I think electric cars can help save Detroit. They reflect good decision-making, and there has been bad decision making in the auto industry for so long, in my view.

There are not a ton of people buying cars - cars are expensive. So people usually go for the cheapest car they can get. And if the price of gasoline falls again, it makes the savings that you get with an electric car harder to realize.

I think China is set up to surpass the US on the even more critical industry of green power.

Solar, for example - which has typically been thought of as so expensive - is cheap when compared with, for example, the cost of cleaning up the Fukushima nuclear disaster and the Gulf.

I like to take folks back to the turn of the century when people said 'gas cars can never replace horses because you can feed horses at your house, you get along with them, they're nice.'

Resistance to change is always the biggest obstacle.
