It’s hard to spend any time in Sheffield without running into the legacy of Alderman John George Graves. At the central library there’s the Graves Art Gallery. Ecclesall Woods, the ancient woodland on the west side of town, was donated to the city by Alderman Graves. Even Sheffield University’s student union owes its existence to a Graves donation.
Stand in Coronation Park, high above the north Cornish town of Wadebridge, and you can look down on the future of localised energy supply. Solar panels glint from the roofs of homes and schools, wind turbines whirr and solar farms are just visible in the distance. The town now gets 3% of its energy supply from renewables, and plans to have reached 100% by 2020.
