Money - The new religion. Just as bonkers as the old ones, when it comes to a model for running a society with any sort of future.
Energy - There's no one solution and you mix it up accordingly. If you're in the sun - solar. If you're in the wind?... You take the locale into consideration. Since we're an island nation, the tides are the bleeding obvious answer. FFS we've had missiles capable of being launched from submarines, that plan their own route over thousands of miles and taking evasive action if they're detected for decades now. In comparison, devices like this..
... which the Japanese are funding now, are child's play. It's just that they're expensive to develop in the short term and don't promise as much profit as hydrocarbons in the medium term. They don't give a **** about the long term, see 'Money' above.
Nuclear could be good, it needs more work on its waste products. Thorium is a massive step in the right direction with decay time, but more steps need to made.
In a perfect world the existing nuclear nations would club together for the greater good. Go somewhere remote, pool minds and reduce parallel unnecessary research.
Another factor to take into consideration before completely poo pooing the Greens is the media slant. The vast majority of the media, beyond the obvious buffoonery of Fox and the Mail, are controlled by folks who do not want you to vote Green.
Now all go watch 'Baraka', peruse a respected scientific journal or two and buy just one copy of 'Private Eye' - especially if you haven't before.
I wanted spaceships from the future, and we got hedge funds.
