$101.05 a year A typical ENERGY STAR certified dehumidifier uses 343 kWh a year. At Rhode Island's average residential price of 29.46¢ per kWh, that is $101.05 a year, or $8.42 a month.
The tariff scales the whole rail; the model you buy is what moves the gate along it. The most efficient certified dehumidifier on this tariff draws $30.93 a year, the least efficient $827.24 — a standing difference of $796.30 a year for an appliance doing the same job.
How this is worked out
- Take the certified annual consumption for the appliance class off the EPA's ENERGY STAR register — the median of every listed model, not a wattage anyone assumed.
- Take the residential tariff off the EIA's Electric Power Monthly, table 5.6.A. Here that is Rhode Island's residential average, 29.46¢ per kWh.
- Multiply, then divide by 100 to come out of cents. Nothing is rounded before this line.
- Derive the rest of the schedule from that one figure: ÷ 12 monthly, ÷ 365 daily, × 10 for a ten-year life.
- Overwrite the tariff terminal with the rate printed on your own bill and the register re-reads. The certified consumption does not move — that is the half of the sum nobody gets to opinion their way out of.
