From the tone, my impression was he was not just playing devil's advocate to the mayor's call for less consumption. He really meant it.

Unfortunately the tree-hugger energy reduction narrative many people have in their head is pretty similar to what our disaster of a Vice-President said: "Reducing Energy Consumption may be a matter of personal virtue, but it's not a basis for public policy". However even personal virtue is considered relevant by leaders and policy makers anymore. We need to activate that personal virtue within each person, who would do something if they thought it really mattered and would make a difference and encourage that impluse at every decision. And why is it wrong for self-interested people to be educated about how they can save money on their growing electric bills?

At least Bloomberg is someone who has a chance in hell of convincing people that the Cheney position is idiotic. He's important enough a leader that people might listen to him.
