CAUSE GEOTHERMAL ENERGY REPLACES THE USE OF IMPORTED ENERGY SOURCES, SUCH AS OIL. IS IT COST EFFECTIVE? THE LOWEST COST GEOTHERMAL PRODUCERS ARE NOW SELLING GEOTHERMALLY GENERATED ELECTRICAL POWER FOR $0.015 PER KILOWATT HOUR. AT THE GEYSERS, THE WORLD'S LARGEST GEOTHERMAL FIELD, POWER IS SOLD AT ABOUT 3 TO 3.5 CENTS PER KILOWATT HOUR. A POWER PLANT BUILT TODAY WOULD PROBABLY REQUIRE ABOUT 5 CENTS PER KILOWATT HOUR. SOME GEOTHERMAL POWER PLANTS RECEIVE MUCH MORE PER KILOWATT HOUR DURING SOME TIME PERIODS BECAUSE OF VARIOUS INCENTIVES RELATED TO RELIABILITY OF GENERATION AND POWER PROVIDED DURING PEAK DEMAND.BINARY CYCLE/FLASH STEAM POWER PLANTS THE TWO DIAGRAMS BELOW SHOW HOW A BINARY CYCLE POWERPLANT WORKS AND HOW A FLASH STEAM POWER PLANT WORKS. ALSO THERE IS A PICTURE OF A REAL BINARY POWER PLANT AND FLASH STEAM POWER PLANT....
