Greg Jackson strikes a rueful smile. “There is evidence they are listening,” he says of the government. “But there is a lot more low-hanging fruit they could be picking.”
Jackson is the founder and chief executive of Octopus Energy, Britain’s biggest electricity and gas supplier. He is a supporter of green energy and a member of the Cabinet Office Board. “The Iran crisis has shone a light on our energy needs,” he says. “The UK must not be so vulnerable when something like this occurs.”
