Sarduk - HE3 powered reactors will come online within the next 30-40 years. Even with currently available efficiency ratings, 50 tons of HE3 (the moon has about 100,000,000 megatons of the stuff, FYI) could meet the energy needs of the world for a year. Don't you think it'd be more environmentally-friendly to mine 50 tons of material as opposed to thousands of kilometers of solar arrays?
Just because something is non-renewable doesn't automatically make it less friendly. Afterall, the material used in windmills or solar arrays are non-renewable. Conservation > Renewable. It'd be better to use a small, non-renewable amount of product for something that can take care of billions as opposed to a much larger amount of material needed for a renewable source. Even if we did use solar to power everything, the arrays would constantly need replaced by non-renewable materials.
Back from the dead, I'm afraid.
