That’s the point. Who do we damage? Spreaders of radical Islam like Saudi Arabia and Iran; teetering socialist regimes like Venezuela, etc.
Sounds like a good thing.
It does kill the market for $80-$100/barrel crude oil, that is for sure.
But if the technology evolves to the point that crude oil can be produced profitably for less than $50/barrel (and we may already be at the stage), then the older methods of extraction are going to be bid out of the market, unless they, too, can streamline and update their technology to compete.
And the more that natural gas can displace petroleum as a fuel source, the longer the prices will be constrained on crude oil.
That elusive dream of the “social justice warriors”, that somehow solar power will magically replace all “fossil fuels”, remains just that, an elusive dream. We shall have Thorium-fueled Molten Salt nuclear reactors, or even fusion power generation, long before solar becomes as reliable as “fossil fuel” power generation today.
