The main advantage of geothermal energy is that it can be exploited easily and inexpensively in regions where it is abundantly available in hydrothermal resen/oirs, whether it is used for electricity production or for dircct-usc heat. Gcothcrmally produced electricity from dry-steam sources is vei y cheap, second only to... [Pg.578]

Utilization of geothermal energy is of two types, electric power generation and direct use of the heat. In geothermal electric power plants, steam is used to drive turbines in much the same way as in conventional fossil fuel plants. The main difference is that in fossil fuel plants the steam is generated by boiling water by... [Pg.297]

Fiydrothermal plants produce electric power at a cost competitive with the cost of power from fossil fuels. Besides generating electricity, hydrothermal energy is used directly to heat buildings. Across the United States, geothermal hot-water reservoirs are much more common than geothermal steam reservoirs. Most of the untapped hot-water reservoirs are in California, Nevada, Utah, and New Mexico. The temperatures of these reservoirs are not hot enough to drive steam turbines efficiently, but the water is used to boil a secondary fluid, such as butane, whose vapors then drive gas turbines. [Pg.655]
