The news: In the third quarter of this year 40% of the UK’s electricity came from renewables like wind, biomass, and solar, while fossil fuels—virtually all gas in the UK's case—made up 39%, according to climate change analysts Carbon Brief. The remaining 21% mostly came from nuclear. It’s the first time this has happened since the UK’s first power plant fired up in 1882.

Why? The milestone is largely down to a few new offshore wind farms that came online from July to September this year. The wind farm industry in the UK is in the midst of a boost, as turbines become bigger and more efficient, making projects easier to justify commercially.

The global context: The country has made rapid progress considering fossil fuels made up four-fifths of its electricity just a decade ago. However, others are further ahead still. Germany passed the same milestone as the UK last year, while Sweden met it seven years ago. The power grids in Iceland, Norway, and Costa Rica run almost entirely on renewable energy already.

However: In the grand scheme of things, three countries matter most: China, the US, and India. Between them, they account for about half of all global carbon emissions. China’s share of renewables in its power-generation mix is almost 27%. In the US it’s just 18%.
