Something I firmly believe is that there’s a ton of low hanging fruit for timing our energy use better. It is just hidden by the desire to present a uniform energy price.

Like why not run our water heaters when power is cheap? Then if that became a thing, we might even be interested in larger water heater tanks. Batteries cost per volume, you only pay for the surface are of a metal tank!

It's quite fun (and educational) with the kids to work out when to put the car on to charge, when to run the dryer etc, looking at the few days ahead forecasts.

Last month, we paid 11p per kWh on average, which is less than half what you'd pay on a standard tariff, and it's nice to be doing something good for the environment too. It's particularly satisfying to charge up the car when tariffs go negative.

The solar+battery revolution is doing for power what cell phones did for communications in the third world in the 90's and 2000's.
