Emissions-free electricity from small geothermal sources

Lisa Cohn of Energy Efficiency Markets interviews Bill Olson, senior vice president of business development for ElectraTherm, about how the company produces emissions-free electricity from small geothermal heat sources. Employing ElectraTherm’s products to recycle industrial waste heat on a wide scale in the U.S. could generate the equivalent electric output of ninety-two 500-MW gas-fired combined cycle plants without any fuel consumption or emissions, he says.
