In winter there is less sun. Some politicians are now claiming that solar and wind currently generate less electricity than nuclear power. The data contradict.

The last German nuclear reactors are scheduled to go offline in mid-April. In its coalition agreement, the federal government relies on the power of renewable energies to reduce Germany’s CO2 emissions. But proponents of nuclear power are mobilizing against solar and wind energy. Sun and wind energy have so far contributed less to the power supply in December than the three remaining nuclear power plants, tweeted the FDP member of the Bundestag Frank Schäffler. That’s not true.

The fact is that the three remaining German nuclear power plants (AKW) contributed little to the net public electricity generation in Germany in 2022, in contrast to renewable energies such as wind and sun.

According to the Fraunhofer Institute for Solar Energy Systems, the share of nuclear power in the current year is around 6.7 percent (as of December 19, 11 a.m.). On the other hand, significantly more electricity for the public and private households comes from renewable energies. Wind (24.3 percent), sun (11 percent via grid feed-in) and other sustainable energy sources such as biomass together make up almost half of privately used electricity.

To date, 33.4 percent has been generated with lignite and hard coal. Natural gas accounts for 9.6 percent of electricity from the socket. Seen over the year, wind and sun are ahead in terms of electricity production compared to nuclear power plants. They generated around five times as much electricity for private households as the three nuclear reactors.

But what did it look like in the end? Is an alleged wind and sun doldrums actually noticeable in November and December? Here, too, current data from the Fraunhofer Institute paints a very different picture than critics of the energy transition would have us believe.

It is true for November that solar energy alone contributed around 4.2 percent less to public net electricity generation in Germany than nuclear energy (6.7 percent). The fact that the sun shines less often and less intensively is not untypical in the dark season. But the yield from wind turbines on land or at sea is far above the atomic value – a share of 29.7 percent.

In December, until Monday morning, December 19th, the values ​​for solar, wind and nuclear energy were indeed closer together than in the previous months. Nevertheless, wind (14.4 percent) and sun (1.2 percent) together have contributed more to the power supply this month than the last three German nuclear reactors (six percent).

The website “”, on which electricity consumption and production are visualized in real time, also shows that between November 17 and December 17, wind (around 12.9 percent) and sun (1.1 percent) were together larger share in electricity production than nuclear energy (5.8 percent).

Of course, there are also windless and cloudy winter days when households consume a lot of electricity, but hardly any solar or wind power is produced. As long as there is no corresponding capacity for electricity storage, fossil fuels such as coal or gas will continue to come into play.

However, it is wrong to say that the three nuclear reactors together surpass all solar and wind power plants in terms of electricity production. In addition, the power plants Isar 2, Neckarwestheim 2 and Emsland will only run in so-called stretching operation beyond the shutdown originally planned for the turn of the year. The reactor core continues to be used after the actual end of the cycle of the fuel elements. However, it gradually loses performance – around 0.5 percent a day, according to the Society for Plant and Reactor Safety.

After the end of a cycle, new fuel elements would actually have to be used. But because of the nuclear phase-out decided years ago, this step is ruled out for the German nuclear reactors according to the current legal situation.

The electricity price brake comes from March 1st – and is intended to relieve millions of households. FOCUS online uses examples to show how much money you can save with the electricity price brake and how you can benefit twice over from March 2023.
