I don't know what he is thinking. I know what he says. And what he says shows that he has no clue about the energy problem.

Unless we have an energy problem, which is precisely what he does not seem to grasp. People who are concerned about the energy consumptions are concerned precisely because it is a problem. And if we are really generous with his answer and start replacing what he said by what we want to believe he said, then the conclusion is that he is very naive and doesn't understand the problem at all. And that's the generous case where we completely ignore what he said.
