Wasted wind power will add £40 to the average UK household's electricity bill in 2023, according to a think tank. That figure could increase to £150 in 2026, Carbon Tracker has estimated.
When it is very windy, the grid cannot handle the extra power generated. Wind farms are paid to switch off and gas-powered stations are paid to fire up. The cost is passed on to consumers.
Most of the UK's offshore wind farms are in England -
Dogger Bank off the coast of Yorkshire is the largest in the world. Meanwhile, around half of onshore wind farms are in Scotland but most electricity is used in south-east England.
Carbon Tracker said the main problem in getting electricity to where it is needed is a bottleneck in transmission between Scotland and England.
