Electricity and Natural Gas have a “Carbon Value”. Carbon is created when either are used. Natural Gas is a carbon based fuel that releases carbon into the air when burned. Electricity has a Carbon Value due to the way it is generated. Electricity is generated by hydro, solar and wind but it is also created by burning Natural Gas and Coal. Approximately 25% of the electricity consumed in California is from a carbon emitting generation plant.
The total amount of carbon you create is called your Carbon Footprint. By using efficient co-generation to satisfy two of your energy needs from one fuel source you are reduce your Carbon Footprint. It is not unusual to see the Carbon Footprint of a facility reduced by as much as 10% while saving money at the same time!
