WattZ Electricity Bill Estimator

WattZ helps you quickly estimate the electricity usage of virtually any house in the US, helping prospective renters or homeowners eliminate big surprise bills.

Users can see a quick estimation of the electricity usage in their neighborhood (or any city), with color coded pins on a map (green for low electricity bills, yellow for medium, or red for high), or they can search for the electricity usage of a specific address.

Behind the scenes we are checking the house specs at Zillow, generating a usage estimate using the Department of Energy’s Building Performance Database, and estimating a total cost using the DoE’s EIA API for average electricity prices. (No endorsement is implied for WattZ from Zillow or the Department of Energy.)
