one of the most publicized mega-solar projects, and it is going nowhere.
But Japan has very little sunlight, not particularly terrific wind conditions and no terrestrial biomass potential. Geothermal is good for onsens, but their heat source is not too high. I asked my "friends" in Japan to set Mr. Son straight. Japan's sun is not their answer. Their only hope is the ocean. How many major sustainable ocean energy projects have subsequently been announced? ZERO!!!!
Hydrogen has been suggested, and I co-authored a paper on these prospects, linked with the ocean. But this deviation is something for the 22nd century. Solar power from space? Japan is ahead of the curve in this option, but the reality is fanciful at best, and really expensive.
So what is Japan doing? Well, they are importing more fossil fuels and floundering.
What is their real future? The ocean! Start with Shimizu's Green Float:
