Whether you're evaluating a home solar installation, a business sustainability report, or a region's grid decarbonization progress, this calculator shows what share of total energy consumption comes from renewable sources.
Renewable% = (Renewable Energy Used / Total Energy Consumption) x 100
Example
400 kWh from renewables out of 1,000 kWh total consumption:
Renewable% = (400 / 1,000) x 100 = 40%
Why This Metric Matters
Many national and regional climate targets are expressed directly as a percentage renewable target for a future year - this makes the renewable energy percentage a directly comparable benchmark across households, businesses, and entire power grids, all measured on the same normalized scale regardless of absolute energy consumption size.
Common Renewable Sources
Solar photovoltaic, wind, hydroelectric, geothermal, and biomass are the primary renewable energy sources counted toward this percentage - the relative mix varies enormously by region based on local resource availability (a sunny, arid region favors solar; a windy coastal region favors wind; a mountainous region with rivers favors hydro).
