Why EcoGuide?
Every figure on this site is built from your state's current regulated reference tariff, which means the answer you get is the one your bill will roughly agree with. Plenty of calculator sites quietly run on a national average from years ago, so their "45 cents an hour" might be your 60. Ours tells you the rate it used, where that rate came from, and refreshes all eight states every July when the new rates land.
The calculators lean on the registry data the whole way down, so you can look up your actual fridge rather than a guess. Your location and your My Home tally live in your browser and nowhere else, which means no account, no emails from us, and nothing to unsubscribe from later. Get the number, pocket the tricks that cut it, and get back to your day.
