>Really impressive. It must have been June or July that there was a major power cut that affected most major cities in Bolivia. Then the power cut in the United States. I think a few days ago there was another one somewhere in Europe (?), and now in Italy. I wonder whether there are other power cuts which I overlooked.

Simply, and generally due to a lack of investment in infrastructure. That was the underlying reason for the one in Bolivia, USA/Canada and Uk recently. I don't know about Italy but I'd suspect the same.

At least in our country, it was known for years that the infrastructure needs fixing. Fixing costs money. Lots of money. Ask the politicians.
