Wind power just crossed a historic line in the U.K., supplying 32.4% of the country’s electricity in the first quarter of 2023 — narrowly beating gas at 31.7%. It’s the first time on record that wind farms have outpaced gas plants over a full quarter, and renewables together delivered nearly 42% of Britain’s power. Decades of offshore wind investment, falling turbine costs, and the urgency triggered by Europe’s 2022 energy shock all helped get the country here. The lead researcher called it a “genuine milestone,” and rightly so. For climate movements everywhere, it’s quiet proof that energy transitions, however slow and contested, really do arrive — and once the turbines are built, the wind keeps blowing for free.
