If we cant get food right, what the hell are we up to!?!<br /><br />If nuclear has to be part of the mix to help "bridge the gap" we can't do it like we have in the past, the F-T process amongst others could be used to create, water, electricity, liquid fuel, and possibly hydrogen for fuel cells, from sea water. Not green, but not ancient carbon based, and a path to sustainability.

You need a primary source - like, first! Guess what that is?<br /><br />Hydro is good. Need min 'drop' in water levels for efficiency. On-shore wind is also good. Off-shore - not so good!<br /><br />Big, big, like in really BIG predicament, is your min electricity Base Load requirement; ie; MW per 24/366!

Wind/Solar require large land area's which is in very short supply in Japan. The population density means that there is very little "roof" area per person to pursue solar on a individual level. Bio Fuel, except a small amount that could be gained from vegetable waste is also a non-starter due to arable land limitations. Geo-thermal is possible but there is evidence that large-scale exploitation may increase the likelihood of earthquakes -- not something the Japanese are willing to risk I bet. It all comes down to land area per-capita in Japan which is a serious limitation to most renewable energy sources.<br /><br />Short of sending thier economy back to pre-1850 times, I don't see how they could have an energy mix much different than what they have -- with today's technology."<br /><br />Thanks a lot.camabronhttps://www.blogger.com/profile/10024146459457965038noreply@blogger.comtag:blogger.com,1999:blog-4102429195693595750.post-28699713357204381982011-03-29T16:39:00.253+03:002011-03-29T16:39:00.253+03:00Portugal is another country with great green infra...Portugal is another country with great green infrastructure.Chrishttps://www.blogger.com/profile/13217554275140560787noreply@blogger.comtag:blogger.com,1999:blog-4102429195693595750.post-60984862727013356522011-03-29T15:10:01.633+03:002011-03-29T15:10:01.633+03:00BTW: Baden-Württemberg is one of the powerhouses o...BTW: Baden-Württemberg is one of the powerhouses of Germany.
