The actual solution for European countries is for them to find their own sources of gas, which in most of them are already below their feet. Poland, Ukraine, and UK, for instance, have extensive shale gas fields.
They’re not really dependent on Gazprom. Gas is fungible and can be bought from any producer in the world. Gazprom just provides the cheapest gas. They are free to pay higher prices from other sources, and will undoubtedly do so if they truly fear a Russian invasion. As of now, they are betting that Russian territorial ambitions are confined to Ukraine.

Which means that we headed for a disaster as the Democrats and the EPA slowly kill off coal and nat gas from fracking.
It is very possible that we will be left with only solar and wind to charge our electric cars. Good luck with that.
Why are we restricting our own sales on anything in an economic downturn?
