Stefan Larus Stefansson, Iceland’s ambassador to Japan, recently gave a lecture in Tokyo about the very high geothermal potential in Japan. He said that if Japan were to invest in fully realizing its geothermal potential, the country could replace 25 nuclear reactors.
He used his home country as an example of geothermal success because about two-thirds of the country’s energy comes from this renewable, stable source. Japan has the world’s third-highest geothermal potential but has not been pursuing its development nearly as much as it could be.
Ironically, it was the nation’s focus on nuclear power that caused this lack of attention for geothermal development. It isn’t as if Japan is missing the technical knowledge required for geothermal installations either. They actually make the turbines Iceland uses for its geothermal plants. As a percentage of total power, developing countries like Kenya and E
