Electricity reduction ideas
Electricity is measured in kiloWatthours (kWhs). Using electricity doesn't generate any CO2...but creating the electricity in the first place may--it depends on how the electricity was generated. If your electricity is coming from a hydroelectric dam or a photovoltaic solar panel or a windmill, you aren't generating CO2. If your electricity is coming from a coal fired or natural gas burning power plant, you are generating CO2.
To calculate your CO2 footprint from electricity consumption, EcoShift uses your state average footprint for electricity. You can see the source numbers here:
