Sustainable energy — the growth of wind power in Sweden (part 5)


Sweden in 2014 produced about 64 TWh (42%) from large hydro and 62 TWh (41%) from nuclear. The rest came from wind 12 TWh (7.9%) and from other 13 TWh (8.5%), other being mostly biofuel and waste.

The interesting thing here is probably the change over time. In 2005 the distribution was 72 TWh (hydro), 70 TWh (nuclear), 0.9 TWh (wind), 12 TWh (other). With wind growing by 13x and the others staying relatively static, and energy use going down slightly. [1] There is quite a lot of variance per year, as the winter weather changes energy consumption quite significantly.

Electricity export has gone from about zero (2005-2007) to 15 TWh (2012-2014).

How can an individual contribute to this growth?

Possibly the most effective way to support the wind power growth in Sweden is to buy shares in a Swedish wind power cooperative. To show how this works I made a quick and dirty calculation: I bought 28 shares from OX2 windpower coop [2], which entitles me to 28,000 kWh at cost price. Which is what our house/home office uses per year. The price is about €700/share. But I bought shares from the market (people that want to sell their shares), which for some reason are cheaper. I paid about €590/share.

Over the last seven years (I haven’t had my shares that long), the saving on cost of electricity, which is tax free, would have been about €960/year. Which is about 5.7% ROI/year. Better than bank rates but worse than index linked stock market investments (I think).
