So you want to save the planet? What should you consider first?

Because:

The benefits to consumers from energy efficiency investments are, if anything, likely to compound. Once you hit the payback period, energy efficiency is like a cash cow -- it just keeps saving and saving. (And saving.)

And we are on the track to doing something about those greenhouse gases.

* Here's what Cheney said during the California energy crisis:

"What's happened in California, I would argue, is they've taken the route of saying, 'Well, we can conserve our way out of the problem. All we have to do is conserve; we don't have to produce any more power.'

"So they haven't built any electric power plants in the last 10 years in California, and today they've got rolling blackouts, because they don't have enough electricity; they've got rising prices; they've got a whole complex of problems that are caused by relying only on conservation and not doing anything about the supply side of the equation."
