Energy Alternatives: Renewable Energy In The United States

In the United States, 42 percent of the nation’s electricity is generated by burning coal as coal is cheap and plentiful.

Have you ever wondering where your electricity comes from? How your car uses gasoline to run? What about how these things impact our environment or how we are going to keep producing them? As a country, we need to start looking ahead to the future and planning for what is to come. Currently, 86% of America’s energy comes from petroleum, natural gas, and coal. All of these resources will run out eventually. We need renewable energy sources that will keep producing in a clean, more efficient way for a long time. Before committing to an idea and going all the way with it, we need to compare all the different energy sources available to the U.S. and choose the one that is best for everyone.

Energy is an important part of life producing the power of movement, heat, and production of electricity in many different ways. Therefore, choosing the correct source of energy is important for the environment and humans. Renewable energy that produces electricity never runs out, causing a lower environmental impact. Solar, Biomass, Wind, Geothermal, and Hydropower energy should be used globally to produce electricity. On the other hand, producing electricity from nonrenewable energy sources can be very harmful to humans and the environment. Humans can easily be dependent on it, which may not be the best option when it comes to finance, efficiency, sustainability and more. Approximately 52% of the US electricity comes from polluting sources like natural gas, oil, nuclear, and hydropower that have a lot of disadvantages effecting the environment in a negative way.

Switching from the expensive oil to alternative fuels has moved from a dream to reality. Today, there are dozens of alternatives to oil that are currently available us to be used. One alternative to oil that is being used more today is ethanol. Derived from plant materials, ethanol can be a cheaper, cleaner alternative to the gasoline that our vehicles run off. When going to gas pumps, one will notice that much of the gasoline is up to 10 percent of ethanol. According to our text, most ethanol in the U.S. is made from corn, yet ethanol can be made from any biomes-- including garbage. (Turk & Bensel, 2011)

The development of science and technology has led to people considering using alternative fuels to generate electricity. There are many alternative fuels that can generate electricity, such as natural gas, nuclear energy, wind energy, hydraulic power and so on (Fossil Fuels Used to Generate Electricity Power Plant Emissions of North America). According to the statistics by the U.S. Energy Information Administration in 2009, the usage of coal was still the largest source to generate the power. Sources of electricity in the United States were generated by 44.9% of coal, 20.3% of nuclear, 23.4% of natural gas, 1% of petroleum, 6.9% of hydroelectric conventional and 3.6% of others (Electric Power Monthly with Data for February 2014). Coal

According to statistical data “Almost all (95%) of the world's transportation energy comes from petroleum-based fuels, largely gasoline and diesel.” (United States Environmental Protection Agency, n.d.).

This class is an elective for me, so I didn’t really know much about energy technologies before taking it and I must say my opinions on different sources of energies have changed completely. For the whole semester now I’ve been trying to think about what I wanted to write about for my final paper, but nothing really tickled my fancy until watching the film “Pump”. This film has opened my eyes to different sources of fuel we could use in vehicles, but really one particular one stood out to me the most and that was ethanol. The reason this particular one stood out to me the most was the fact that Brazil, an entire country, has switched over to ethanol gas.

“According to the Renewable Fuels Association, ethanol production in 2013 added more than 87,000 direct jobs across the country, $44 billion to the gross domestic product, and $30.7 billion in household income” ("Ethanol Benefits and Considerations"). A nonrenewable resource, gasoline, currently occupies the United States’s spot as the main fuel source. This not only means our fuel supply will eventually be depleted, but the country’s main fuel supply is harming the environment. Throughout the last decade, the idea of ethanol, a renewable resource, starting to replace gasoline has been debated, but until the last few years, remained implausible. Recent technology innovations, enhancing the performance of ethanol fuel, transformed this idea into a reality. The adoption of ethanol as the main source of our country’s fuel not only benefits the country as a whole but individuals’ vehicles .

Around 86 percent of our power is produced from these fills sorts, with 73 percent from coal and 13 percent from natural gas. Around the globe it's much the same, with fossil fuels being utilised for power, warming and fuelling vehicles. (Originenergy.com.au)

The Industrial Revolution sparked a need for large sources of energy. Human and animal labor could not provide the power necessary to power industrial machinery, railroads, and ships. The steam engine and later the internal combustion engine provided the bulk of the energy required by the industrial age. Today most nations are still heavily reliant on energy that comes from combustion. Usually coal, petrolium, and natural gas are used. Some hydroelectric, wind power, and nuclear fission sources are used, but in the US they accounted for less than 20% of the total energy consumption in 1997 (1). Many experts are worried that natural resources such as coal and petrolium are being depleted faster than they are being replenished, which could

The world around us mostly runs on fossil fuels in order to produce electricity; however, there will be a period that comes where we will run out of those fossil fuels. We only have so much time before a crisis hits and we have nothing left to produce the energy we need. In order for our country to produce the energy and electricity we need, we must do something about it. As a country, we must figure out how we can make the switch to using more renewable energy before it is too late and we run out of fossil fuels.

Figure above shows the percentage of electric energy in the U.S. Over 50% of the energy is from coal. This year nuclear energy use was increasing; however, it creates radioactive. Natural gas will pollute the air and caused global warming. According to the National Oceanic and Atmospheric Administration, wind is the fastest growing energy resource. It increased by 46.6 percent by 2005.

The use of ethanol as an alternative fuel for gasoline has attracted considerable interest, mostly in the US (corn-based ethanol), Brazil (sugar cane-based ethanol); and Sweden as E85 (15% gasoline-85% ethanol) has been commercially used for a couple of decades [129]. Ethanol is also used as a drop–in fuel up to 10% in gasoline (E10) in a number of markets such as Austral-ia [96]. There are a number of advantages of blending ethanol in gasoline: (1)

Of these two types of energy production, fossil fuels like oil, gas, and coal make up about ninety percent of the world’s energy usage. Nuclear power takes up five percent of this equation, with the remaining renewable energy resources splitting

For years man has relied on energy in order to be successful in life. The industrial revolution relied on coal for the new inventions brought into the world. Life as has never been the same since then. However since that time, there has been little done to improve on energy efficiency and humans still primarily rely on fossil fuels for energy. For over a hundred years the Earth has become more polluted and dirtier than ever before. Now, with new, innovative technology there is an opportunity to change that and to rely on renewable, cleaner sources of energy. The main source of energy for the world should be alternative energy instead of energy from fossil fuels.
