One thing we can all do is contact our senators and representatives and tell them to stop subsidizing ethanol!!! Tell them we don't want federal regulations about what we have to use for a fuel source (or at least to pick a good one to shove down our throats).
It's debatable whether you even get the same energy out of corn ethanol that you put into making it... even if we break even, what's the point? It has artificially driven up the price of corn (we're affected in a big way here in Missouri), and also drives up the cost of gasoline.
If you've seen the news stories about food riots, you can thank our wise leaders for the same reason... there is a ton of money to be made by switching fields over from wheat or other food crops to grow lower grade corn. They get a huge tax break, a subsidy, and a few other little perks.
Also, tell the congressmen that it's time to use our natural resources! There is a section of Alaska that was specifically set up as a drilling site, but they refuse to allow it. There might be a one-eyed spotted field mouse out there somewhere.
We can also use the oil shale out west- in the 70s it just wasn't practical to refine it (costs about $40 per barrel to get out), but heck, even if it were to cost $60 per barrel it would be worth it now!
Becoming energy-independent is vital for this country. There are a lot of bad people that we stay beholden to because we don't dare cut off our supply. I'm all for developing new technologies as long as we don't regulate the crap out of the old ones- especially if it's for Al-Gore-scam reasons.
