In a perfect world, people would give up some "luxuries" in order to help this situation. Fact is Americans are a lot of the problem. Other developing nations see what we have and will go to any length to have it themselves, no matter the cost and I'm not talking money. We need to lead by example. I don't know what the answer is to vehicles. Ethanol is a time waster and we'll have fuel for our cars but no food on the table. Hydrogen is easily made by natural gas and still too expensive to readily implement. Hybrids may be a start but they have a hell of a long way to go before they'll do anything. I saw a hybrid Suburban (full-size SUV for those who don't know) that the electric motor only went up to 17mph. I can imagine it cutting down on emissions since it takes a lot of energy to change the state of any object but 17mph? That's ridiculous. Couldn't the engineers gotten it to maybe 20 or 25 for people driving in residential areas? I mean... come on. Ill-purposed residential/commute vehicles aside (SUV's, Trucks), there have been several fully electric cars that were produced both by companies and individual parties. If they can make them happen then what's the problem? Vehicles that run further than the average suburban (not car) work commute that have 0 emissions (from the car, electricity production will be covered later) that you can charge at home? Maybe the government could offer a tax break for businesses to install charging stations in the parking lot.
Electricity production (told you I'd get to it

) is another hard subject. We all over-use electricity when we don't have to and I believe that problem should be solved before trying to get an alternative source of electricity because I believe we can reduce oil/coal/nuclear usage more by reducing our usage than researching or implementing an alternative form of electricity.
I'm kinda spent as far as providing an argument on this subject right now and would like to see others getting involved so I'll sit back a few posts.
