I commute to work, but cannot carpool, as I am called out from my office to many places every day. I never know what each day will bring. So that won't work for me, unfortunately.
I think it's as simple as the law of supply and demand, or more accurately, the public perception thereof. LIT is right about the oil reserves. Certainly the supply of oil is finite, but it will indeed last quite a long while. There is enough known oil in Alaska to make the USA self sufficient, but for environmental reasons, some are afraid to get it. The northeast coast has vast reserves that can't be touched for political reasons. New technology is making wells productive again on the Gulf Coast, and I could go on. Basically, for the forseeable future, there is plenty of oil. Those are the facts. To alleviate the crisis we need the following:
1. A government who will bring sanity into this energy chaos, and stop the big oil companies from raping the people. I, for one, am tired of not being able to afford groceries every time someone in Pakistan or Iran sneezes funny. None of this has ever caused a shortage of supply, though we pay as if it did.
2. A government who will actively support developing our own oil assets. Environmentally friendly ways of producing oil and gas exist now, so why are we buying foreign?
3. Alternative forms of energy must be developed that will bring an end to the excessive need for petrolium. Wind power needs to be expanded. Solar is OK for residential supplementation. Ethanol production should be greatly expanded, though at current, it takes a lot of energy just to produce ethaol, so we need better technology. Nuclear energy needs to make a comeback. It has proven itself to be safe and effective. Some of the experiments with wave motion sound promising to me. Of course, fuel cells are awesome and totally pollution free, though there needs to be a better way to produce cheap hydrogen. Hybrid cars need to be better and more available to the public, meaning that the initial cost and the maintenance costs need to be as good as or better than a traditional gasoline vehicle.
4. If we could do the above, our need for oil would run short way before the supply did.
If we do not stop the lunacy we are certainly going to end up in recession. There is not enough extra money to absorb the steep jump in transportation cost.
