I think we as Americans know there's a much better alternative than the 17th century practice of burning rocks to power our economy.

Wind has the potential to produce many, many more jobs per kilowatt hour than coal. But the coal industry has tremendous political clout on Capitol Hill because of its alliance with the railroads... and with coal-burning utilities...

Sometimes it's more important to change politicians than light bulbs.

You show me a polluter, I'll show you a subsidy. I'll show you a fat cat using political clout to escape the discipline of the free market and force the public to pay his production costs.

Everyone knows that we're doing a science experiment with Earth. And the No. 1, No. 2, No. 3, No. 4 contributors to it are the mining and burning of coal.

Listen, the environmental movement is not about protecting the fishes and the birds so much as recognizing that nature is the infrastructure of our communities ... If you're saying the values that drive the environmental movement are uncool and antithetical to America, then I would argue just the opposite. If you think being patriotic is not cool, I'd say that's not true either. I'd say the most patriotic thing you can do is to take care of the environment and try to live sustainably.

I was interested in the environment from when I was a little kid. I spent most of my time hunting and fishing and kayaking.
