The world's biggest wind developer has warned of a profits slump because the British summer was too warm and calm this year.
Danish firm Orsted, which has 12 wind farms in Britain which generate 7 per cent of the country's electricity, became the latest to bemoan slowing speeds amid worries over the UK's energy strategy.
The company said it now expects annual profits this year between £2.8 billion and £3.1 billion, compared to previous hopes of between £2.9 billion and £3.25 billion.
It said the 'primary driver' for this was 'the impact from the lower-than-normal offshore wind speeds' across its sites, which include Hornsea 2, the world's largest offshore wind farm, off the Yorkshire coast.
It is the latest cause for concern over the country's energy strategy after Ed Miliband's Net Zero ambitions were last week blamed for a shock rise in energy bills that will see millions pay more this winter.
