>Australia has so much electricity during the day they’re talking about making I free for everyone in the middle of the day.

Not just talking about it, if you get a smart meter and sign up for a plan that matches the grid rates you can actually be paid to take electricity during the day right now.

If you're wondering "couldn't you just make bank with a battery" yes you can. In fact Australia dominates the world in grid connected storage (per capita) and this chart itself is actually out of date (it's growing even faster than shown).

I'll also point out that gas and oil generation has declined rapidly.

For anyone that thinks renewables can't phase out peaker plants it happens very naturally and rapidly once there's enough solar to set rates negative in the day.
