Electric cars, anyone
Those rolling blackouts are the best possible exposure to the glaring hole in the "let's go electric" strategy for transport: the power networks won't be able to handle it.
It's OK if a small percentage of transport converts, but just do the numbers on just how much power you need if you make 25% of traffic electric: that's going to need some mighty fat cables to haul it around. The lucky ones can install a solar roof (credit to Elon Mush here, those solar roof tiles really are about the best), but inner city skyscraper dwellers don't have that luxury.
Yes, I'd love to see us all pollute a lot less and I have lived in places where you can rent electric which I really liked, but the reality is that we're not there yet.
