Welsh regions have come first for progress on renewable energy, according to data published by Green Alliance.
The league tables reveal that Gwynedd and Mid Glamorgan are the most improved counties in England and Wales for solar and wind power.
Over the last year, there has been a rise in solar production in Gwynedd, meaning the county beat sunnier areas of the UK to take top place in the solar progress league table.
Top 10 counties for solar:
- East Sussex
- West Sussex
Mid Glamorgan topped the tables for onshore wind power, narrowly ahead of counties in the East Midlands and North West of England.
Onshore wind power is now cheaper than building new gas plants, with solar costs also dropping in recent years. In total, renewable energy provided a quarter of the UK’s electricity last year.
