The same deal happened when offices started using personal computers. A complete desktop computer system used 400 to 1500 watts around 1995. Office circuit breakers kept tripping, electrical closets overheated, and there was not nearly enough air conditioning to pump all that heat out. Local grids overloaded and there were regular blackouts. Power companies panicked at the idea of every home consuming another 1KW for a computer. (And this gave Enron a really bad idea for profit)
People bought backup power supplies and the wires got upgraded. Desktop were made more power efficient. Happy ending.
