Or cars that get better gas mileage and other conservation efforts. Look at what happened when demand went down by just a few percent. Imagine if people continued to make efforts to conserve fuel, like combine trips to keep the engine warm (engines are more efficient when they are warm), keep tires inflated, plan routes to reduce idling in traffic, take public transportation (where available), etc.
Why should be hostage to global warming and governments with certain ethical issues?
Why not do the smart thing and conserve energy and use renewable resources?
