I have batteries in my home - 4.8kWh worth. The technology is very real.

But, also, we have to plan for tomorrow. We can predict with some degree of certainty how technology will develop. Tomorrow's computers are likely to be faster than today's; so we'll build a broadband network which is capable of exceeding today's demand.

It's the same with electricity. Nuclear has had decades to prove itself and come up short every single time. Solar and wind are exceeding expectations. Battery technology is rapidly evolving. Should we base our decisions on today's technology or tomorrow's?

Given how cheap 20kWh of battery is compared with the total cost of a house it’s shocking that there aren’t building requirements mandating that much storage.
