A seismic shift from fossil fuels to rising renewables
The previous renewable record was 38.9%, set in the last three months of 2019.
This time last year - in the first quarter of 2019 - renewables generated 35.9% of electricity.
For its share to jump to 47% is incredible, and also reflects how far fossil fuels have fallen.
For context, gas made up 41.8% of the UK's electricity generation in the first quarter of 2019.
Over the same period this year, it was down to 31.4%.
That means gas has lost 25% of its electricity generation share in the space of a year.
Oil's share also fell - and though coal's share increased slightly, it's on an unstoppable downward trajectory more broadly.
Coal production hit a record low in 2020's first quarter. Its total was 26.5% lower than in the first three months of 2019.
Overall, coal produced just 0.87% of the UK's energy - 34 times less than renewables.
