If you have a dynamic pricing contract of course you get a discount… If you don’t, you chose not to in favor of price stability 🤷
Though yeah, last time prices went negative in Germany I was still paying 10ct/kWh in just taxes and fees. Would be pretty cool if they’d have paid me for using electricity during that time, but of course that’s not how that works.
Edit—I forgot the most important bit: Obviously that doesn’t mean that we should invest less in renewables, but that we should invest in large-scale battery research like yesterday.
You… You think a battery is a magic physics defying substance?
I mean, I don’t see capitalism beeing a way to solve the climate crisis and do belive that degroth is going to happen (by design or desaster), but the success of renewable energy is very much a capitalism success story.
Clearly they only think bigger, better batteries are magic and physics defying. The batteries we have now are the best batteries that physics allows for, and they can’t be made more or bigger because… We already used up all the stuff for them. Yeah, that tracks.
“Battery” does not mean “chemical battery”. Gravity batteries, for example, already do provide power to midsized population centers around the world-- they’re called hydroelectric dams.
“gravity battery” BAHAHAHA. You don’t know shit about shit. How much power does a “gravity battery” store expressed in KWh/Volume. Given that number, how big would this “gravity battery” have to be to power a single city of ~1000000 for 1 day.
First off, don’t be rude. Second off, bold claim saying I don’t know shit about shit when you don’t know that a gravity battery is measured in mass (or volume, sure) and height, you know, that thing that gravity needs to make stuff move.
Anyways, I’m too lazy to calculate this myself, but the Hoover Dam website has better data than I do and probably smarter people doing the formulas anyways. It produces 4 billion kWh of power per year on average. The power usage of a city of 1,000,000 people varies based on average headcount of each household and especially by industrial (and commercial) consumption compared to residential consumption, but to take NYC as an example, it uses about 11 million kWh per day, and has a population of about 8 million, so it uses about 1.375 kWh per person per day. Over the course of a year, this means that a city of 1 million people would take 1.375*365*1,000,000 = 500 million kWh for a year. Conclusion: the Hoover Dam, which is a gravity battery, could fully power 8 cities of 1 million people, or almost exactly 1 New York City.
On top of that, it doesn’t have to power the city for a day, it only has to store unused energy produced during off-peak hours while the sun is shining and/or wind is blowing.
Right-- batteries don’t power cities, they just smooth out the power generation. The size of the battery is determined by the reliability of power generation, desired uptime, etc., not just by the power consumption of the city.
You linked the Wikipedia page on electric batteries. Of course it’s going to talk about the things you put in your remote, because Wikipedia is not a dictionary and that’s what most people mean when they say “battery”. See also, the pages on energy storage that refer to them as batteries:
You could also look at the Wikipedia disambiguation page for “battery”, found at /wiki/Battery, which mentions electrochemical batteries as the most common meaning and then has an entire section on energy storage that mentions “Energy storage, including batteries that are not electrochemical”.
Though it won’t show up as negative in the bill, not even a discount
Depends on where you live. With my tariff I get payed to use energy during negative price periods.
*paid
rope gets payed out.
money gets paid.
Fixed :)

Negative prices aren’t necessarily a good thing because they tend to curb investments. A Reddit comment explains it well: https://www.reddit.com/r/worldnews/comments/1didv4q/comment/l938q2a/

Yea if only magic physics defying substances existed. Surely capitalism would be able to solve our problems.

The classic capitalist solution “make it bigger, make more of it, there are absolutely zero limits.”
Quick question, how big would a battery have to be to power a single city of >1000000 for a single day, show your work.

It’s actually not anything new. It’s called Pumped Storage Hydropower .

Sorry, but you are wrong, battery means exactly chemical battery
Gravity electrical storage is not a battery
