How does geothermal energy create electricity?

  • Geothermal energy is created by turbine generators that use the steam, heat and hot water from geothermal reservoirs

How does geothermal technology work ?

  • Utilizes heat. Reducing dependence on fossil fuels, and the global warming and public health risks that result from their use.

How is this resource gathered/created ?

The areas with the highest underground temperatures are in regions with active or geologically young volcanoes. These "hot spots" occur at plate boundaries or at places where the crust is thin enough to let the heat through. The Pacific Rim, often called the Ring of Fire for its many volcanoes, has many hot spots, including some in Alaska, California, and Oregon. Nevada has hundreds of hot spots, covering much of the northern part of the state.

US consumption ?

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."
