The UK is gambling on wind in the future of renewables - but as we're seeing, having the turbines doesn't make them turn.
Yet as people settled down to work on Monday morning, gas power stations had been ramped up, producing 61% of our electricity.This snapshot is unusual, but it does show the limitations of renewable energy in some weather conditions.Scientists working for the United Nations' intergovernmental panel on climate change have looked at what could happen to wind speeds in future.
It's called global stilling. And it's caused by the rapid warming of the Arctic, which is narrowing the temperature difference with the tropics, a gap that drives wind. In the UK, the average wind speed is expected to drop by 2% to 3% by 2050, and 10% by the end of the century.We have 14.2GW of onshore wind turbines, with another 13.7GW offshore.to 50GW by 2030, and to turn off gas and coal power stations by 2035.Although the government also plans to expand nuclear energy to 24GW by 2050, up from about 6GW now, that would not fill the gap left by the lack of wind.
We will need to find some way of storing vast amounts of energy, invest in new sources, such as tidal power, or import much more through long distance cables.
