2017 is being reported as the 'greenest' summer on record by the National Grid. From 21 June to 22 September, almost 52 per cent of electricity generation came from low carbon sources ranging from renewables, such as solar and wind, to nuclear power, up from 35 per cent for the same period just four years ago.
24 per cent of power generation came just from renweables this summer, compared with 19.5 per cent last year.
The cost of renewable energy is falling and the cheaper prices for wind and solar is leading to new power deals across the world, despite investment in renewables falling.
Christiana Figueres, the former UN climate chief and now convenor of Mission 2020, said: “The economic case for renewables as the backbone of our global energy system is increasingly clear and proven. Offering ever greater bang-for-buck, renewables are quite simply the cheapest way to generate energy in an ever-growing number of countries.”
