Alternative Energy
Alternative energy refers to energy sources that have no undesired consequences such for example fossil fuels, nuclear energy and falling water. Fossil fuels are coal, petroleum and natural gas. There are some characteristics of the fossil fuels that made the concept of alternative energy come into place. (Alternative Energy)
One of the fossil fuels, Petroleum, forms a thin film around the grains of the rock where it formed. Pressure from the overlying rock and water move the petroleum and gas through the rock until it reaches a rock type or structure that stops it. If natural gas is present, it occupies space above the accumulating petroleum. Such accumulations of petroleum and natural gas are the sources of supply for these energy sources. The supply of petroleum and natural gas is limited. Most of the continental drilling prospects appear to be exhausted, and the search for new petroleum supplies is now offshore. In general, over 25 percent of our nation 's petroleum is estimated to come from offshore wells. Imported petroleum accounts for more than one-half of the oil consumed, with most imported oil coming from Mexico, Canada, Venezuela, Nigeria, and Saudi Arabia. (Tillery,2010)
A fossil fuel, coal, formed from an accumulation of plant materials that collected under special conditions millions of years ago. Stagnant swamp water protected the plants and plant materials from consumption by animals and decomposition by microorganisms. Over time, chemically altered plant materials collected at the bottom of pools of water in the swamp. This carbon-rich material is peat. Peat is used as a fuel in many places in the world. The flavor of Scotch whisky is the result of the peat fires used to brew the liquor. Peat is still being produced naturally in swampy areas today. Under pressure and at high temperatures peat will eventually be converted to coal. The mineral impurities leave an ash when the coal is burned, and the sulfur
