the energy mix of electric grids everywhere is changing rapidly to include more renewable technologies, and especially so on islands.
puerto rico's grid was in quite bad shape, but it was also originally designed around importing most of its fuel and operating a single (or few) large generator supplying the island. this setup created concentrated points of failure in the event of a natural disaster and also now makes little economic sense given recent advancements in PV and battery technology.
Oh come on. Every developed nation concentrates their power generation. They don't all run into the same kinds of issues that Puerto Rico did after a natural disaster. What Puerto Rico went through was institutional failure.
OTOH most developed nations do not have such a high risk of natural disasters. Tropical countries and regions live with that constantly and it's getting worse with climate change.
