I do realize that alternate fuels at this point are not viable for widespread use, but that's why we need to do more research on alt. fuel! If solar or nuclear kicks of really well and becomes super cheap and efficient, then that would be a great thing. We could use cheap, virtually unlimited (for solar, anyway) energy for so much more things and build a better future!

Maybe I'm too optimistic, or just plain delusional, but alternate energy (esp. solar) could be a really great thing given enough research.
