Nuclear and gas “are the only reliable” ways of ensuring electricity supply given the intermittency of windfarms, the GMB union has said.

In a statement on 7 June, the GMB said that since June last year there had been over 1.5 months of low wind days—when connected wind turbines produced 10% or less of installed wind capacity—and that the renewables industry could not “shrug their shoulders” at the issue. The union said it recognised that in the long term “sensibly sourced” renewable energy “makes sense, but in the real world” reliable sources of energy were required.

Justin Bowden, GMB national secretary, said: “[…] Until there is a scientific breakthrough on carbon capture or solar storage, then nuclear and gas are the only reliable shows in town which those advocating a renewable energy only policy have to accept.”
