PHILIPS 273S1
The PHILIPS 273S1's certified consumption is 54 kWh per year, which prices out to about $9.86 at the national average rate — your hours of use scale that directly.

The same unit costs $7.05 a year in Nevada but $28 in Hawaii — electricity rates, not the appliance, make the difference.
