Almost 52% of Germany's gross electricity consumption was produced by renewable electricity in 2023. An increase of 5% in one year. The goal is 80% by 2030; 100% by 2035. (www.cleanenergywire.org)

Yet again, renewables prove the naysayers wrong. This time last year people worried Germany couldn’t cope without Russian gas.

And this isn't entirly wrong. Germany is in one of the biggest economic crises into a livetime. Maybe even bigger than 2008 worldwide. And one big issue with this are the hight energy prizes.

Instead, efficiency measures and renewables mean Germany will never need Russian gas again.

Germany, like the United States for that matter, still imported gas! There are even claims that Germany in fact still imports Russian gas with a middleman.

The renewables have big yet unsolved issues with the problem of timing. Renewables produces energy if the wind blows and the sun shines, not when people actually demand energy.

I still see plenty of people arguing that 100% renewable powered grids are impossible - yet here it is happening, right in front of our eyes.

Seriously, I would not bet on the casestudy of Germany for that. I could be backfire horrific.

Can you explain this? Do transitional winds not cover mornings (the most energy heavy time of the day) rather well?

There are times in the year, which are called "Dunkelflaute" in German and in this time you have both: No solar energy and no wind energy. This mean, in this time you have a greater demand than produce.

Another problem is that the main demand of energy (privat households) is between 5 pm O'clock and 10 pm o'clock. At this time frame, you have usually lesser solar energy, while the peak of solar energy is during the noon, when the main part of people worked.

The problem is: How to store the energy for later use?
