In this Alternative Sources of Energy essay, the author argues that the Sun and wind have the potential to reduce our dependence on fossil fuels and lower carbon emissions. Read the paper to learn about the challenges, limitations, and benefits of implementing alternative energy sources. A particular part is dedicated to the importance of government policies in promoting the development and use of alternative energy sources. Overall, the essay on alternative sources of energy presents a comprehensive overview of the current state of renewable energy and its potential for shaping our future.

Introduction

Solar power, course of action, works cited.

The world has been overly relying on oil as a source of energy to fuel most of its operations. It is important to note that as much as 80% of the world’s energy comes from fossil fuel. Unfortunately, the fossil deposits we have in the world cannot last forever. They will be depleted one day and cause a lot of problems in the world.

Therefore, efforts should be made to ensure that other sources of energy are found so that when fossil fuel gets depleted the world does not come to a halt. In this regard, many people especially in the U.S. have been concerned with the steps that the government is taking towards encouraging development of other sources of energy.

Consequently, the government has been urged to reduce restrictions impeding the development of renewable sources of energy and increase funding of the same. However, to address this issue, it is better to understand some of the sources renewable energy.

Among the proposed sources of power to be used is solar energy. Solar energy is a renewable source of energy because the sun has been there and can only be absent for a very short period of time. On the same note, harnessing of solar energy is noise proof which means that noise pollution is avoided when using solar power (Boxwell 58).

Similarly, solar power is environmental friendly because it does not produce any form of pollution. In addition, equipments used in the production of solar power are cheap to maintain thus the long run cost of production is low. Moreover, it is easy and cheap to install appliances of solar power.

Similarly, the electricity produced from solar energy can be used to power virtually every thing that uses power (Boxwell 59). It is also important to note that the production of solar power does not lead to environmental degradation like digging up the ground or deforestation.

However, solar power has its disadvantages. To begin with, some people have argued that the initial cost of installing solar power harnessing equipment is very high. Additionally, harnessing of solar power is affected by whether and cannot be done during cloudy or rainy days and at night. Therefore, another source of energy is needed to act as a back up (Boxwell 60).

On the other hand, wind energy is also another source of energy that can replace fossil fuel. Wind energy does not emit green house gases which are dangerous to the environment. Furthermore, no fossil fuels are burnt to produce wind energy thus it does not pollute the environment (Miller and Scott 407). Besides, extraction of wind energy is more efficient given the advancement in technology.

The turbines used to produce wind power only occupy little space at the base leaving room for other activities to be done on the ground. Moreover, wind energy is highly applicable in under developed parts of a country and can add to the tax base of the area.

In addition, renewable sources of energy, wind being among them, require minimal subsidies to maintain. On the same note, the cost of producing wind power is constant and therefore prices for wind power do not fluctuate. Most importantly, wind is free and thus cost of producing wind power is low in the long run (Miller and Scott 407).

It is crucial, however, to highlight that wind power has its share of disadvantages. Firstly, wind power depends on the flow of wind. On the days when the weather is calm wind power might not be generated. On the same note, the initial cost of producing wind power is quite high and individuals may not afford it (Miller and Scott 408). Lastly, power produced by the turbines is insufficient compared to power produced by fossil fuels.

Despite the disadvantages of wind and solar power, their advantages are definitely more. They are renewable and therefore they will never get depleted. Sooner or later the government will have to find alternative ways of producing power.

Consequently, it is high time that the government increased its financial support in the production of the two types of power (Miller and Scott 407). Reduction of restrictions is necessary but it might not be sufficient given the heavy initial cost. Similarly, renewable sources of energy, especially wind and solar power, are both economically and environmentally viable in the long run hence the need to invest in them.

The fact that the country currently satisfies most of its energy requirements should not blind our eyes. We will need to think of how we will operate in future. The fossil fuel that forms the giant part of energy source will definitely be exhausted with time.

It will be a great disservice to the future generations if we do not find sustainable energy sources. Consequently, the government has no option but to encourage the production wind and solar energy.

Short Essay on Renewable Energy (200 – 250 Words)

Renewable energy is produced from the resources that are available in nature. Energy can be easily produced from renewable resources that are available free of cost. We can use renewable energy without the fear of its running out. This energy is also called as ‘green energy’ and ‘clean energy’.

Some renewable energy is solar energy, hydro energy, wind energy, geothermal energy, and biomass energy. Today we are mostly dependent on non-renewable resources like coal, petroleum, etc that will end one day. Also, they are harmful to the environment. Hence, renewable energy is a good alternative for today as well as for tomorrow.

As the name suggests, renewable energy can be easily regenerated. Renewable energy does not produce harmful gases and is hence considered safe for the environment. On seeing the current condition of the environment, renewable energy is the need of an hour.  

However, renewable energy does have a black side. Generally, price is the superior reason that restricts the usage of clean energy in the world. It also requires higher maintenance and installation price. Another disadvantage is the location-centric. Not every type of renewable energy is produced everywhere. A particular atmosphere is required to produce renewable energy.

On noticing the consequences of non-renewable energy, indeed, the future can only be safe if we use renewable energy.

Long Essay on Renewable Energy (500 – 600 Words)

Introduction

Electricity is a secondary form of energy. It is produced from different sources of energy. Energy can be renewable or non-renewable. Renewable energy can be renewed or re-generated easily but the non-renewable resources are limited on the earth. They can’t be generated again. Therefore, renewable energy is much better than non-renewable energy.

Sources of Renewable Energy

There are five major sources responsible for generating renewable energy. They are:

• Solar energy: Sun is the major source of renewable energy that is termed as solar energy.  The light and heat of the sun are used to produce energy. Solar cookers, solar panels, or solar cells are used to utilize solar energy. Scientists are also preparing to launch solar-powered cars.
• Wind energy: Wind is also used to produce energy. Windmills run using turbines and generators are constructed to generate wind energy. Wind energy is a good contributor to global energy demand.
• Biomass energy: Wastes from plants and animals are used to produce energy, which we call biomass energy. Biomass is an eco-friendly method of energy production. Different methods are used to produce biomass energy from biofuels.
• Geothermal energy: Geothermal energy is produced from the heat below the earth’s surface. This energy can be used to produce electricity, heat buildings, bathing, etc.
• Hydropower energy: The force of water is used to produce energy and is referred to as hydropower energy. Hydropower is more reliable than other renewable sources. The construction of reservoirs, canals, dams, etc helps to control the flow of water which is later, used to run turbines to produce electricity.

Advantages of Renewable Energy

The primary advantage of renewable energy is that it can be renewed easily. It is the only option that will meet the energy requirement of today as well as tomorrow. Unlike fossil fuels that are limited on the earth, we can use renewable energy for a lifetime. Renewable energy is good for both humans and the environment. Non-renewable energy like fossil fuels causes pollution and environmental hazards like acid rain, global warming, etc. The amount of carbon emissions from renewable energy is much low than those of non-renewable energy.

Therefore, depending on renewable energy will save us from this serious issue. Renewable energy is the most reliable form of energy and we can also say that it is the future of the world’s energy needs.

Disadvantages of Renewable Energy

We all know the importance and benefits of renewable energy but there are some limitations to its usage. The main disadvantage is the cost. The cost of generating energy from renewable resources is very high when compared to that of non-renewable sources. People find burning coal cheaper and easier than installing a solar panel.

Most of the renewable resources depend on natural sources that can be obtained in a particular location. For example, solar energy cannot be fruitful for cold locations or geothermal energy can only be obtained in a location where fast-flowing water resources are available. This limits the use of renewable resources to a great extent. However, they cannot be considered fully safe for living things and the environment. The hydroelectricity project has an adverse effect on aquatic life and the ecosystem.

The increasing population demands an increase in energy consumption. Energy is necessary for home, business, and almost every work. Thanks to innovation and invention that helps in utilizing renewable resources and maintaining a sustainable level of energy in the world.

I hope the above provided essay on renewable energy is easy to understand. We should use energy efficiently to live a healthy and peaceful life.

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.

Alternative Energy Sources

Different types of alternative energy sources.

For several decades there has been quite a bit of discussion about the damage caused to the environment by littering and pumping harmful gases into the atmosphere. Many ideas on how to protect the environment have been put into place, either by social consciousness or by law, to help clean up the earth and reduce future pollution. These ideas range from recycling, to picking up trash, to using alternative energy sources. We’re going to focus on the benefits, possibilities, and barriers that come with the use of alternative energy.

Alternative energy is best defined as the use of energy sources other than traditional fossil fuels, which are considered environmentally harmful and are in short supply. Fossil fuels consist of natural gas, coal, and oil. Currently, fossil fuels are the most used energy source to heat our homes and power our cars. To use these fuels as energy they must be burned, and burning of these fuels releases harmful gases into the atmosphere, causing pollution. Another problem associated with fossil fuels is their supply: it is unclear how long oil and coal reserves will last with our current rate of consumption or if new reserves will be found before current reserves run out. Estimates on how long current reserves will last run anywhere from 20 years to 400 years. Because of these concerns with fossil fuels, more people are beginning to use alternative energy sources. Some popular alternative energy sources are wind power, hydroelectricity (water power), solar power, biofuels, and hydrogen. These fuels all have two things in common:   their small environmental impact on the earth and their sustainability (never ending supply) as an energy source.

So if alternative energy sources are supposed to fix our environmental and supply problems, why have we not switched to using alternative energy sources solely? Well, the simple answer is that alternative energy sources also tend to have common barriers to their use as widespread energy sources. These barriers include location, storage, high cost to produce and use, and inconsistent energy supply.

Wind power is not a new source of energy. For hundreds of years, human beings have used the power of the wind to send their ships across the oceans and used windmills to grind grain, pump water, and saw wood. The power of the wind can most easily be seen by using a child’s windmill. The basic concept is that when the windmill is held up in oncoming wind currents, the wind catches in the curve of the blades, causing the windmill to rotate. This is the wind’s energy at work.

A wind turbine works much like an old fashioned windmill in that it also uses the wind’s kinetic energy (energy caused by motion) to turn the blades. The blades spin a shaft that is connected to a generator . A generator is a device that converts mechanical energy into electrical energy. Inside the generator, a copper coil is moved through a magnetic field by the shaft that is connected to the moving blades. This movement causes an electric current to flow through the copper coil. When the generator is mechanically powered by the wind via a wind turbine, it can make electricity.

Wind power is consider a clean energy source because there are no chemical processes involved in wind power generation.   No by-products are made, such as carbon dioxide, to cause air or water pollution. Wind generation is a renewable resource that will never run out, and it is a great energy source for people who live in remote areas where it may be difficult to supply them with power by use of wires connected to a power plant that is far away. The actual space taken up by a wind turbine is relatively small compared to other alternative energy sources. A diameter of only about six feet is needed at the base, making the real estate cost for a wind turbine relatively cheap.

A problem with using wind power is that it is not always a guaranteed energy source. When the wind is not blowing, electricity cannot be generated, and a back up energy source must be relied upon. Wind farms are needed for commercial generation, which raises the issue of scenery obstruction caused by so many wind turbines lined up next to each other. Many people do not want to see multiple wind turbines outside their kitchen windows. Another problem is the hazard these moving blades cause for birds flying through the area. New construction of wind turbines have larger blades that rotate at slower speeds so that birds may see them and not get caught in the blades.

Hydroelectricity

The term hydroelectricity refers to the generation of electricity through the power of water. “Hydro” comes from the Greek word hydra which means water. Like wind power, using water for power also has earlier roots than modern times. Water wheels were first used to capture water’s energy and mechanically grind grain. They were later used for pumping water, crop irrigation, driving sawmills, and powering textile mills. Today we use water turbines much like wind turbines to generate electricity.

The most common source for capturing the power of water today is the hydroelectric power plant. Hydroelectric power plants usually require a dam built on a river that creates a reservoir of water. The dam holds the water back until gates open to allow the water to run through. With the help of gravity, the water runs through a pipeline, called a penstock , to the turbine. The elevation change through the penstock helps the water to build up pressure as it approaches the turbine. The moving water reaches the turbine and spins the turbine’s blades. Above the turbine is a generator, which is connected to the turbine by a shaft. Like the generator in a wind turbine, the generator in a water turbine also produces electricity by moving a series of copper coils past magnets. A transformer then takes the electricity produced by the generator and converts it to a higher voltage current. The electricity is now ready to power businesses and homes via power lines.

Hydroelectric power is a renewable source that causes no waste or pollution. Unlike wind power, hydroelectricity is more reliable. The energy can be stored up for use by the dam holding back water until more energy is needed. However, hydroelectricity requires a large power plant, which is very expensive to build. These power plants also require building dams on rivers, changing the ecosystem of the area. Instead of a river in the area above the dam, there is now a large lake that expands over the habitats of land animals. The amount and quality of water running out of the dam can have an adverse (negative) effect on the plants living on the land and in the water below.

Solar Power

Solar power is simply using the sun’s light as energy. This can be done by using a solar cell to convert the sun’s light into electricity, using solar thermal panels that use sunlight to heat air and water, or passively using the sun’s energy by letting sunlight enter through windows to heat a building. The total energy we receive from the sun each year is around 35,000 times more energy than what the human race uses, meaning this power source is probably one of the best sources for the future. The challenge lies in harnessing and storing this energy in a cost effective way.

One of the most popular ways of harnessing the sun’s energy is by using photovoltaic (PV) cells, which are also known as solar cells . PV cells work by absorbing the particles of solar energy that make up sunlight. These particles are called photons. The absorbed photons are transferred to a semiconductor material, usually silicon. (Semiconductors are substances that conduct electricity more easily than insulators but not as easily as conductors like copper.) Electrons in the semiconductor are knocked loose by the incoming photons, leaving spaces in between the bonds of the atoms. Both the loose electrons and the open spaces can carry an electrical current. PV cells are built with one or more electric fields to control the flow of the electrons, thus controlling the flow of the current. When metal contacts are placed on the top and the bottom of a PV cell (much like a battery), we can extract this electrical current to use it in our everyday lives.

Like the above alternative energy sources, solar power is renewable and nonpolluting. Unlike wind turbines and hydroelectricity, photovoltaic conversion to electricity is direct, meaning an expensive, bulky generator is not required. Like wind turbines, solar power can also be used in remote locations where it would be economically impossible to provide power from a far away power plant. Solar power can also be very efficient in providing heat and light through the use of solar ovens, solar water heaters, solar home heaters, and the use of skylights.

Solar power shares a common drawback with wind turbines: their unpredictability. Solar power only works when the sun is out, making a PV cell ineffectual at night and hit or miss during a cloudy day. For these times, power storage needs to be implemented in order to make solar power the main power source. Many forms of solar power are still not economically practical. Photovoltaic power stations are expensive to build and are only about 10% efficient in producing energy. It takes about five years for a power station to produce the same amount of energy that went in to the initial building of the power station. With current technology, solar power is best used on a smaller scale, such as individual homes.

There are many energy sources that fall under the category of biofuels: biomass, biodiesel, ethanol, and methanol are just a few. The basic idea here is to use organic matter (usually plant derived) as a fuel source. Biomass refers to using garbage and vegetation as a fuel source. When garbage is decomposing (breaks down) it produces a gas called methane that can be captured and later burned to produce energy that can be turned into electricity. Vegetation can be burned directly, much like fossil fuels, to generate energy. While these methods do help in the cost and sustainability areas, they still cause a significant environmental impact much like fossil fuels.

Ethanol and methanol are two alcohols that are made from biomass. Ethanol is usually made from corn, but can also be made from agricultural, logging, and paper wastes. Methanol is also known as wood alcohol because it can be made from wood; however, most methanol is produced using natural gas because it is cheaper. Whereas biodiesel is the alternative for diesel engines, ethanol and methanol are the alternatives for gasoline engines. Most private vehicles have gasoline engines and can use ethanol blends with little or no modification of the engine. Ethanol also burns cleaner and produces lower greenhouse emissions than gasoline. However, comparing the price of ethanol with the price of gasoline is a bit tricky. One gallon of pure ethanol contains 34% less energy than one gallon of pure gasoline. A common ethanol blend, E85, is a mixture of 85% ethanol and 15% gasoline and produces 27% less fuel economy than 100% gasoline. So in order for E85 to cost less than gasoline, it must have more than a 27% price reduction than gasoline. Gasoline that costs $3.00 a gallon has the same fuel economy as E85 that costs $2.19 a gallon.

Biodiesel is made by combining a vegetable oil, such as canola or soy oil, and an alcohol such as methanol or ethanol. A catalyst is often added to increase the rate of the reaction between the vegetable oil and alcohol. This process to make biodiesel is called transesterification (for more information on transesterification, click here ). This chemical process causes the glycerin to separate from the fat in the vegetable oil, leaving behind two products: methyl ester or ethyl ester (the chemical name for biodiesel) and glycerin. Glycerin is a valuable byproduct often used to make soaps and other products.

Biodiesel is considered an ideal fuel because it is clean burning and can be used in any diesel engine. It is often mixed with regular petroleum diesel to avoid complications with cold weather usage. Pure biodiesel gels at a higher temperature than petroleum diesel. (Soy biodiesel bought in the U.S. begins to gel up at about 40 °F.) This means that it is harder to start a truck in sub-zero temperatures that runs on biodiesel than a truck that runs on petroleum diesel. Biodiesel costs more to produce and therefore costs more to buy than petroleum diesel. Otherwise, biodiesel tends to work as well as petroleum diesel. Pure biodiesel and biodiesel blends release fewer greenhouse gases, are biodegradable (able to decompose by natural processes), and can extend the life of diesel engines. Some filling stations that provide diesel also provide biodiesel. These retailers are more prevalent in the Midwestern states. Here is a map of retailers who sell biodiesel in the United States.

One of the most promising alternative fuels of the future is hydrogen. Its large supply and clean burning properties have many scientists and environmentally conscious citizens looking to it as the solution to replacing fossil fuels without drastically changing our current lifestyles and dependency on personal vehicles. Unlike fossil fuels, it is a non-carbon fuel so when it is burned it does not produce more carbon dioxide. Hydrogen is the simplest and most abundant element found on earth and is found in water, air, and all organic matter. However, even with these all these positives, two major problems stand in the way of using hydrogen as a main fuel source: its production and its storage.

There are two main ways to produce hydrogen: electrolysis and reforming natural gas. Electrolysis involves using an electric current to split the water molecule into hydrogen and oxygen. (To separate hydrogen at home using electrolysis, click here .) In the process of reforming natural gas, methane (which is a principal component in the natural gas used to produce hydrogen) is heated using steam, causing a reaction between the methane and water vapor that produces hydrogen, carbon dioxide, and trace amounts of carbon monoxide. Currently, both methods use natural gas to produce hydrogen. Reforming methane requires splitting the hydrogen from the carbon in methane, but electrolysis requires a power source to produce electricity to split the water molecule. Natural gas is most often used as the fuel source to produce this electricity. Since both of these methods require the consumption of natural gas to produce hydrogen, hydrogen costs more to use than natural gas.

Hydrogen can be used to power vehicles in two ways: to produce electricity in a fuel cell or be used directly in an internal combustion engine. Using hydrogen in a fuel cell is the cleaner method. A fuel cell is an electrochemical device that combines hydrogen and oxygen to produce electricity. Its only by-products are heat and water, which do not pollute the environment. When using hydrogen directly in an internal combustion engine, the hydrogen is burned with the outside air (which is about two-thirds nitrogen) producing nitrogen based oxide gases, which cause some pollution, and water vapor. Whether hydrogen is used directly in an internal combustion engine or in a fuel cell, both methods require the storage of hydrogen for use as the vehicle is driven. On a weight basis, hydrogen produces the most energy when burned compared to any other fuel — one pound of hydrogen produces 2.6 times more energy than one pound of gasoline. However, hydrogen is a gas so one pound of hydrogen takes up four times the amount of space as does one pound of gasoline. For example, a vehicle that holds 15 gallons of gasoline would need to hold 60 gallons equivalent value of hydrogen to produce the same amount of energy. The tank in the vehicle would have to be the size of two average bathtubs to hold the hydrogen needed in order to drive a reasonable distance without refueling. However, the 15 gallons of gasoline would weigh 90 pounds whereas the 60 gallons of hydrogen would only weigh 34 pounds.

To solve this space problem, hydrogen can be turned into a liquid which takes up less space than hydrogen as a gas, but in order to turn hydrogen into a liquid, it must be cooled and kept to -423.2 ° Fahrenheit. Storing hydrogen as a gas or a liquid is very expensive and cumbersome. Still, there is hope on the horizon. The United States Department of Energy has offered grants to scientists to find ways to improve the storage of hydrogen on small vehicles by improving compression and liquefaction of hydrogen, using metal hydrides to store more hydrogen without adding too much weight to the vehicle, and improving the use of adsorbent materials to collect and hold hydrogen gas on the surface of a solid. However, even if we overcome the storage problem, we still face the hurdle and expense of replacing all gasoline-powered cars with hydrogen-powered cars and replacing gasoline-filling stations with hydrogen-filling stations to become a hydrogen-based America.

Short And Long Paragraphs About Energy and its Crises

Today, we have abundant energy sources such as oil, coal, gas, and uranium. This energy is used to generate electricity for our homes, as well as other modes of transportation such as trains and planes.

What happens if there isn’t any energy available? Without transportation or lighting, among other things that require fuel or electric current to operate, the world will be very distinct from what it is now. In 1987, the International Atomic Energy Agency (IAEA) was founded, with its headquarters in Vienna.

Because nuclear energy is seen as a safer and better form of energy, it is used to promote peace. The future challenge is to develop new sources of renewable energy, such as solar and wind power, that are both sustainable and affordable.

Without any form of energy, the world would be a very different place. There would be no electricity-powered transportation, lights, or electronic devices —basically nothing. This is due to the fact that all of these devices require some form of fuel or electricity to function. Thankfully, we have a variety of energy sources to choose from, which include oil, coal, gas, and uranium.

However, as our population grows and energy demand rises, we will need to find new renewable energy sources that are both sustainable and affordable. Solar and wind power are two excellent examples of renewable energy sources worth investigating.

They are both environmentally friendly and cost-effective, and they have the potential to reduce our reliance on fossil fuels. So, let’s keep looking for new energy sources and working toward a more sustainable future!

Although there are numerous energy sources available, some of the most common include oil, coal, gas, and uranium. Because nuclear energy is seen as a cleaner and safer form of energy, one organization, the International Atomic Energy Agency, works to promote peace through it.

The future challenge will be to develop new renewable energy sources that are not only sustainable but also affordable, such as solar and wind power.
