Carbon footprint

The carbon footprint of electric power and gas production refers to the amount of greenhouse gases, mainly carbon dioxide (CO2), released into the atmosphere during this production. It is therefore used to measure its environmental impact. Low carbon footprints are usually associated with production from renewable energy sources such as solar panels or wind turbines, where CO2 emissions are minimal. In contrast, electric power generation from fossil fuels such as coal or oil has a high carbon footprint. The carbon footprint of electric power generation can be reduced by increasing efficiency and by an appropriate mix of sources.
