Document Summary
Extracting energy associated with heat and pressure from natural hot water and steam (primordial heat + radioactive decay of u, th & k) Generating electricity at many sites in the world or heating energy for buildings. Vast amount of geothermal energy resources (500 times of oil and gas resources, if only 1% could be captured from upper 10km) To be an economic energy supply, a) high temperature rocks within economic & drilling depths: need carrier fluid to transport heat to surface; c) need permeability in hot rocks. Us: 3567 mw installed capacity, 188 projects undergoing to provide 5000 mw power to 9 states, feeding demand of about 7. 6 million people and replacing coal-fired power. (plants in. Ca: currently very minor electrical generating capacity in canada, though there is good potential for high temperature resources in b. c. , yukon and nwt). In 2010, 55000 shallow heat exchange unit (geo-exchange units) installed.
