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.

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.

I bought my first electric car in 1970. Its top speed was 15 mph and it had just a 15 mile range - it was essentially a golf cart with a windshield wiper and a horn.

I'm not a wealthy person because I was never a star. I was a working actor and a supporting actor.

I've been in movies with Meryl Streep, Jack Nicholson - but I was on 'The Simpsons,' and finally, in the eyes of my children, I was a star.

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

To be a modern person in 2012, you are often required to have some electronics in your life. And I do. I try to put that phone down, put the computer away, and get out there and hike in the woods; feel it in my feet, feel it in my hands; get out in the garden and feel the soil under my fingers, my fingertips and my fingernails. I try to be involved in nature in a very tactile way. I think that's important.
