Energy Storage is a large problem- the German Experience 13/12/20

Energy storage is a worse problem in Germany because they have longer cold periods with less sun than Australia. It seems that pumped hydro storage is our best option, but this article is correct that it requires a lot of energy alternatives for when the wind does not blow and the sun does not shine.

Demand management is also important, which means shifting things like off peak hot water to when the sun shines, but also paying people to switch off. If there is only a peak demand for a few hours a year, it is cheaper to pay people to turn off than to have a power source that is only used a few hours a year.

But articles about the problems in the German grid have been around for a long time and lessons need to be learned.

Those of us who want to move to renewable energy need to be aware of the problems and to address them, or we just look like naive ideologues.
