To be fair: Wind energy and solar has gained a lot of traction in Germany and is producing more and more energy every year.

Sadly "the big four" (energy companies) are influencing politics and are actively halting progress on renewables which leads to really strange effects.

My landlord installed a rather big solar system on the roof and due to its size, the energy company can decide to remotely shut it off when there's enough energy in the grid.

It's really a shame and a lot of corruption is going on there.

Also: Little to no research on energy storage was done in the last 25 years, because of all this corruption.
