  	Citation × Citation Citation Abstract Copy Title: Geothermal District Heating Projects Author: Lineau, P. J. The geothermal energy stored within the interior of the earth amounts to a significant quantity which, if fully exploited, could supply the energy needs of man for a millennia. Low temperature hydrothermal resources underlie vast areas of the United States as illustrated on Figure 1, particularly in the western half of the country. The U.S. Geological Survey has identified 1,346 hydrothermal convection systems of which 1,294 have temperatures less than 300°F and are considered suitable for direct heat applications (Reed, '1983). Resource temperatures greater than 300°F are considered economic for electrical generation. Quantitative estimates of identified low and intermediate temperature (less than 300°F) geothermal systems contain 68.3 million billion Btu's of beneficial heat for 30 years Title: Geothermal District Heating Projects Author: Lineau, P.

Year: 1983 If you lived in Reykjavik, the capital of Iceland, you would heat your home with geothermal water. The city's district heating system dates back to 1930, when 15 lis of 90-100 C water was piped 2.8 km to heat 70 homes, one school and a swimming pool. The Reykjavik District Heating Service is now the largest of its kind in the world. If you were visiting Reykjavik, you would soon discover that the city is geothermally heated. The geothermal water is of good quality and is used directly for bathing and washing. Taking a bath or shower you are likely to smell the water, because of the hydrogen sulphide. Reykjavik is by no means unique in having a geothermal district heating system. There are now many such systems in Iceland; they serve more than three quarters of the total population Title: Geothermal in Iceland: It's Only Natural Author: Gudmundsson, J. S.

Year: 1984 Geothermal resource development in Klamath Falls increased dramatically with completion of Phase I of the city geothermal heating system in 1982. Phase I can supply 14 government office buildings and 127 homes in two low-income residential areas with heat and hot water. However, Phase I has not been used because of a lack of historical data regarding long-term sustainability of the resource. This lack of technical knowledge has resulted in conflicts over how to use the resource. This report describes both the cumulative scientific knowledge and the conflicts and groups involved, and offers a comprehensive view of geothermal development in Klamath Falls Title: Geothermal Development in Klamath Falls, Oregon Author: Forcella, L.
