Mr Miliband opened the biggest onshore wind farm in the south of England at Romney Marsh in Kent yesterday.

The Climate Change Secretary said Britain needs wind farms like the 26 turbine Little Cheney Court wind energy project to diversify its energy sources in order to be less dependent on imported gas.

Kevin McCullough, chief operating officer at RWE Innogy - the operator of the Little Cheney Court Wind Farm said: “This is a landmark renewable energy project for the South East of England and shows the region is playing an important part in the global battle against climate change…

Little Cheyne Court will prevent the release of thousands of tonnes of carbon dioxide every year while also contributing to the UK’s energy security. A great deal of hard work has gone into this project since we first announced our plans to build a wind farm here in 2002 and I am delighted Little Cheyne Court is now generating electricity.”

The wind energy project is expected to generate enough clean electricity to meet the average annual needs of around 33,300 homes - equivalent to about three quarters of the homes in the Shepway district council area.

Ahead of the launch of a new Renewable Energy Strategy expected tomorrow, Miliband said that reforms of the planning system were needed in the UK along with greater efforts to persuade people of the benefits of greener technologies such as onshore wind energy.

Meanwhile in the UK, 50 organisations have formed a coalition led by the Town and Country Planning Association (TCPA) and Friends of the Earth to lobby the Department for Communities and Local Government for an updated climate change policy. The coalition believe onshore wind energy needs to be seriously considered in the fight against climate change.
