There ARE things that can be done NOW:

1. Carpooling.
2. Plan your driving trips so you make fewer single-purpose ones.
3. Walk or bike where/when you can.
4. Take the bus, train, or other form of mass transit.
5. Turn the thermostat down in winter and up in summer.
6. When you drive be sure that you car is in top condition and the tires properly inflated.
7. Buy the vehicle you need: if you don't NEED a Hummer, don't buy one.
8. Don't buy an ATV, snow machine, or other "recreational" toy unless you need it on the farm or ranch or whatever.
9. Don't buy an RV unless you need it, and then don't buy more than you need.
10. Support expanded rail service for both freight and passengers.

Of course, all of this was said back in the '70s, during the last "oil crisis".....
