Carbon Intensity

Carbon intensity is a measure of how clean our electricity is. It refers to how many grams of carbon dioxide (CO2) are released to produce a kilowatt hour (kWh) of electricity. Electricity that's generated using fossil fuels is more carbon intensive, as the process by which it's generated creates CO2 emissions.


Low-carbon energy is energy that is generated using lower amounts of carbon emissions such as, wind, solar, hydro or nuclear power.
