You can fight the economic forces, but you can't win. The moment you stop pushing against them is the moment the economic reality reasserts itself.

Even if one administration was all in on fossil fuel, and fully opposed to renewables? Best it can do is buy fossil fuels some time, in one country only.

In the meanwhile, renewable power is going to get even cheaper - because there are still improvements to be made and economies of scale to be had in renewables. Fossil fuel power not so much. The economic incentives to abandon fossil fuels would only grow over time.

This is the kind of power the right technology has.
