We went to see the war memorial at the former RAF Bradwell in Essex. The site became a nuclear power station after the war. It was the first in the UK to be decommissioned, being turned off in 1962. It generated 242MW across two units. There are now onshore wind farms that can generate as much as one of those units, but not with the continuity or compactness of supply.
