None of which is going to immediately bring gas prices down, and none of which (excepting nuclear) is going to give us more nonrenewable resources in the end. The idea of power itself needs to be rethought.
But EVERY power source will have its downfalls. Nuclear is AMAZING, but you have to figure out what to do with the byproducts. Hydrogen is AWESOME, but I can forsee in another 100 years people complaining about too much water or something. Wind and solar are renewable in a sense, but how will huge wind and solar farms affect the climate and weather.
When people say nothing can happen right away, thats bullshit. E85 happened right away. People saw potential to make a product they have selling at say $1 a bushel sell for $10 a bushel.
I mean... even if people cycled everywhere, you have to feed them and deal with their waste. Its a cycle. Its just about what the best option is.
Hydrogen. Its the wave of the future.
