Private Geothermal Energy

Nice animation of how a private garden can be used to extract thermal energy from the soil for space heating purposes.

Iceland Pushes Geothermal Energy Use In Japan

A Japanese macaque swims in a geothermal hot spring in the mountains of Japan. ow ironic that Stefan Larus Stefansson, Ambassador of Iceland to Japan, needs to tell the Japanese how big their potential for geothermal energy actually is, using his own country as an illustration. Interesting detail: most of the geothermal turbines operational in Iceland were made in Japan. 66% of the energy in Iceland comes from geothermal sources. Japan in contrast, despite having the world’s third-largest potential for geothermal energy, built its last geothermal energy plant in 1999, and all research funding from the government ceased in 2003, when the japanese government decided to put most of its cards on nuclear energy. Effectively Japan could replace 25 nuclear power stations with geothermal energy. 92 percent of houses in Iceland are heated by geothermal hot water, and heating prices are the lowest in Northern Europe.


20 GW Geothermal Potential In Japan

Since the Fukushima desaster Japan is looking for alternative ways of generating energy for its economy. Geothermal energy definately is a candidate. Japan has the third largest reserves after Indonesia and the US. Currently Japan generates 535MW of geothermal energy, the eighth producer in the world. That’s 0.2% of Japan’s total output.
