"I agree with what I think is the major premise of your question, sir, that we are going to have to create a new conservation ethic in the minds of the American people. and that’s simply why I proposed, 15 months ago, the emergency excise tax on gasoline that I did. I did it as a security measure to be sure, because I would rather see us reduce the consumption of imported oil than have to send American boys to fight in the Persian Gulf. But at the same time, I think it’s going to take a dramatic measure of that kind to convince the American people that we will have to reduce the use of the private automobile. We simply cannot have people sitting one behind the wheel of a car in these long traffic jams going in and out of our great cities. We are going to have to resort to van pooling, to car pooling. We’re going to have to develop better community transportation systems, so that with buses and light rail, we can replace the private automobile in those places where it clearly is not energy-efficient. I think that, with respect to housing, when we are consuming, even though our per capita income today is about the same as that of the Federal Republic of Germany, we are consuming about, by a factor of two, the amount of energy that they consume in that country. Surely, there are things that we can do in the retrofitting, ;n the redesign of our homes, not only of our houses, but of our commercial structures, as well, that will make it possible for us to achieve. According to one study that was published a short time ago - the Harvard Business School study - indicated that just in the commercial sector alone of the economy, we could save between 30% and 40% of the energy that we consume in this country today. So I think, yes, we will have to change in a very appreciable way, some of the lifestyles that we now enjoy."
