I liked this bit from Gordon's interview in today's Times:
’Very quietly we have put solar panels on our home in Scotland quite some time ago. We have been operating with solar power for some time … The irony is my initial instinct was to have wind turbines. We are in a hill in an exposed area but I was persuaded by people who know about these things that even in that area — surrounded by massive winds & storms — solar power was a better way of generating electricity. It has been successful. Of all the different things that we deal with privately rather than ostentatiously, so as to get on with the business, you can make big changes & have an impact’.
