In a novel use of clean energy, the world’s most northerly town will soon be the first to get electricity from a sub-sea power station run on tidal currents tugged by the moon.

Gigantic forces in the oceans — waves, currents and tides — have often proved too costly or awkward to harness, compared to wind or solar power in global efforts to cut reliance on nuclear power or on fossil fuels blamed for global warming.

From late November or early December, however, a tidal current will start turning the blades of a windmill-like turbine standing on the seabed near Kvalsund at the Arctic tip of Norway.
