The first question on the EPA Household Carbon Emissions calculator is to select my type of household heating:
- Natural Gas
- Fuel Oil
We heat our home with locally produced wood pellets. Since I cannot answer the first question correctly, the entire calculator fails.
I used this one at the University of California, Berkeley and it estimates our household annual carbon emissions at about 20 tons of CO2e per year, or 62% less than the average American home.
I used a different one in the past (link not saved) and it estimated our usage at around 16 -17 tons, and said the average home was about 40 tons/year, which seems inline with the UCB calculator.
