geothermal energy

I think Japan should build some kind of geothermal power station. This artical saids that Japan has the potential of producing around 24 million kilowatts with the geothermal electrical resource alone. I think Japan should adjust geothermal power because of this reason. Also, this article saids that if we put the geothermal hot water into space heating or free up the electricity for domestic sales, we could be doubling that figure. This fact very surprised me and I don't know why Japan shoudn't do these things. Of course, there might be many problems like the budget but I think all prefectures in Japan should challenge and try. It is a good opportunity to move to geothermal power plant instead of nuclear power plant since we experienced Great East Japan Earthquake on 3/11. I think Japan should make actions.
