Renewable energy firms warn of difficult conditions amid slow winds

Lower-than-normal wind speeds and supply chain problems pile pressure on Orsted and Vestas

Two of the world's biggest wind energy companies have warned of difficult conditions as slower-than-usual winds and supply chain difficulties delay manufacturing.

Orsted, a Danish company, said lower-than-normal wind speeds throughout the third quarter had affected its earnings. Across the first nine months of 2021 slow winds cost the company 2.5bn Danish kroner (290m) compared with the previous year. Orsted makes about two-thirds of its revenues from offshore wind including off the UK's coasts.
