Wind Power Reassessed: A review of the UK wind resource for electricity generation
The UK wind debate assumes that wind farms operate at roughly their average output most of the time. According to Dr. Capell Aris’ new paper produced in concert with the Scientific Alliance this is not true. Power comes only extremely intermittently and variably and there are long periods of negligible efficiency in the long winter months when power is most needed. A 10GW wind fleet would need approximately 9.5GW of fossil capacity to guarantee its output.
