Too much to quote! I think everyone has good points and everyone is missing some points WHICH (not witch, dude) needs to be addressed:
1) Oil is not only used to make our machines go vroom vroom; oil is used to make most plastics and lubricants (hu-hu, you said lubricants) and more.
2) Oil powers our economy; if the military has it and we don't: it doesn't matter. We buy all the bullets, armour, etc and without an economy EVERYTHING shuts down even if every fighter, bomber, tank, ship and rocket has gas in its tank.
Two things spark invention: necessity and boredom. I am sure many scientists have been bored enough to think of some cool energy alternatives. But even if they have them, releasing them now would destroy our economy. The conspiracy theorist in my would say that a new technology will 'spring' up when it is economically feasible. But who knows.
Sorry about the bail out on the hydrogen fusion research: we're too busy playing 'world cop' to care. Besides, we got all the energy we need in Iraq-provided by our friendly neighboorhood oil company and or course Haliburten (sp?)
The upside to all this crap? The US's position is weakening and we can finally go back to being Americans once the EU starts running things...unless you mess with our crack, I mean oil.
Now, lets get back on topic: Oil vs the environment: your position?
