Wind and hydropower are among the cleanest sources of electricity generation, based on lifetime carbon emissions. During its lifespan, wind power plants were estimated to generate around 10 grams of CO₂ per kilowatt hour generated, while hydropower had an average emission intensity of four grams of CO₂. In contrast, coal power plants emit roughly one kilogram of CO₂ per kilowatt hour produced.
CO₂ emissions from renewable-based power sources are associated with emissions during the manufacture process, as well as transportation and maintenance.
