In Scotland, the renewable sources produced 32% more power than any other source, during the first six months of 2014.
A total of 10.3 terawatt-hours (TWh) of power has been generated by the renewable sector, compared to 7.8TWh2 from nuclear power generation, which was the region’s primary source of electricity earlier.
Further, the coal and gas-fired plants have produced a total of 5.6TWh and 1.4TWh respectively during the first half of 2014.
Scottish Renewables chief executive Niall Stuart said: "The announcement that renewables have become Scotland’s main source of electricity is historic news for our country, and shows the investment made in the sector is helping to deliver more power than ever before to our homes and businesses.
"This important milestone is good news for anyone who cares about Scotland’s economy, our energy security and our efforts to tackle climate change.
"Every unit of power generated from renewables means less carbon emitted from the burning of fossil fuels, decreases our reliance on imported energy and supports jobs and investment in communities across Scotland."
