The greenest island

An Sgurr on Scotland’s Isle of Eigg is one of the most striking landforms you’ll ever clap eyes on: a mile-long, cliff-sided pitchstone wedge. And it’s a great spot to admire Britain’s greenest island: since 2008 a blend of wind, water and solar power has kept Eigg energy-sufficient (and you can’t bring a car either).
