CO₂ Emissions Avoided

This formula estimates how much carbon dioxide is avoided when electricity comes from a clean source instead of the regular grid mix. You multiply the amount of clean electricity generated by the grid’s emissions factor, which represents how much CO₂ would have been produced for each kWh from fossil fuels. The result tells you the emissions that were not released because the cleaner energy replaced grid electricity.

Use this when comparing solar, wind, hydro, or other low-carbon electricity against standard grid power. It is useful for sustainability reports, carbon accounting, and estimating the climate benefit of a renewable energy project.

• Using watts instead of kilowatt-hours for E
• Mixing up the emission factor units and not using kg of CO₂ per kWh
• Treating the result as actual emissions produced instead of emissions avoided
