The way the Washington Post ran a similar article a week ago.
Utilities could (and should) have started planning for this years ago, as increased electric use was pretty much inevitable as one of the key parts of decarbonization is to electrify everything.
I remember reading a study from Japan a few years ago. It related the country’s percent GDP investment in renewables vs power consumption of the population over time. The conclusion was, that the more GDP they invested in renewable power generation, the more overall power was available, which the population consumed.
Old power sources didn’t go away. There is just another source available. It’s an addictive effect, not a replacement of power sources.
I tried searching for the article again a few months later, but I couldn’t find it… I wouldn’t be surprised if it was removed or hidden, considering it is objective evidence against being able to buy our way of this problem.
