Heatwaves across Europe have created a ‘heat dome’ of high atmospheric pressure, and unusually warm sea temperatures. This Hitzeflaute – a period of high temperature and little or no wind – is even more intense and persistent than in previous years and their increasing frequency and duration is reducing wind speeds, further tightening power supply just as demand surges for air-conditioning. Wind developers and power producers should brace themselves for turbulence over the coming years as the world heats up.
