2.1. How much geothermal electricity is currently supplied to the U.S.?

According to the GEA's 2013 Annual US Geothermal Power Production and Development Report (April 2013), the U.S. currently has approximately 3,386 MW of installed geothermal capacity, more than any other country in the world. "At the end 2012, geothermal energy accounted for roughly a third of a percent of total installed operating capacity in the United States. Additionally, Geothermal was about 1% of new renewable energy projects brought online in 2012.2 While this number may seem small on a national scale, geothermal is a significant portion of renewable electricity generation in the states of CA and NV. While the majority of geothermal installed capacity in the US is concentrated in California and Nevada, geothermal power plants are also operating or under construction in Alaska, Hawaii, Idaho, Oregon, Utah, Washington and Wyoming. A significant amount of additional geothermal capacity -- 574 - 620 MW -- could become operational by January 2016 if companies who participated in GEA’s survey bring their plants online on time."

 2.2. Are geothermal projects currently being developed in the U.S.?

According to the GEA's 2013 Annual US Geothermal Power Production and Development Report (April 2013): "Installed geothermal capacity increased from 3,187 MW in early 2012 to 3,386 MW in February of 2013. As the economy recovers and the recent language alteration of the PTC tax credit effects the geothermal industry, significant growth is expected in 2013 and subsequent years. From the information GEA gathered from reporting companies, up to 14 plants could become operational in 2013 and 9 new plants in 2014 and 10 more plants in 2015, by over 20 different companies and organizations making 2013, 2014, and 2015 three of the most significant boom years for geothermal in decades."
