Four new windfarms are to be built off the east coast.
The four windfarms will be at least three miles offshore
The go-ahead for the farms - two off Lincolnshire, one off Norfolk and the fourth off Essex - was announced by the government on Wednesday.
Each site is at least three miles offshore and will be made up of 30 turbines.
The new windfarms will produce more than 450 MW of electricity, enough to power a total of about 230,000 homes, equivalent to the population of a city more than four times the size of Norwich.
Energy Minister Stephen Timms, speaking at the Renewable Power Association Conference at Olympia, said wind power was playing a central role in the UK's renewable energy plans.
Sites of the new windfarms
Lincolnshire: Lynn, three miles off Skegness
Lincolnshire: Inner Dowsing, three miles north of Skegness
Norfolk: Cromer, about four miles off the coast
Essex: Gunfleet Sands, four miles off Clacton-on Sea
"We are building the first phase of offshore wind power and these new farms will help us towards our target of producing 10% of our electricity from renewable sources by 2010.
"We recently announced the next phase of wind farm development which could see windfarms powering up to one in six of UK households.
"Wind power technology is a clean and green alternative to fossil fuels."
He said the government was committed to reducing carbon dioxide emissions by 60% by 2050 and
renewable energy would help to reach that target.
'Clean, green electricity'
Of the 18 windfarm projects granted leases to use the seabed for construction, 12 have been given permission by the government to
Offshore Wind Power, which will build the Inner Dowsing windfarm, said construction would begin in 2004 and start generating power a year later.
The project will generate enough electricity for more than 60,000 homes, equivalent to the power needs of Skegness and surrounding areas.
"We believe that the windfarm will be an asset to Skegness and the
surrounding area, supplying homes with clean, green electricity and bringing local economic benefits," said project manager Jim Sandon.
