How is the USA involved in this?
There was a massive draught which killed the nuclear plants in France, causing them to buy power from Germany at extremely high prices and then at the same time, much less natural gas was being delivered from Russia, and the Russian war on Ukraine caused inflation. And all of that after two years of pandemic now means that many low income families can't afford the rising energy prices.
Obviously, there's many more factors involved, but I don't see the USA in this.
