Both energy sources could be viable options in the future but as of now wind energy is a much better choice than solar, solar is more versatile, more efficient, and far cheaper than photovoltaic technology. Many countries see renewable energy as the future and have made plans to foster its use. It is estimated that wind will provide 5 to 10% of the United States power needs by the year 2020, and the Euro... ... middle of paper ... ... array. The average price per kilowatt from an industrial size photovoltaic array is about 3,000 dollars (Messenger & Goswami, 2007), while the average price for a wind turbine can be as low as 1,000 dollars (Hinrichs & Kleinbach, 2005). Wind is the fastest growing renewable source of energy in the world today.
Electricity and good health have a lot in common, because when you have it, you don 't think about it. When you don 't have it, that 's all you think about. With our current society’s dependence on electricity and the evolving technological advancements, certainly modern civilization isn 't going anywhere without power. Over the next 50 years, unless patterns change dramatically, energy production and use will contribute to global warming through large scale greenhouse gas emissions — hundreds of billions of tons of carbon in the form of carbon dioxide. Nuclear power could be one option for reducing carbon emissions.
The United States spends about $700 billion to $1 trillion in the process of fossil fuel burning. The United States produced about 28% of all greenhouse gas emissions in 2010 (US Global Change Research Program. 2009). According to Environment America, about $23 trillion will be spent on fossil fuels by 2030. The cost of wind power has gone down by about 85% making it more money efficient than fossil fuels (Natural Resources Defense Council) (Environment America).
Although petroleum is cheaper, nuclear energy presents itself as a much stronger alternative to petroleum. This is because the cost of petroleum mining within the next fifty years or so will be too large to be an efficient energy source. A switch to nuclear energy may be more efficient as well as less hazardous to the environment as nuclear power plants emit much less carbon dioxide than fuel plants do. The World Nuclear Association went on to say “Greenhouse gas emissions of nuclear power plants are among the lowest of any electricity generation method and on a lifecycle basis are comparable to wind, hydroelectric and biomass.” Nuclear plants also produce a greater amount of energy since “In 2012, the "average" nuclear power plant in the United States generated about 11.8 billion kilowatt-hours (kWh). There were 65 nuclear power plants with 104 operating nuclear reactors that generated a total of 769 billion kilowatt-hours (kWh), or 19% of the nation's electricity”(EIA).
An example of a wind power farm would be the San Gorgonio Pass Wind Farm in Riverside County, California. Geothermal energy and biomass are the next two efficient renewable energy sources. Scientists generate geothermal energy by digging beneath the earth’s crust and using that heat to produce energy. This form of energy costs little to extract, ... ... middle of paper ... ... if you compare the advantages and disadvantages, hydropower is the best form of renewable energy. Renewable energy sources are the best way to generate electricity because they create little harm to the environment.
With future expansion and newer solar cells, the power production could be increased to about 60-70% of the U.S.A's needs. Cold fusion will most surely be the newest type of energy leading us into the 21st century, producing energy that is cheaper, safer and easier to generate then any existing source.

These are scary facts that must no longer be overlooked in the name of profit. Nuclear power is a major pollutant and must be recognized as one.
This clean energy abundance will destroy the need for costly conflicts and imports of oil. Decreased spending on homeland security and oil imports would dramatically reduce the debt (17.5 Trillion) and be well worth investment in clean energy. Clean energy investment will send the energy industry through the roof and grow the economy. The American Recovery and Reinvestment Act and the Clean Energy and Security Act will also generate around 150 billion dollars in clean energy investments. This major spending is mainly coming from private sector investors.
What would happen to our world if our energy unexpectedly disappeared? Fossil fuels are very important to our world because they provide an overwhelming majority of our world energy. So, what happens when they run out? This research paper confronts this question with a balanced view attempting to address the issue of what sources might provide energy in the future and come to an objective conclusion. As the world enters a new century, new sources of energy such as wind, solar, and hydrogen power need to be developed to help the world keep running on all cylinders.
It seems like everything we use involves electricity. Our lives revolve around electricity and without it our world would be in a hullabaloo. As our days go on our electricity output increases and our Fossil Fuel storage decrease. “We can thank Fossil Fuels for providing over 80% of our energy we use around the world.” (CNN Wire) As we look ahead to our future, we have to find another source to get our energy. Renewable energy comes into play because according to several scientists, easily retracted fossil fuels will be used up during the 21st century.
