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 ** grams of COâ‚‚ per kilowatt hour generated, while hydropower had an average emission intensity of **** grams of COâ‚‚. In contrast, coal power plants emit roughly *** kilogram of COâ‚‚ per kilowatt hour produced.
COâ‚‚ emissions from renewable-based power sources are associated with emissions during the manufacture process, as well as transportation and maintenance.
