- CLM-1431 In the first week of November 2024 the wind was light: wind made a tenth of Britain's electricity supply, against almost 30 per cent over the year, and gas made half.
- CLM-1449 Britain's solar panels make far less power in winter. In December 2024 they made about a ninth as much as in June. On the worst day of 2024, in late November, they made less than a seventieth of what they made on the best day, in early June. Even within December, the worst day gave about an eighth of the best.
