Energy sustainability is not about resource availability and pollution. Capitalism and human ingenuity have already addressed “sustainability” in these regards, if the statistics are to be believed.
The real sustainability challenge and threat concerns government intervention in the name of “sustainability,” because it is political and bureaucratic intervention that reduces the availability, reliability and affordability of energy. The real sustainability challenge is also about overcoming the forces of nature, via with ever stronger energy infrastructure around the world. That is a job for capitalism, not central planning.
