is shifted to neighboring ports.

America’s ports are vital to American interests and are the backbone of our economy. Yet some of our largest ports can handle vessels only two-thirds the size of the world’s largest and most efficient container ships, which today primarily sail on the Asia to Europe trade lane, avoiding the United States altogether.

While recent plans by the Biden administration to invest billions in new, U.S.-manufactured container cranes appear to be a step in the right direction, it remains to be seen whether we’ll actually be getting larger, more efficient cranes capable of servicing the biggest ships or if we’re simply replacing the existing cranes with similar models while doing little to improve the throughput of our ports.

America’s supply chain infrastructure is central to our country’s prosperity. We should invest far more to dredge our ports and enable them to handle larger ships, build new rail connections, automate port operations and employ container dispatching software to increase the throughput of trucks loading and delivering containers. The failure to do so leaves us weaker and more vulnerable when catastrophe strikes.

The good news is that off-the-shelf technology already exists and has been successfully used in ports around the world. Port modernization would lead to high-paying jobs in and around American ports while making our infrastructure and economy more resilient to shocks like the one we’re experiencing in Baltimore.
