Have you ever wondered what your carbon footprint is? I found this great carbon footprint calculator on PG&E's website.
Based on PG&E's calculation assumptions*, my carbon footprint versus various averages (in lbs. of CO2 per year):
Before solar: 18,654
After going solar: 17,199
CO2 reduction from solar: (1,455)
Average Californian: 22,941
Average American: 32,607
Average Global Person: 8,750
Not quite there, but starting to do my part. Maybe my next car will be a hybrid.
*Note - All calculations are based on PG&E's assumptions. PG&E claims to have an emissions rate (electric) of 0.575 lbs CO2 per kWh which is very low. I think average base load for California is 1.3 lbs CO2 per kWh and my SunPower monitoring system has an even higher assumption of 1.7 lbs CO2 per kWh. If your utility has a higher carbon emissions rate than PG&E, then your carbon footprint could be significantly higher and the impact of installing solar panels even greater.
