Pledge: clean sources make 95% of Great Britain's electricity by 2030. Starting from 60.5% in 2023, the straight path needed 70.4% by now.

What it means: low-carbon means renewables plus nuclear. The figure is for the whole UK and the latest year is provisional, while the target is for Great Britain in a typical weather year, so treat the gap as a guide.
