| Abstract |
Geothermal direct use, estimated for 2006 on the basis of previous and growth rate data, reached about 650 MWt installed capacity and 5500 TJ/yr heat production, mostly from geothermal heat pumps (GHP). This corresponds to the saving of 130?000 toe fossil fuel. Geothermal energy in Switzerland thus reduces the emission of CO2 by about 400?000 tons per year. GHP installation prices decrease whereas drilling for GHPs increases. The largest Swiss geothermal project, DEEP HEAT MINING in Basel, has been suspended in December 2006 due to earthquake activity triggered by water injection for stimulation. National research activities as well international cooperation are accompanied by increasing educational efforts. |
