Did You Know?
The average US home produces about 7.5 tons of CO2 per year from electricity use alone.
Solar panels have a 25–30 year lifespan and continue producing clean energy well beyond their warranty.
The US social cost of carbon is estimated at $51/ton, meaning every ton of CO2 avoided saves society $51 in health and environmental costs.
