The miracle of Swedish wind: it generates more electricity than nuclear with half the installed power

On Monday, the 5.5 GW of wind power installed in Sweden contributed more energy to the Scandinavian country's grid than the 9.5 GW of its nuclear power plants, a renewable energy achievement that followed a tweet from the executive secretary of the United Nations Framework Convention on Climate Change (UNFCCC), Christiana Figueres.

As the table shared by Figueres shows, hydropower (vattenkraft) was the largest energy supplier for Sweden on June 1, followed by wind (Vindkraft), nuclear (kärnkraft), and small amounts of biomass (varmekraft) and unspecified fossil fuels (ospecificerat).

To put these data into context, Sweden - which has one of the world's highest individual levels of energy consumption - generated 152.5 TWh in 2013, of which 65.8 TWh (43%) were nuclear and 61.3 TWh (40%). ) of hydroelectric plants. Wind power provided only 10 TWh and various fossil fuels 5 TWh and biofuels and waste 10.6 TWh. Apparently, by law, the network operator Svenska Kraftnatt it must ensure that there is 2,000 MWe of reserve capacity in winter.

According to World Nuclear Association, Sweden currently has 10 operating nuclear reactors (9,487 MWe) that typically provide around 40% of its electricity needs. The country's total wind capacity at the end of 2014 was 5,425 MW distributed among 840 wind farms, which represent between 15% and 20% of the country's electricity mix.

Nuclear power has had an interesting journey in Sweden, where its Parliament voted in favor of its elimination back in 1980, and then this policy was repealed in June 2010, after which 1,600 MWe of new capacity were added in upgrades of the existing reactors.

Sweden's wind energy profile, by contrast, has been on a fairly steep and steady upward trajectory in recent years, driven by the common renewables support scheme it launched with Norway in 2012 - the first of its kind. in the world, okay Reuters - to increase production from renewable energy sources to 26.4 terawatt hours (TWh) in 2020.

According to the wind energy data of the International Energy Agency (IEA), and as can be seen reflected in the previous table, during the last five years the Total installed wind power in Sweden has soared from 1,560 MW at the end of 2009, to 4,459 MW distributed among 2,681 wind turbines at the end of 2013, to finish 2014 with a total of 5,425 MW.
