They have been the cause of many debates throughout the years and now the Conservatives have said they will not subsidise any more new onshore wind farms if they win the 2015 general election.

It comes following the announcement by energy minister, Michael Fallon, who said any project not granted planning permission before the election would not get funds.

He said it was because the UK would already have enough wind power to meet 2020 EU targets. The government claim there is currently enough wind power to provide energy to four million homes, forecast to rise to seven million by 2020.

The plans would also include a change in the law so that within six month the onus would be on councils in England and Wales to give the 'decisive say' on new onshore wind farms from 2015. Applications would then be handled by local planning authorities.

The Lib Dems said they had blocked such changes being made by the coalition.
