Ah ha! I knew it! Geothermal can replace nuclear power for Japan. And of course you do have to work on the other side of the equation.. Conservation and efficency.
And did you hear the US is #1 in geothermal energy resources? And it's not being developed? A geothermal plant that's covered up like a cell phone tower shouldn't affect a national park at all. A building or two in a park isn't going to harm anyone or anything. Something has to give.
What are you waiting for Japan? Build it! Expensive? How expensive is dirty nuclear energy? I'd like to see a bar graph that shows the nuclear energy bar shooting up high when all costs and dangers are considered.
