Jake,
Am sort of surprised you see the dependence on Russian oil and gas as an impediment. Markets are not fixed. It can change. In fact the threat by Nato or USA might entail going elsewhere to purchase oil and gas.
Europe is starting to switch suppliers, but they had to have their heads put over a barrel by Putin before they would change, when they could have been doing more to diversify their supply before then.
The U.S. has lots of restrictions that keep us from our full energy independence potential, so that also limits what we could supply to Europe.
Moreover, Europeans like the U.S. increasingly, are becoming enthralled with Net Zero pipe dreams of supplying their energy with wind and solar, and subsidizing those projects works against them exploring for more petro options, too.
Markers can only change when freed up to do so.
