Oh man, where should I start on this?
First off, 'global warming' has been going on since the last ice age! It is NOT caused by Man, at it as most been fractionally sped up by Man.
As far as Nuclear goes, the waste issue is the problem. All the nuclear waste in the world comes to the USA for safe storage. The USA also helped dispose of substantial nuclear devices from the former Soviet Union, recycling the weapons into fuel for nuclear plants. Nobody's sure what to do with all the nuclear waste, current plans are deep underground storage.
On BioDiesel: It is renewable and sustainable indefinately. Vast amounts of farmland are under US government subsidy to NOT be used for anything every year! Corn keeps being touted, anybody that thinks corn will bet he primary source for BioDiesel or Ethanol (for E85) obviously doesn't know WTF they're talking about. There are a lot of much more efficient oil products than corn, there are better ethanol base products (brazil uses sugar beets for example).
Then there are the oil algae, this is rapidly-growing algae that have a high percentage of suitable oil AND the algae are fantastic at treating sewage to the point that it is nearly pure enough to be consumed by humans at the final stages! win-win!
Please educate yourself fully and don't believe just propaganda from one side or the other. I am far from a Green Party type yet I generally know environmental issues than many environmental activists do. I am actually a right-leaning ethical capitalist that tries to made educated decisions and educate others.
