The Government’s bet on subsidising renewable energy power has already halved the carbon emissions from the power generation industry over the past five years.

Fresh data from National Grid has revealed that tumbling clean energy records in the past year, including the “greenest summer ever” after low-carbon sources made up more than 52pc of the energy mix. The boom in solar panels and wind turbines also led to the first full 24 hour day without coal-power since the Industrial Revolution.

Solar power reached a fresh record by making up a quarter of Britain’s electricity supply on Friday May 26 at 8.9GW, while wind turbines set a new record on Dec 7. Overall, renewable energy reached its highest total output level at 19.2GW in late March.

Duncan Burt, the head of National Grid’s system operations said the record-breaking year marked “a new era” in grid operations.

“We now have significant volumes of renewable energy on the system which poses an exciting challenge for us in ensuring the supply and demand is matched second by second,” he said. “As this trend continues, our ability to forecast these patterns is becoming more and more important,” he added.
