Geothermal potential in Pacific NW

A county government entity in Washington state is drilling to find a heat source to power a local geothermal power plant.  Of course,

“It’s not a foregone conclusion that geothermal power here will pan out. Based on the information from these five wells, the PUD will pick a spot to drill a deeper, a 2,000-foot-test hole next summer. If the data from that well is positive, the PUD would search for nearby sites where a plant could be built and actual geothermal wells could be drilled.  Wells for hot water or steam likely would be 5,000 to 7,000 feet deep, Collar said.”

If this trial turns out to be successful, it could stimulate significant additional exploration for geothermal sources near metro areas on the west side of the Cascades. This type of power plant would likely be very low impact in terms of environmental concerns.
