Sky’s offices, retail stores and journalism hubs across the world are now powered solely by clean power, with the media giant today announcing it has reached its 100 per cent renewable electricity target. Sky, which has a target to become a net zero business by 2030, said delivering on the renewable power goal for 2020 had cut its Scope 1 and 2 greenhoues gas emissions by 22.7 per cent from its 2018 baseline under its Science-Based Targets initiative- approved climate strategy.

Why extreme weather is putting renewable systems in the spotlight. Aiming for 100% renewable energy systems is the Holy Grail, but in the shorter term we might have to accept that some form of fossil fuel back-up remains necessary for periods of extreme weather. At one end of the scale is what the Germans call the kalte Dunkelflaute, when it is cold, dark and cloudy with virtually no wind. The UK, where renewables provide nearly a third of all power, half of this generated by wind energy, suffered a similar situation this month, except it was very hot. In both cases, reliance on high amounts of wind energy can become problematic. “Those working on power system decarbonisation are well aware of this issue, although fossil fuel industry representatives often make it look as if they don’t understand what is happening,” says Jan Rosenow from the Regulatory Assistance Project, a non-profit aimed at enabling the energy transition. “It is a challenge, but one that can be addressed.” Building out huge amounts of batteries, where energy can be stored, is often touted as important to solving this issue, but batteries are, at best, only part of the solution.
