Xmas Eve Renewables:-
UK's renewable utilisation factor is 36.7%.
Wind: 49.7% capacity factor (15.9 GW from 32 GW installed)
Solar: 14.7% capacity factor (2.8 GW from 19 GW installed)
This means that despite having 51 GW of installed renewable capacity, only 18.7 GW is actually being generated

2025 First Three Quarters
Based on government Energy Trends data covering Jan-Sept 2025 compared to the same period in 2024:
Wind generation up 7%, solar up 26%, while gas rose 10% due to record-low nuclear output. Renewables reached 54.7% of total electricity generation.
