The answer is definitely to use less oil. The USA is responsible for more than 20% of the world greenhouse gas production. Use smaller cars, use your legs, car share to work, use public transport, eat less processed food, turn down your heating or your air conditioning a couple of degrees. Just do something! Design your towns and cities to be more pedestrian and public transport friendly. I have a friend in Nashville who finds it physically impossible get to the mall unless it's by car, because she has to cross a busy freeway. I'm really not anti-USA, but you've all been using far too much energy for far too long and payback time is closer than you think. Above all elect a decent damn President with vision!
