This makes me think about Taleb's fragile vs robust vs antifragile systems with relation to the power grid. Is a nation-sized power grid even a good idea anymore? If most places were powered by a local cooperative solar + wind + storage system, it would be less efficient, but wouldn't it also be a lot more robust against a CME, and also everything else? Individual systems would go down all the time, but overall the system as a whole would never be able to be taken down by pretty much anything.
