Clinton, Obama and Biden needed oil to fund their environmental policies of no-drilling and Russia is a giant gas station with a country attached to it.
The US is the largest producer of oil in the world and has been energy independent for a number of years. The US produces about 50 times the oil the EU does. Oil corporations presently import and export oil as part of a larger matrix of market conditions and international relations, not because of necessity due to demand. Unless the US nationalizes the oil/gas industry that is not going to change. The market price for oil is globally set (with localized variables, shipping costs are a factor as well) and no one country's policy can alter it significantly. If the US decides to somehow coerce domestic oil companies to produce more oil and sell on global market they will need to be subsidized to make up for loss of profits in the short term. I say short term because, any drop in market prices will soon result in foreign oil producers lowering production so as to return the market price to a profitable one. Every market expert has said selling more permits on public land will not significantly or lastingly reduce prices for oil. It is a political catch phrase (drill drill drill) that Republicans have used effectively.
Interestingly, the Biden administration banned these oil brokers and corporations from importing oil and coal from Russia in 2022. Before that, the government did not prevent corporate choice to buy from Russia when it resulted in greater profits while simultaneously exporting domestically produced petroleum.
In short, the EU dependence on Russian gas/oil is a serious concern, hence efforts to efforts to find new suppliers and become energy independent through other technologies is vital to the region. There has been significant progress in that direction, but it takes time to eliminate completely. Presently about 1% of oil and 18% of EU gas demand is supplied by Russia. Presently about 20% of EU petroleum is imported from the US. The US does not need Russian oil or gas. Also interesting is the fact that EU brokers presently still purchase Russian oil for reexport to other global markets. So far, the EU has not followed the US in banning the practice.
