What's Your Watt

The Watt’s Your Watt program provides resources to help San Francisco residents reduce their electrical consumption.

Why Participate

Reducing your electrical use is great for your pocket and the environment. One of the best ways to reduce your electricity use is to figure out how much wattage each of your electrical devices draws and how many hours they are in operation in a year. Watt meters show you how much energy your household appliances consume, their operating costs and environmental impact. Once you know how much each device uses, you can tackle each one in turn.

The What's Your Watt program allows San Francisco residents to check out watt meters from their local San Francisco branch library and keep them for three weeks. Instructions are provided in multiple languages.

Meter settings

Your meter should be set for local San Francisco rates and carbon equivalents of $0.137 per kWh, and .551 lbs of CO2 per /kWh. For a more tailored configuration, check your utility bill for your exact rate.
