Amory Lovins speaks on TED about how to save fuel by improving efficiency. He also touches upon some political issues connected to our use of oil and how improving efficiency can really help. He does so with great insight and humor.

He also sends a harsh warning to the American car industry, it will have to improve efficiency or Americans will start importing efficient cars.

The old story about climate protection is that it's costly or it would've been done already. The new story about climate protection is that it is not costly but profitable. It's cheaper to save fuel than to buy fuel.
