Both have great potential to solve many US energy needs.
Thank you for a very interesting article today goes to the respected voice for the environment, Bob Berwyn. Up and over on The Summit County Citizens Voice.
"SUMMIT COUNTY — Geothermal resources in the U.S. could produce at least 3 million megawatts of power — more than 10 times the amount currently produced by coal-fired power plants today — according to a new report issued by Southern Methodist University’s Geothermal Laboratory.
The study, funded by a grant from Google.org, used Google Earth technology to help map vast reserves of a renewable energy resource that is realistically accessible using current technology.
The estimated amounts and locations of heat stored in the Earth’s crust included in this study are based on nearly 35,000 data sites and will help pinpoint locations for resources capable of supporting large-scale commercial geothermal energy production.
Based on the additional data, primarily drawn from oil and gas drilling, larger local variations can be seen in temperatures at depth, highlighting more detail for potential power sites than was previously evident in the eastern portion of the U.S. For example, eastern West Virginia has been identified as part of a larger Appalachian trend of higher heat flow and temperature.
Conventional U.S. geothermal production has been restricted largely to the western third of the country in geographically unique and tectonically active locations. For instance, The Geysers Field north of San Francisco is home to more than a dozen large power plants that have been tapping naturally occurring steam reservoirs to produce electricity for more than 40 years...."
