Yesterday the power company had curtailable customers cut power usage by 2.5%, and expect that later this week they'll have to go to the next level, 5%.
The step after that is 'rotating feeder and substation blackouts'. They don't think that'll happen.
Anyway, I turned off my fan. It's possible the air conditioner is downstairs, so I may go sit in that room and read.
(My laptop suddenly turned off earlier this week. I suspect it was overheated. I turned it back on immediately, though We've been getting over 100f, and over 110 with the heat index.)
