You can't just do one of the things, because it won't be enough to combat the climate change that we're already starting to experience. It will only get worse.

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've lived a slower and less expensive life going off the grid, and I'm happier because of it.

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

My favorite form of transportation is walking. I live in a neighborhood where you can walk to restaurants, banks, and shops.

I'm a strong proponent of green tech for anyone who can afford it, having spent the last 40 years working toward achieving a smaller and smaller eco-impact for myself.

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.
