CAMPAIGNERS have called on the UK Government to rethink plans to curb the roll-out of onshore wind power.

The demand from the World Wildlife Fund comes as newly published figures reveal that last month broke all previous records for wind power output in Scotland in May.

Analysis by WWF Scotland of wind and solar data provided by WeatherEnergy found that for the month of May wind power in Scotland alone provided enough electricity to the National Grid to supply just less than half the electrical needs of all Scottish households.

WWF Scotland's director Lang Banks said: "Strong winds throughout the month helped to make it a record-breaking May for wind power output, with enough clean energy generated to supply the needs of 47% of Scotland's entire electricity demand from homes, businesses and industry for the month.

"However, despite the fact onshore wind power is clearly working, the continued development of this clean energy technology in Scotland is at risk as a result of UK plans to end support for the industry earlier than planned.

"Cutting support now for the lowest cost renewable technology would be a backwards step that will either see consumer bills rise or our climate targets missed."

Scotland's energy minister Fergus Ewing has called on the UK to clarify the Government's plans for reforming the subsidy regime for the sector.

The Department of Energy and Climate Change (DECC) is expected to announce measures to deliver on the Conservatives' manifesto pledge to ''end any new public subsidy'' for onshore wind farms.

Mr Ewing said that such a move would set a "terrible example."

A DECC spokesman said: "We will consult the devolved administrations on the government's commitment to end new public subsidy for onshore wind projects."
