For me personally, adding stickers is much more important than chat backups - at least on a day-to-day basis. The last time I switched devices was 3.5 years ago, the last time I used a sticker was 3.5 hours ago.

I was looking at commercial induction woks earlier - they use on the order of 15kW per wok, so about 51,000 BTU burner - but all the heat goes into the pan instead of the hood, so more equivalent to a 150k BTU gas burner

A small fraction of the cost of electricity is fuel cost. A much larger fraction is staffing, maintenance, and capital costs amortization. Distribution and maintenance fees are largely covered by per kWh price. The turbine I mentioned to do

Even burning natural gas in a peaker plant to generate electricity (nTh ≈ 0.6), and account for transmission losses(~0.9), and then using that electricity to run a heat pump (~2.5) - is still more efficient than natgas space heating

On a per-unit basis, obviously the commercial users. But on a per-building and city-wide basis, almost definitely residential - huge amount of natural gas is used for residential space heating.
