No, I absolutely refuse. I refuse to such a degree I'm not even going to ask you why I should feel guilty.

I have zero desire to live in that kind of world. The more energy we use the better the world becomes.

We should spend our effort on finding good sources of energy (i.e. cheap, and clean). Not on using less energy.

I don't mind spending some effort on efficiency, if it doesn't impact me (for example more insulation, but zero desire to drive less).
