Yep. Here in Colorado I installed two powerwalls moderately subsidized by the electricity company. It’s not going to save me meaningful amounts of money even in the long term and I would much rather see energy issues solved at a societal level. But our electricity provider is just unable to reliably keep the lights on through winter and wildfire season, I.e. most of the year. Since installing the batteries a couple years ago our home has stayed warm and lit through two multi-day outages when neighbors have had to go stay in a hotel.

This isn't a federal government issue in the US. Local and state governments dropped the ball here. No one wants to pay what it costs to bury power lines in most locales, and we have a ton of byzantine regulations that make it slow and expensive to add generation capacity.

What are you going to do when winds rip the solar panels off your roof, or drop a big tree branch on them? Who will you call to repair it? Who will pay for it? How many days will it take? Have fun.
