The U.S. geothermal power industry is poised for a bit more rapid growth now that the U.S. Department of Energy's geothermal development program is maturing with demonstration-stage pilots. This acceleration of growth also will be spurred on by an increasing number of municipalities and utilities that are turning to geothermal as an alternative energy option for either renewable mandate or investment reasons, industry executives say. While the U.S. geothermal power market is still somewhat tepid in comparison to the international market, U.S. technology exports will help U.S. companies weather the wait for a more rapid domestic market expansion.
