because you mainly need power when the sun isn't shining. Once you add in costs of electricity storage it's not economical.

- pjc50 10y agoNot really, you mainly need it during the day for commercial demand. At the moment we're still in the phase of "negative demand" in almost all countries, where there's no question of storage and it just manifests as the ability to turn fossil power stations off. The UK has at the moment turned off most of its coal generation capacity for the summer. (Is there a US equivalent of http://www.gridwatch.templar.co.uk/ http://www.gridwatch.templar.co.uk/ ?)
- imtringued 10y agoHere is a live graph of power production/consumption in germany. You should take the prediction for the rest of the day with a grain of salt though. https://www.agora-energiewende.de/en/topics/-agothem-/Produkt/produkt/76/Agorameter/ https://www.agora-energiewende.de/en/topics/-agothem-/Produk...
- daurnimator 10y agoWhat you'll notice is that Lignite (=Brown Coal)+Nuclear+Biomass+Water (i.e. the base generation) are sitting at the lowest point of consumption for the day. Solar will only be able to increase (without storage) until there is no black coal used.
- kuschku 10y agoCorrect, but Wind is already taking over large parts of the lignite part. And the pumped water is storage for solar, btw. For us as a society, it doesn’t matter if we end up with 100% solar, but only that we end up with 100% combined of Biomass, Pumped Hydro, Wind, Solar, Water.
