Decarbonising electricity generation will be critical if we are to achieve deep cuts in global greenhouse gas emissions. Despite their negative environmental and health impacts, fossil fuels still dominate the electricity generation mix in many countries. However, many low- or zero-carbon electricity generation technologies are available, including renewable energy sources such as hydro, wind, solar, biomass and geothermal power as well as nuclear power. The carbon intensity of electricity generation can be decreased by scaling-up investment in low-carbon energy sources, switching from highly carbon-intensive fossil fuels such as coal to less carbon-intensive alternatives such as gas, and increasing use of carbon capture and storage (CCS) technologies. Emissions reductions can also be achieved by curbing electricity demand via increased efficiency and smarter power grids.

This ratio is expressed in grammes of CO2 per kWh. It has been calculated using CO2 emissions from generation of electricity divided by output of electricity. The CO2 emissions include emissions from fossil fuels, industrial waste and non-renewable municipal waste that are consumed for electricity generation in the transformation sector and the output includes electricity generated from all fossil and non-fossil sources (excluding pumped hydro). As a result, the emissions per kWh can vary from year to year depending on the generation mix.
Shows the total number of GWh generated by power plants.
Output of electricity produced based on fossil fuels divided by total output of electricity expressed as a ratio. Fossil fuels include coal, oil shale, peat and peat products, oil and natural gas.
