The number of geothermal energy projects in the U.S. grew by 26% last year, to 188, as development of the alternative energy source spread from the western states to the Gulf Coast.
Mississippi, Louisiana and Texas reported their first geothermal projects in 2009, according to a new report from the Geothermal Energy Association in Washington, while Utah quadrupled the number of projects, New Mexico tripled them and Idaho doubled them. Other states with projects are Alaska, Arizona, California, Colorado, Hawaii, Nevada, Oregon, Washington and Wyoming.
Nine states currently are generating electricity from geothermal energy.
In all, said the association, 15 states had 188 projects under way by the end of 2009 that will represent a capital investment of $35 billion when completed.
In fact, said GEA executive director Karl Gawell, "California could achieve its 2020 goal for global warming emissions reductions just by keeping energy demand level and replacing its coal-fired generation with geothermal."
