There are both direct and indirect effects. There's direct employment and then, because those people have jobs, their kids go to school, and they buy groceries, so there's indirect employment.
There's also an issue with net employment. What happens is that, if you save energy, you're going to need fewer people producing what you just saved. So there are fewer people at the power plant and fewer people digging coal. Some of the studies look at a net impact, and the one we did in Ontario for the Ontario Power Authority was a net. Typically, the numbers people tend to come up with range from 7,000 to 9,000 jobs per billion direct, and about the same indirect. You can compare that with different industries. The project that was done at Empire State Building looked at the employment impacts of retrofitting it, which was about 7,000 jobs per billion compared to a coal-fired plant which was about 970, less than 1,000. So it was a 7:1 ratio between a coal-fired plant and energy conservation.
