I am not going to sit here in denial about the future supply of oil. It is running out. However, until it does run out, we do not need to continue to provide traditional enemies and/or unstable countries with strategic advantages against us (militarily and economically).
We currently own enough resources to materially boost our economy while materially weakening foreign economies. Yet, we are handcuffing ourselves for the sake of asthetics. That just seems absolutely asinine to me.
I would love to see the US make the break through on the next great fuel/energy. However, I do not want us to panic, rush, and be legislated into depending on a far less efficient energy source, while the rest of the world continues using oil.
I would love to see large firms invest R&D into hydrogen cells, engines that run on nuclear technology (if, and that is still a big if, the Soviets could (no definite proof) dwindle down nuclear weapons to fit in suitcases, then certainly we can fit nuclear energy into the size of an engine block), and/or maybe one day cold fusion.
However, driving up the cost of staple food items (corn and sugar) in order to crank out a gasoline that is 20% less effective at 20% less cost is backwards. Especially when one considers that by driving up the cost of staple items, you are driving down the value of the dollar.
Also, if the argument is for green reasons, I do not want to see electronic cars. Most Americans are getting their electricity through coal (as well are most worldwide). I would argue that it is less environmentally friendly than the exhaust from a diesel engine. On top of that, your freedom to drive anywhere is reduced when you have an electric car...therefore, it is less efficient for the average American.
