Technology Connections has an interesting video about pre-cooling:

The author also made a good point that despite wind and solar being intermittent, they are actually fairly predictable a or less day in advance (thanks to weather forecasts).



The video is super articulate.

I like what he did at 6:49:

> So that I can take advantage of these low rates at night, I use a roughly 16kWh battery that I just happen to have lying around. I charge it up over night starting at 10pm on the dot, and it's done charging usually by 3 or 4 in the morning. I keep it topped off until around 7, and then I start using it during the day. And it doesn't need to be charged again until the evening. Now the reason I just happen to have that battery lying around, is because that battery... is my house.


You can see this play out in Texas, at the ERCOT dashboard.

Interestingly, you can see that wind and solar are anticorrelated there: wind tends to die down during the day, and spring back up at night.
