Renewable energy, once a niche segment of the broader energy industry, is growing rapidly to become an important source of power in many regions and nations across the globe. Companies within the sector provide a variety of clean energy including solar, wind, hydroelectric, geothermal, and biomass. The largest renewable energy companies are headquartered in Spain and Denmark, but other big players are based in China, the U.S., and Canada.
These are the 10 biggest renewable energy companies by 12-month trailing (TTM) revenue. Some companies outside the U.S. report profits semi-annually, so the 12-month trailing data may be older than it is for companies that report quarterly. This list is limited to companies that are publicly traded in the U.S. or Canada, either directly or through ADRs. All figures are as of Dec. 27, 2021.
Some of the stocks below are only traded over-the-counter (OTC) in the U.S., not on exchanges. OTC stocks often carry higher trading costs than equities listed on exchanges. This can lower or even outweigh potential returns.
Key Takeaways
