Energy sources and the interchangeability of energy, propose a replacement for fossil fuels (petroleum, coal, natural gas), as

Each source has its own characteristic significance and one needs to identify its suitability based on local possibilities and circumstances (Renewable energy sources in the United States 2011). Hydropower Hydropower means using water to produce electricity. This is a clean way of producing electricity. Small and big dams both can be used to turn turbines. Hydropower is suitable where ever flowing waters from rivers are available. Currently, around 7% of the electricity in the US is produced by hydropower sources. Major hydropower projects in the US are located on the Colorado River, the Tennessee Valley. Solar Energy Sun is the most potent source of renewable energy. Efficient solar technologies can give the most viable solution to the world energy needs. Technologies to harness this particular source are advancing rapidly. In the US, summer is the most appropriate season to harness solar energy due to longer daylight hours and a high angle. California State in the US boasts several solar installations and solar energy so harnessed is clean and nonpolluting. Wind Power Wind is yet another renewable source of energy that is clean and available most part of the year. Coastal regions where wind velocity is greater than normal are most suitable for Wind turbine installations. The western part of the US is the most potential region where winds velocity is high. Wind turbines are usually installed at higher altitudes to harness continuous but less turbulent stream of winds. Currently, wind energy meets only 1 percent of the total energy needs of the country but its use has been rising rapidly. Geothermal Power Geothermal source of energy uses Earth's heat to produce electricity. Geothermal source of energy is available continually in certain regions of the US and it is based on the premise that temperature inside our earth is fairly constant throughout the year. The various technologies are in use and those can be described as geothermal heat pumps, deep reservoirs and direct-use systems. Geothermal power plants recover heat from water or steam to convert it into electricity. Heat pumps are used for heating purposes at residential and commercial buildings. Binary-cycle geothermal power plants can use water with even moderate temperatures – in the range of 38 to 149 degree centigrade; thus, it has been economical to harness this clean source of energy. Nevada, Hawaii, Utah and California in the US are known to have geothermal power plants in operations. Biomass Power Biomass or Biopower is the second largest source of energy among renewable in the US. Available biomass such as grassy or woody plants, food crops, residues from farms, organic wastes obtained from municipalities and industries are used as direct heating or to produce electricity. Since Biopower is available from plant sources, it can be produced in any part of the country. Biomass self-balances carbon release in the environment hence is nonpolluting. A Clear Case of Responsible Stewardship and Integrity While buying fossil fuels, one is paying only for a commodity and does not compensate for environmental degradation and health damages caused to fellow citizens. Using any of the renewable sources of energy and discarding the use of fossil fuels firmly establishes that we not only respect our environment but are deeply concerned with preserving the same for our future ...Show more

Summary

Energy Sources as a Replacement to Fossil Fuels The world's largest energy requirements including those of the US are currently being met through fossil fuels such as coal, diesel, gasoline and natural gas. The environmental and health impacts of fossil fuels are significant and include global warming, oil spills, pollution, acid rain, rising sea levels and many more…

Energy Sources
Since the world, whose primary goal is to produce more and to earn more, is fuelled by energy, the use of fission to generate has a lot of financial benefits. Specifically, many Americans believe that the use of nuclear energy is a really good alternative to the use of fossil fuels that are becoming “more scarce and more expensive”.

An arguement for the use of Natural Gas as a replacement for Fossil Fuels
In a world which is largely powered by coal and petroleum, the Energy Information Administration believes that there will be an increase of natural gas production to 28 trillion cubic feet per year as the price of crude oil increases (Loveless, 2012). There are several reasons for this move and there are a number of benefits that the United States can obtain from a proposed dependency on natural gas.

Harnessing solar energy to reduce dependence on fossil fuels
Various life forms evolved and perished in the process. The remains of these life forms were acted upon by the sun's heat and light and fossils were formed. In a way, fossil fuels are also derived from the action of the sun's energy. Fossil fuels are the fuels that have developed over millions of years through various natural processes.

The main advantage is low cost and environmentally friendly design of collectors. Thesis Wind energy is one of the most cost effective solutions to traditional resources like coal, oil or nuclear power. The threat of future shortages of liquid and gaseous fossil fuels can be relieved to some extent by converting coal to oil and gas.
