The "internetification" of the power grid is actually a wonderful way of putting it. The *whole initial idea* of the internet was to not have any single point of failure. The primal cold-war era fear that "one choke point got nuked, our computers should still be able to communicate". And so what do we see in Ukraine? The primary means of Russian winter terror is putting power plants and heating offline, which have triggered panic buying of batteries, inverters and, yes, solar panels.
But "everyone for themselves" is terrible for efficiency - not to speak about things like provisioning e.g. nuclear reactors that provide power regardless of weather is not exactly a neighborhood cooperative's project(yet*). "Everyone, together" beats everyone-for-themselves every time.

(*) molten salt / SMR (small modular reactors) might change that though not in the next years & disintegrating international law with "power plants are now open season" is not helping there...
