Many people are aware that Iceland has the cleanest energy in the world by far. The island-nation generates 100% of its electricity from renewables such as hydroelectric and geothermal sources, and it’s also flirting with wind power. What those same people might not realize, however, is that this results in some of the cheapest electricity in the world.

Switching electricity supplier could shave pounds off your bills. But it’s not always about how much hard cash you could save. You might be fed up with poor customer service, you might want greater visibility of your usage through an app or you might want to choose your supplier based on their green credentials, or whether they supply a smart meter.
