The popular notion is that Americans are addicted to fossil fuels, but I find that's not true; most people would be happy to power their lives with anything else.

Practically every environmental problem we have can be traced to our addiction to fossil fuels, primarily oil.

We must get rid of fossil fuels by developing injection systems for automobiles, which can run on bio-fuel.

It's as certain that as long as fossil fuels are the cheapest energy, we will just keep burning them.

As long as we're dependent on those fossil fuels, we're dependent on the Middle East. If we are not victims, we're certainly captives.

Despite all the progress climate scientists have made in understanding the risks we run by loading the atmosphere with CO2, the world is still as addicted to fossil fuels as ever.
