Energy Market Potential - A newly-released report
by Research and Markets explores the factors associated with utilizing the
actual potential of geothermal energy, covering all the technological
details, along with issues and challenges faced during the utilization of
geothermal energy. The report covers major projects, power plants,
players in the industry, including U.S. government role. (Business Wire;

Releases Major Report on Geothermal Energy - A
comprehensive new MIT-led study of the potential for geothermal energy
within the United States has found that mining the huge amounts of
heat that reside as stored thermal energy in the Earth's hard rock
crust could supply a substantial portion of the electricity the United
States will need in the future, probably at competitive prices and
with minimal environmental impact. (PESN; Jan. 22, 2007)

Potential of Geothermal Power - The concept is simple to understand:
earth's core heat transforms water into steam, which in turn causes a
turbine to revolve. Scientists say this geothermal energy, clean,
quiet and virtually inexhaustible, could fill the world's annual needs
250,000 times over with nearly zero impact on the climate or the
environment. (Yahoo! News; Aug. 4, 2007) (See Slashdot
