Mildly Interesting

This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.

This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?

Just post some stuff and don't spam.

It's still not earning you money to spend electricity because you still have to pay the transfer fee which is around 6 cents / kWh but it's pretty damn cheap nevertheless, mostly because of the excess in wind energy.

Last winter because of a mistake it dropped down to negative 50 cents / kWh for few hours, averaging negative 20 cents for the entire day. People were literally earning money by spending electricity. Some were running electric heaters outside in the middle of the winter.

Or water batteries for dams if your neighbors don't need your surplus, this way you don't need to extract lithium to produce regular batteries to store the surplus

Lithium isn't going to be the way to store electricity on the grid. I wish people would stop bringing it up.

There isn't going to be a single thing. Pumped hydro, flywheels, sodium-ion, flow batteries, and heating up sand all have a place.
