What Air Emissions Are Caused by the Electricity I Use?

To find your emissions, you can choose one of the three options:

• Option 1: You can collect a year's worth of utility bills and enter information about your utility use, measured in kilowatt hours (kWh), for each month of the year. (This option provides the most precise answer.)

• Option 2: You can estimate your average monthly utility use for the year.

• Option 3: You can use the default values provided for average residential or commercial utility use.

For the most precise answer, collect a year's worth of utility bills and enter the kWh shown on each month's bill below.

Estimate your average monthly utility use in kWh, and enter this information in the box at the right.
