In the last year we as a country generated 28GW (not GWh there is a difference) of power from gas generation plants.We're talking about electricity produced from gas. If we were talking about electricity generated from all sources then 28GW is about right.
In contrast 5 May 2022 holds the record for the maximum amount of wind power generation, at 19.9 GW.
In 2020 renewables accounted for more than 43.1% of the UK's total electricity generated, at 312 terawatt hours (TWh). This outstripped fossil fuels over the course of a year, for the first time in the nation’s history.
