One of the regular intervals of meditation in my life, believe it or not, is in my car.

The two most abundant forms of power on earth are solar and wind, and they're getting cheaper and cheaper.

By 1990 I went back to no gasoline; I was just riding around on my bike, taking the bus. I had a tiny little electric car that didn't go very far or very fast. People thought I'd lost my mind. Even my own family thought I'd lost my mind.

I ride my bike for transportation a great deal - occasionally I ride it for fun. But I also have a generator bike that's hooked up to my solar battery pack, so if I ride 15 minutes hard on my bike, that's enough energy to toast toast, or power my computer.

To build a power plant and run lines to houses, to huts, to anything is a tremendous amount of work...how about...just giving them the service where they need it-on the roof of their hut.

People don't want to change. It's hard for people to change and it's hard for businesses to change. If I was running an oil company, I would be resistant to change too.

Experience nature. Then you know why it's worth protecting.
