Document Summary
High t rocks within economic and electrical drilling depths. Need carrier fluid to transport heat to surface. Extracting energy associated with heat and pressure from natural hot water and steam (primordial heat + radioactive decay of uv, th & k) Generating electricity at many sites in the world or heating energy for buildings, etc. Vast amount of geothermal energy resources (500 times oil and has resources, if only 1% could be captured from upper 10 km) U. s. (2009) 3,153 mw installed capacity; 188 projects underway to provide 7,000 mw power to. 15 states, feeding demand of -7. 6 million people and replacing coal-fired power plants in. Currently very minor electrical generating capacity in canada (good potential for high t resources in b. c. , yukon & nwt) Canada (2010) 55,000 shallow heat exchanges (geo-exchange units) installed. Over half of this energy used for space heating, one third for heated pools, remainder in small industrial and agriculture applications.
