Negative electricity prices occurred in Switzerland for a few hours the other day - just a few months after electricity prices reached absolute record highs. Private consumers in Switzerland, however, do not benefit directly from the novel phenomenon.
On windy and sunny Sundays, when wind turbines and photovoltaic systems produce a lot of electricity but little is needed, European electricity prices, and thus also Swiss prices, temporarily fall into the red.
You’ve got the wrong impression that I said that in defense of concrete towers. I wouldn’t like having that in the backyard either and they seem terribly inefficient.
A water tower is a good idea! I mean if people accept those huge grain silos in cities, one filled with water would also work. That way we could have storage closer to consumers and protect landscapes.
