Lord Adair Turner doesn’t do easy jobs. He ran the Financial Services Authority through the global crisis in 2008. He also ran the Pensions Commission, which had the small task of sorting out the UK savings problem, and the Confederation of British Industry — another organisation with a mammoth remit.

His latest gig is no less challenging. He now chairs the Energy Transitions Commission, which brings together power companies, investors, NGOs and more to try to limit global warming while somehow fostering economic development and social progress at the same time.
