The USA’s top 10 renewable energy firms by revenue are Constellation Energy Corporation, Duke Energy Corporation & The Southern Company
Renewable power generates about 20% of all electricity generated in the USA — a steadily rising number, according to the Office of Energy Efficiency and Renewable Energy. Relative to energy output, 9.2% is wind-based, 6.3% is hydropower-based, 2.8% solar-based, 1.3% biomass-based and 0.4% geothermal-based. As renewable energy provides for more and more generation of energy, firms that might historically generate energy from non-renewable sources are transitioning as well, striving towards net zero greenhouse gas emissions consistent with national targets, and taking the global transition as a chance to enhance their products and build globally-leading technologies.
These top 10 renewable energy firms in the USA are ranked by revenue and are some of the firms that are storming the emerging renewable energy industry.
