Sources Of Energy Essays - Energy Development, Energy Economics

Sources Of Energy Sources of Energy Have you ever thought about how we get the energy to run the things we take for granite every single day. There are many sources of energy that that are used for transportation, heat, light, and the manufacturing of goods of all kinds. The development of science and civilization is closely linked to the availability of energy in useful forms. The seven main energy sources are fossil fuels, hydroelectric, solar power, win power, geothermal, nuclear power, and biomass energy. By harnessing the sun, wind, falling water, plant matter, and heat from the earth, energy planners expect to decrease the environmental impact on energy use. Most of the nonhydro renewable power comes through some form of combustion, such as the burning of biomass, landfill gas, or municipal solid waste. Little electricity comes from solar, wind, and geothermal sources. Factors that are increasing interest in renewable energy include cost advantages in niche markets, regulatory pressures, customer service requirem ents, fuel flexibility, and security. One of the biggest source of energy is fossil fuels. Fossil fuels have served as a reliable source of heat for cooking and warmth since the beginning of history. The common fossil fuels are coal, peat, lignite, petroleum, and natural gas. Coal gas, coke, water gas, and producer gas can be made by using coal as the principal ingredient. These such artificial gases can be used for fuel, illuminant, and a source material for the manufacturing of synthetic ammonia. Gasoline, kerosene, and fuel oil are made from petroleum. They are mainly used for transportation if the fuel is used in a liquid form. Natural gas is a natural mixture of gaseous hydrocarbons found from the ground or obtained from specially driven wells. The composition of natural gas varies in different localities. It is used extensively as an illuminant and a fuel. Some geologists theorize that natural gas is a by-product of decaying vegetable matter in underground strata. Others think it may be primordial gases that rise up from the mantle. Natural gas was known to the ancients but was considered by them to be a supernatural phenomenon because it appeared as a mysterious fire bursting from the ground. Gas is also a fossil fuel. It is a gaseous substance that burns in the air and releases enough heat to be useful as a fuel. It is advantageous if a fuel gas is readily transportable through pipes and is easily liquefied. Oil gas is a type of gas made by applying heat to various petroleum distillates. Its principal use is as a supplement to natural gas during periods of heavy demand. Coal gas may be any of a variety of gases produced by heating coal in the absence of air and driving off the volatile constituents. It is not as high in fuel value as other gases and often contains tars, light oils, ammonia, and hydrogen sulfide. These common fuels are used in industry, transportation, and the home are burned in the air. Scientists research and develop alternatives to gasoline every single day. One possible alternative is methanol, which can be produced from wood, coal, or natural gas. Another possibility is ethanol. Ethanol is an alcohol produced from grain and currently used in some typ es of US gasoline. A example of this is gasohol. It is a compressed natural gas, which is much less polluting than gasoline and is currently used by a half-million vehicles around the world. Petroleum is a fossil fuel thought to have been formed over millions of years from incompletely decayed plant and animal remains buried under thick layers of rock. The widespread burning of petroleum products as fuels has resulted in serious problems of air pollution. Oil spilled from tankers and offshore wells has damaged ocean and coastline environments. The environmentally disruptive effects of oil wells have sometimes led to strong opposition to new drilling, as in wilderness areas of Northern Alaska. Most of the energy consumed is ultimately generated by the combustion of fossil fuels, such as coal, petroleum, and natural gas. The world has only a finite supply of these fuels, which are in danger of being used up. Also the combustion of these fuels releases various pollutants, such as monoxide and sulfur
