Quick: what was the number one source of electricity production in the U.S. during the first half of 2017? If you answered renewable energy, you are wrong by a mile. If you answered natural gas, you were wrong by a tiny amount.

Let’s stretch our imaginations for a moment and assume that the left is right that global warming will bring apocalyptic warming by the end of the century and that the only way to save the planet from extinction is to stop using fossil fuels right now. That will be a spectacular disruption to world economic prosperity because cheap fossil fuels account for about two-thirds of all electric power generation and at least 80 percent of transportation fuel.
