What each device costs to run
Sorted by how much power they draw, which is not the same as how much they cost you — a heater pulls fifteen times what a television does and runs a fraction of the hours.

Annual figures use 18.44¢ per kWh (U.S. Energy Information Administration, 2026-05), and the basis column says how each one was reached. Devices certified in watts are run at the middle of their range for 4 hours a day. Devices with a compressor are not certified in watts at all — their yearly total is the measured figure, which already includes a defined pattern of use, so multiplying it by hours would count the usage twice. A dash in the standby column means the device has no standby mode rather than that we did not check.
