I have heard we were running out of oil forever. My family has worked in the oilfields since its inception. We will run out someday...no question about that! But the same fields are producing here in TX that were producing 50 years ago. Some are producing now that were considered useless in the past. Wells are constantly plugged during "down times" to be saved until prices are brought back up.
We need to conserve...yes. Is "alternative energy" the answer? Maybe, Texas is one of largest wind generation states in the country (so much for us being a bunch of backwards hicks). We may even be a world leader in that area. We have many of them just a few miles from me. I can see them 20 miles away. They are noisy, MESSY, and require constant maintenance. The ones we have here take app 500 gallons of oil to keep them cool, and when they are not turning they still have cooling fans/motors/pumps that use electricity to keep critical components cool. They groan even when the wind is not blowing!!
I have yet to see a "carbon footprint" study on these giants, but the little research I did do on it wasn't overly impressive. The ones making money here are(were) the installers, the landowners and residual support which is massive. Ironically, they are not being installed in my area now...because oil money slowed down and they are not able to fund/cost justify them.
Am I against alternative energy..not at all. I love the concept. But it is my opinion (and it is just that) that the American public is being duped with these things. I guess we have to start somewhere.
Of course , if we were serious, we would turn off the climate control, start riding bicycles and horses again, and well... you get t picture...

Semi related post... my 2 cents worth, maybe less
we're putting them up fast I see wind farms all over since i'm a truck driver, BUT and it's a big one
1, they generate 1.5 MW, pretty anemic by other methods
2, the durn things won't run when it's too cold or too windy
3, the amount of energy that wind /solar supplies is just 4% of the countries requirements
4, give it a decade and BILLIONS of dollars and they might be able supply 10-11%
5, windmills costs 4 times as much as conventional power producers
we need to find/build alternative energy sources but to shut down or severely tax existing conventional power plants is beyond ill-advised. nuclear, coal, hydro, natural gas is what we need right now, in the future who knows what we'll invent.
