Enter your annual kWh usage and grid emissions factor to see your electricity-related carbon footprint.
Electricity is typically 25-40% of a U.S. household's total carbon footprint — the rest comes from transportation, heating fuel, and consumption.
Your home's electricity carbon footprint depends entirely on two things: how much you use, and how clean your regional grid is — a household using 10,000 kWh in a hydro-heavy state can have a fraction of the footprint of the same usage in a coal-heavy one. Solar directly reduces this number; see exactly how much with the CO2 savings from solar calculator.
Generation mix varies enormously by region — a kWh in a state relying heavily on coal or gas carries several times the emissions of the same kWh in a state with more hydro, nuclear, or wind.
No — this covers only the electricity consumed to operate your home, not embodied emissions from manufacturing appliances or the home itself, which fall under a separate lifecycle accounting.
