We are amazingly wasteful regarding energy. In all aspects of our society, energy is so cheap, we don't even consider it - think of the open refrigerators and freezers in supermarkets. Energy efficiency is the cheapest 'source' of energy and can be as low as 3cents/kWhr. I think energy demand is viscous - elastic but slow. It takes time to adjust to a more energy efficient lifestyle. Awareness, new products, and energy effcient technologies have to be developed and deployed. For example, I'd like to buy a Prius, but my present car is 3 years old and fine. It doesn't make financial sense to trade. But my next car in three years will be a hybrid. When natural gas prices go up, watercooler talk will start to center on insulating hot water pipes, changing HVAC air filters, replacing windows with highly insulating windows, making sure the refrigerator coils are dust free.

Fast changes in energy price force consumers to eat the price before any adaptation, reducing other consumption, thus slowing the economy. The more slowly energy costs increase, the more likely we can adapt and still have a good economy.

Henry, if you're current car is three years old (we're in the same boat in a one car household with my wife's car being 3 years old), by the time you're ready to buy a new car, you just might be buying an all electric model instead of a gasoline hybrid. So look at the bright side, you might get to leap frog some technology.
Wholesale electricity from nuclear power plants in California is 2.8 cents a kW-hr.
