Geothermal Energy – Calipatria, CA CalEnergy Vice President Mark Gran introduces the companys 340 megawatt geothermal plant on the southern shore of the Salton Sea. The plant produces enough energy to power around 300000 homes. The Imperial Valley has the potential to produce a stunning 2300 megawatts of this renewable resource. Thats enough energy to power more than 2 million homes. One major challenge is building transmission lines to deliver that energy to the large, urban areas that need it.
