This calculator can help you in better communicating a green power purchase to interested stakeholders by translating it from kilowatt-hours (kWh) purchased into more understandable terms, such as an equivalent number of passenger vehicles, homes, or coal plants.

The calculator uses EPA’s eGRID utility nonbaseload emissions rates and should not be used to determine the emissions associated with your conventional electricity use.

The calculator is provided by the US Environmental Protection Agency (EPA), and is accessed here.
