PHILIPS 222B9
The PHILIPS 222B9's certified consumption is 50 kWh per year, which prices out to about $9.15 at the national average rate — your hours of use scale that directly.

The same unit costs $6.54 a year in Nevada but $26 in Hawaii — electricity rates, not the appliance, make the difference.
