Much of Cuba, particularly the western part and the far southeast, have had nearly no power for all of the last 4 to 5 weeks. Those are not "outages" when they last 3, 4, 5 days or more at a time... and come back only to fail again.
For how many total minutes? In Cuba, it is measured in whole days and weeks.
I was in a number of hurricanes, the last one had my home with no electricity for 8 total days. At the stations, we were on generators for 5 days at the studios and for about two weeks at the transmitter.
Many of the power "failures" in California are not failures at all: they are caused by the imposed liability put on power companies if winds cause wires to spark and cause forest fires. To avoid that, the power companies have no alternative but to simply shut off power every time there are high winds. This is what you get when you have people who, at best, went to law school legislating about technology. Same results as giving a loaded machine gun to a chimpanzee.
