So what they are saying is that our current financial system is too focused on short term gains to cope with short term losses?

Sigh, when I grew up, I was allways taught to save money so that I have a buffer to fall back on. This concept seems to have completely gone out the window for busniesses lately.

I dislike the talk about how capitalism is bad as a general concept, but when seeing stuff like this I do agree with it in parts.

Ok, so let's solve the issue.

There is too much electricity, so generating power to transmit to the network will cost us money.

This has an easy solution, just don't transmit it to the network.

Build a battery facility where you store the power instead, infact if the price of electricity is negative, use the power on the grid and charge your batteries as well, I mean, when the electricity cost is negative, you are being paid to consume power.

Then when the sun goes down, and the electricity price goes up, you sell the charge you have in the batteries.

Depending on your location you could even set up a pumped storage system, where instead of batteries getting charged, you use the cheap excess energy to pump a resarvoir full of water, and release it when you need the power.

This is exactly what we're gonna see on a large scale in a few years.

I’m very hopeful for flow batteries to improve to a point where they can be very cheaply installed at scale. Seems much better environmentally than lithium ion, and the drawbacks matter less for grid storage.

Flow battery drawbacks aren't drawbacks for home use, let alone grid scale.

Too heavy, and too big. This is compared to an automotive battery though. They take up the size of something like a fridge. They are also expensive but prices are bound to come down once production is up. But they have claimed zero capacity degradation for decades they say. And the liquid inside is a fire retardant, so if you puncture a battery that would actually put out the fire.

There are number of videos on YouTube, it's an interesting technology.

Absolutely. Home use is what got me interested in them in the first place. I love to DIY stuff (recently I’ve been building planar speakers from scratch) and had the crazy idea of building one for my house.
