I agree with the sentiment, but not the conclusion. The reason we have to reduce the rate of fossil fuel consumption as much as possible is that it will buy time to develop and commission realistic alternative energy sources, the most important of which will probably be fusion based. That might take 50, 100, 150 years, who knows. In the meanwhile we need to survive on existing technologies and resources, and save energy wherever possible, every last one of us. We could start by closing down the PF.
