JoulesBurn,
There is nothing about California that screams efficiency.

See this post about the energy efficiency measures in California. It also helps to have high electricity prices, but most of these measures cost 3-4 cents /kWh saved, a lot less than anyone pays in US.

The US and Europe have outsourced much of their energy-intensive industry, providing services in return.

I maintain that nearly all energy is imported into US as oil, even motor vehicle imports use a lot more energy in their life-time than embodied in manufacturing. In US 100% of vehicle steel is recycled, most of the energy in manufacturing vehicles in US(or Japan) is used by the employees at car assembly plants going to and from work and energy used at home. none the less >75% of the energy used by a car will be from gasoline and the energy used to refine transport and sell that 7,500 gallons of gasoline used over 15 years.

China's energy usage has been increasing dramatically along with their exports and GDP, and the majority of that is industrial usage.

Automobiles are a special case, since they directly consume a huge amount of energy in use.
