A record amount of clean electricity was generated by wind power in 2014, according to National Grid’s official statistics.

In 2014, wind had generated enough electricity meeting the needs of more than 6.7 million UK households, marking a 15% increase on the amount generated in 2013 (up from 24.5 terawatt hours to 28.1 TWh in 2014).

Additionally, 9.3% of the UK’s total electricity supply in 2014, up from 7.8% in 2013, was provided by wind farms which were feeding into the grid as well as by single turbines connected to local networks.

RenewableUK deputy chief executive Maf Smith said: "It’s great to start 2015 with some good news about the massive quantities of clean electricity we’re now generating from wind, with new records being set month after month, quarter after quarter, and year on year, as we increase our capacity to harness one of Britain’s best natural resources.

In December, wind accounted for 14% of all UK electricity generated, breaking previous record of 13% in December 2013.

Smith said: "The cost of energy has become an important political issue, so now would be a good time for voters, prospective parliamentary candidates and MPs to take account of the fact that onshore wind is the cheapest form of renewable energy we have at our fingertips.

"So if we’re serious about cutting bills, and securing an indigenous supply of clean power, all parties need to support it in the months ahead."
