I'm so sick of hearing about wind and solar. The future of renewable energy production... what a load of crap! Our electrical grid requires a stable, steady source of power. Wind and solar are anything but. In order to smooth out the curve of energy production from sources that fluxtuate so wildly, you would need a traditional generating plant. The problem with that is, they don't power-up on a moments notice. It can take a couple of hours to bring a traditional fossil fuel power plant to full capacity. The electrical grid won't tolerate that. You can't keep generating plants running if their power isn't needed; that electricity has to go somewhere.
What we really need is a for energy storage technology to evolve. That's probably our biggest technology shortcoming right now. Everything else has evolved at a Moore's Law pace, but not batteries. Their progress has been a very shallow, linear progression. If we had battery technology that was equivalence to today's processor technology, then wind, solar, hyrid-electric and full electric cars would become practical and truely economical. Until then, our best hope for migrating away from fossil-fuel generating plants is nuclear.
