there is a LOT of misinformation in this thread. a whole lot.
"Hybrid cars may (or may not) be an improvement on gas-guzzlers"
that's a pretty unsupported assertion. A Hybrid never gets plugged into any grid. The gas engine produces electricty as a by product, and the car simply uses it to power a motor. You now need a smaller gas engine, and a small electric motor. Car goes faster, with less gas needed.
Hydrogen takes more energy to make than it holds.
Imagine $2 Billion/week working on making our country smarter, more efficent, and more competitive against the world.
Nuclear Power might be a nice place to start. Coal Plants produce more radiation than any Nuclear plant ever could, and the Coal plants spit it all into the air. (do research before you disagree with that claim, it's scientific fact)
How bought the government spending money to inscrease the efficency of PV
It can be done, but since the CONSUMER won't do it until it hurts their paycheck (hence gas prices going way up is GREAT for this country) maybe the government can take the lead (ha...) and invest in our future at home.
