Sales are growing so quickly that some installers wonder whether heat pumps could even wipe out the demand for new air conditioners in a few years and put a significant dent in the number of natural gas furnaces.

“Pay for more electricity” might not work very well, if everybody in a region uses resistive heat at the same time. I’m not sure what the solution is… maybe an overprovisioned power grid, cheaper battery tech, or tanks of renewable backup fuel like dimethyl ether?
Local power storage.
If you’re home had a battery bank, it could slow-charge pretty much all the time, then help pick up large on-demand loads like heating/cooling (air, water, food, etc).
Then the power grid would see a relatively steady load from each home with the batteries smoothing out spikes in usage.
Add on local generation like solar or wind to further reduce that load on the grid.
