France’s state-controlled energy giant EDF has announced it will inject an additional £1.1 billion ($1.5 billion) into the UK’s ambitious Sizewell C nuclear project, deepening its role in one of Britain’s most consequential infrastructure undertakings. The move was unveiled during French President Emmanuel Macron’s state visit to the UK — the first by a European head of state since Brexit — underscoring efforts to rejuvenate Franco-British cooperation in strategic sectors.

The Sizewell C project, located on England’s Suffolk coast, is at the heart of London’s strategy to modernize its power fleet. With many of the UK’s ageing nuclear reactors nearing the end of their operational lives, new builds like Sizewell C are essential to replace retiring capacity, bolster long-term energy security, and anchor Britain’s legally binding commitment to achieve net zero emissions by 2050.

U.S. President Donald Trump has moved aggressively to curtail government support for wind and solar power, ordering federal agencies to tighten rules around tax benefits for renewable energy projects as part of a broader push to prioritize fossil fuels and energy “independence.”

In an executive order issued Monday, Trump directed the Treasury Department and the Interior Department to ramp up enforcement of provisions contained in the recently passed One Big Beautiful Bill Act — a sprawling budget package that Congress approved and Trump signed into law last week. The legislation effectively accelerates the wind-down of federal tax credits for renewable energy developers, slashing incentives that were previously locked in through the next decade.

The sweeping budget package moving through Congress signals a dramatic recalibration of U.S. energy and climate priorities. Passed by the Senate and now under debate in the House of Representatives, the “One, Big Beautiful Bill” slashes funding for clean energy initiatives, weakens incentives for wind and solar, and paves the way for a major resurgence of fossil fuel production—both onshore and offshore.

It marks a striking pivot from the climate-focused policies of the Biden era to a blueprint that more closely aligns with former President Donald Trump’s vision of U.S. energy dominance. At the heart of the bill is a sharp curtailment of the tax credits that have underpinned America’s booming wind and solar sectors.
