We all know the USA also has rich oil reserves, but Big Oil cannot and refused to produce more oil. Oil giants in the USA are not going to invest huge sums of money to extract more oil to flood the market. They prefer to keep production low, keep prices high and reap all the profits. Europe is a gold mine for USA Big Oil today. The USA Government could do nothing to help Europe. Otherwise Biden would not have to crawl to MBS to beg for more oil, and even feigning to cosy up to Maduro, backtracking over some of the sanctions against Venezuela. Shameless doggie?
Big Oil in the USA knows that even if they flood the world with more oil, cutting their noses to spite their faces, OPEC+ is not going to stand by and see oil prices falling and affecting their revenue. OPEC+ will likely cut production to compensate and USA oil reserves will be exhausted much faster. Oil is not an inexhaustible resource. It is a security issue that the USA Government is not willing to take as they prefer to exhaust Middle Eastern and other country's oil reserves first. The USA Government therefore will do nothing about this. After all, the US$ hegemony is all backed by oil.
The energy problem is one that Europe cannot solve today, tommorrow or thereafter. Even going back to nuclear energy needs the raw materials which Russia controls in a big way. Going back to coal is not a solution in the long term, although they are back at it. Europe is toast and the only way back is to back down to Russia. But Russia today is in a stronger position and has more bargaining power than two years ago. Russia will probably not sell energy as cheaply to Europe as before. We still read about the hubris on some social media sites claiming that Russia is collapsing and Putin is 'Finnish' from Finland. No he is 100% Russian. LOL
We can see that Russia takes pains to plan its move well before the shit hits the fan. Russia had already been given eight long years to engage with China, building 'Power of Siberia' pipeline towards China, doing more trade with China and building alliance and co-operation with China. A second pipeline, 'Power of Siberia 2' is under construction, also leading to China. There are also massive plans to build highways linking China and Russia.
All energy sales previously to Europe will now mostly be taken up by China, India and of all countries, Saudi Arabia. Does the oil price cap work? Well, just look at oil prices today.
