Wind turbines

To meet the Conservatives’ net-zero emissions target, the UK will need around 40GW of new, low-carbon baseload generation by 2050. Technology undoubtedly holds the answer to achieving that. But it is no use setting our hopes on fashionable technologies simply for their appeal.
Sadly, however, the Government’s latest decision to onshore wind seems to fall into this trap. It is welcome that the plans will still give local people a strong say in new development decisions. Indeed, they should have the final say. But the problems of wind turbines go far their being mere eyesores.
Wind turbines are already close to their maximum theoretical efficiency – the Betz limit – and their effectiveness will always be determined by the wind available. Given that, for wind turbines to supply only the annual global growth in demand, nearly 350,000 would each year. This is 1.5 times as many as have been built since the early 2000s and would require more land than the area of the British Isles every year.
