8、o produce electrical energy on a large scale). Electrical energy sources can be broken down into two broad categories, thermal and non-thermal. A brief discussion of varying alternatives follows below.Thermal SourcesvCoal. (Substantial reserves and the development of the necessary technology) mean t
9、hat (coal is and will continue to be a major energy source). Presently coal represents about 45 of total electrical energy sourcesvOil and Natural Gas. In the 1950s and 1960s there was a trend toward greater utilization of these fuels because of their superior combustion properties. However, (the co
10、st, scarcity, and competition from petroleum products )indicate that (while these fuels will remain important for electrical energy production, their percentage share of total energy supply will decrease).vNuclear Fission from Uranium. Since the 1950s fission reactors have been used commercially for
11、 the production of electrical power. Uranium resources in the U.S. are slightly less than oil and gas reserves. Serious problems relating to environmental impact have accentuated social concern and some legal and regulatory constraints have been placed upon the development of this resource. A pruden
12、t growth in the comparative importance of this source is expected, along with a Iegitimate and proper concern for the environment. vSolar. It is possible to collect solar energy directly and concentrate it on steam boilers. The major problems are the diffuse nature, which requires large areas for co
13、llection, and the unreliability of atmospheric conditions. At present there are no commercial installations. This source is particularly attractive as no “fuel” is required and because of its non-polluting characteristics.vNuclear Fusion. Certain types of nuclear reaction are possible, where certain
14、 light nuclear particles can be combined, or fused, into heavier particles. Such reactions produce pure energy. The most attractive feature here is that common elements such as hydrogen isotopes can be used as fuel, making this source essentially inexhaustible. The difficulty is that a sustained fus
15、ion reaction requires production of extremely high temperatures and particle concentrations for a sufficiently long time. The technical problems associated with this are formidable and most experts will not predict commercial installation until well into the next century.vGeothermal. Heat from the e
16、arths interior and subsurface water combine to produce natural steam, which can be used for electricity production. Total reserves are estimated at up to about half of the total gas and oil reserves. Expectations are that this resource will continue to be developed, but that it will only make a minor contribution to the total energy supply.vBiomass. Synthetic gas can be p
