Renewable energies, I think, are a keystone to the future of our country. I think we need to do three critical things: first, invest much more in renewable energy than we have; secondly, conserve, because we waste a lot of our energy today; and third, look at new technologies on how we might be able to gasify coal or move forward with cellulosic ethanol and the like. But we have a huge amount of interest in the U.S. Senate today on moving forward with that kind of strategy to get us off our overdependence on foreign oil.
