Annual Electricity Use

Where do I find this?  On your monthly electric bill your monthly energy use is listed. Add up the total number of KWh from your last 12 monthly invoices.

On average, electricity sources emit about 0.99 pounds of CO2 per kWh.

kWh/Yr
equals
total pounds of CO2 generated per year.
Annual Natural and Propane Gas Use 

Where do I find this? On your monthly gas bill your monthly gas use is listed. Add up the total number of gallons of propane gas and/or therms of natural gas usage from your last 12 monthly invoices.

On average, 1 therm of natural gas emit about 12.08 pounds of CO2.

On average, 1 gallon of propane emit about 12.65 pounds of CO2.
