When we arrived in Antarctica and approached Scott Base for the first time, I was surprised to notice 3 large wind turbines above the base on Crater Hill. I’d never seen them in any photos of the area and had read that the electricity for the base came from diesel generators, which it had, until last December. Now the generators are silent and the base is run entirely on wind power, with the surplus electricity going to McMurdo Station ( the American Antarctic base located 3km away).

The wind turbines themselves are specially designed for low temperature operation, and so they do not have gearboxes with oil that can ice up. Erecting them was an engineering feat in itself and the foundations had to be made in New Zealand and transported here by ship due to the difficulty of setting concrete in extreme low temperatures.

Scott Base has always prided itself on being as green on the inside as it is on the outside, and this is a very significant step towards sustainability. It’s a great feeling to realise that every time you switch on a light or log on to a computer, the juice is provided by the wind whistling around outside!
