Wade Allison has done a short but devastating analysis for the GWPF. The take home message is that the energy contained in the wind is diabolically more erratic than most people realize. It’s just basic physics and almost no one in politics seems able to comprehend just how impossible these numbers are. If only they would “follow the science” eh?

The exponential death of affordable electricity

It’s just physics. The power of the blowing wind increases by the speed of those particles cubed which produces a twin engineering nightmare. If the wind doubles in speed, the energy goes up by a factor of 8 (or 2 × 2 × 2, and we need to spell it out), and if it slows by half, the energy drops eight-fold. It’s bad both ways. At high speeds, the mechanical engineers have to turn off the turbines to protect them, and at low speeds the electrical engineers have to ramp up power stations that may not exist, or pray to Gaia for batteries that will never exist.

Allison has a graph showing the total output of all the wind turbines in the UK and Europe […]
