eng.carbon-footprint-electricity Calculator
Calculates carbon footprint from electricity consumption using the regional grid emission factor (kg CO₂/kWh). Grid emission factors vary from near zero (Iceland, Norway on hydropower) to 1.0+ kg CO₂/kWh (coal-heavy grids) — location is the dominant factor in electricity carbon footprint.
Inputs
Consumption Kwh Year
Reference formula or conversion factor shown for context.
Grid Emission Factor Kg Kwh
A multiplier applied in the calculation.
Renewables Pct
Capacity to do work (J or kWh). Conserved — converts between forms but total stays constant in a closed system.
Results
carbon footprint (tCO₂e/year)
Sample size or count used in the calculation.
adjusted for renewables (tCO₂e/year)
Sample size or count used in the calculation.
trees needed to offset
Sample size or count used in the calculation.
grid EF reference
Sample size or count used in the calculation.
CO₂ = kWh × EF
