The greenest island in the world?

The smallest and most isolated of the Canary Islands, El Hierro, has a way of combining hydro and wind power that may allow it, one day, to get all its energy from renewable sources. In August it went for two hours without using its diesel power station at all - but this could be the start of a bigger green transformation.

At the end of June its new hydro-wind facility, Gorona del Viento, came fully on stream and in July and August it provided roughly half of the island's energy needs.
