Now, this is a big, complex issue, and a lot to absorb, but the thumbnail is this: Rising nationalism in Europe is driven in part by frustration over rising energy costs (as well as things like unchecked immigration) and those rising energy costs are in large part due to net-zero schemes to appease climate activists. Britain has gone all-in for renewables, but the renewables aren't consistent, and when the wind isn't blowing, the United Kingdom has been relying on the expensive proposition of starting up natural-gas-powered electrical plants - using Norwegian natural gas. Their backup, incidentally, is gas imported from the United States, and President Trump is planning to ramp up production, but he's also likely to meet American consumer and industrial needs over exports. Interestingly, in the article linked above, "The Telegraph," an outlet not terribly friendly to President Trump, has actually given him credit for doing what's right by America first.
