I think the answer is both yes and no. Yes in the sense that there are clear areas where we can greatly reduce energy consumption, and I pointed them out. On the other hand, we have to be honest and understand that on the supply side, when we talk about new energy supplies, there are really only half a dozen kinds of energy supplies. We can tick them off on one hand practically.
On the demand side, to reduce energy consumption, it's an extraordinary complex collection of activities, and each activity has to be addressed individually. Some of them have tremendous savings potential simply with a technical fix. Sometimes we can even bypass some of the obstacles and save energy in ways that we might not expect. For example, we could try to make gas and electric ovens more energy efficient, but then we come around and invent a microwave oven that cooks in a completely different way. So there are completely new kinds of solutions to problems that we haven't even seen, and those will often yield the greatest savings. It's very difficult to figure out how to promote those.
In terms of telling the consumers what to do, yes, there will always be a list of the top 10 or top 20 most important measures, but the fact of the matter is that each household, each store, each factory will have an element of its own uniqueness that we have to take into account in order to save energy and to save money in those places.
