I think everyone around the world is realising that we need to find alternate solutions for the current and future energy crisis.
There has been too little spent on research into renewable energy sources and too much reliance on oil supplies , that is now kicking everyones arse. The only realistic future has to be one of solar and nuclear power .
There are those who believe that biofuel is the way to go but that simply won't work because of the scale of growing that would be needed. Imagine how many fields you would need to supply America with biofuel , fields that currently grow crops for consumption would be given over to Rape to make fuel , this would affect the food supply chain on a massive scale.
