We bought grid tied solar for our farm ten years ago but when power went out so did the solar so we added powerwalls five years ago. We have a small pig farm that sells to restaurants and direct to the public. The batteries are there to save my freezers if power goes out . Both the solar and the batteries have preformed flawlessly. With current electric rates the system has paid back its purchase price in energy produced to date. There is thousands of dollars of frozen product the system protects. The solar panels still have over a decade of life in them and hopefully the batteries last for another five years at least. With current electric rates that system would generate an additional $24,000 of energy. So system over its lifetime should produce double the unsubsidized purchase price.

I also bought an electric tractor which is trouble prone rather than trouble free, so being a first adapter isn’t always a smart move… but it is kinda fun.

No bunker here but maintaining a farm is some sort of resilience … if food calories count.

"This got me wondering: Who else is shoring up renewable power out of security—not climate—concerns?"

National security /defence departments the world over - well, among the richest and most militarized countries - must have gone down this same road on both the micro and macro scales. At one end of the spectrum, there are the national plans for reserves of essential materials, products etc, so that economies have a certain resilience to supply chain problems, price fluctuations. These things are often public. But there must also be unpublished reports and plans, and actual infrastructure and physical preparations in some cases, so that national societies and economies, and especially their key assets, power centres, etc, are not weakened relative to their enemies or rivals. Just as we know, for example, about how the US military has since the 1950s had an entire infrastructure set up so that it could continue to operate after an all-out nuclear attack, they must have adapted that over the years according to their changing perception of the threats and risks, and the technologies available to guard against them. I would bet that deep in the military archives there are some pretty interesting documents relative to our ecological predicament and measures to combat the different threats to power it may bring.
