A lot of our homes are sourced with hydro-electric and as you say nuclear stuff.
Yep, we could use more in very securred areas.
What do we produce for autos?
Biodiesel for one. Secondly, the "oil from anything" thermal depolymerization process can make up for nearly 100% of our oil requirements just from agricultural waste, landfills, and recycling. That's off the shelf tech - nothing new to invent at all. It only takes political leadership with some integrity - which both parties are sorely lacking in these days. If that leadership doesn't present itself to the public, then the public needs to start actively looking for it while we replace the junk we've got today.
"What do we produce for autos?"
We've got a lot of idle agricultural land reverting back to forest in my part of the country. There are various fuels that can be produced from feedstock. Price to market is the problem, as always. Biodiesel is somewhat more caustic than "fossil fuel" based diesel, but that can be surmounted with retrofitting, about $1,500.00. Or, you can mix the biodiesel with traditional diesel to avoid destroying seals and gaskets, and run it in a standard-issue diesel engine. If you are able and willing to make your own, from used restaurant grease or what have you, you could potentially have more than you could use for about 70 cents per gallon. Supply isn't sufficient for mass adoption though. Methanol is another alternative with a track history. Hate to sound like I agree with ecoweenies on anything, but growing our own fuel sounds like a winner to me, if the economics ever force us to do so.
