A woman plays the bagpipe on the pier on the island of Eigg, Inner Hebrides, Scotland, May 25, 2014. The Scottish island of Eigg has the first completely wind, water and sun-powered electricity grid in the world, according to the Isle of Eigg Heritage Trust. According to a local, between 85 and 95 percent of the energy consumed on the island comes from renewable resources.
Scottish nationalists say that the best way to harness Scotland's renewable energy potential is to vote for independence on Sept 18, although an independent Scotland would also benefit from large oil reserves in the North Sea. Campaigners to keep Scotland in the United Kingdom argue that the growing renewables sector would suffer with independence, as the cost of new infrastructure would not be spread out across the whole of Britain.
