Big renewable energy companies are leading the momentum for the global transition to a cleaner, more sustainable energy future. According to Blackridge’s Global Renewable Energy Market Report, renewable energies are projected to make up more than 35% of the world’s energy mix by 2040. 

In 2024, renewables accounted for the largest share of growth in total energy supply, with 38% surpassing natural gas at 28%, coal at 15%, oil at 11%, and nuclear at 8%. To meet this growing demand, top renewable energy companies in the world are investing heavily in solar, wind, hydro, and other renewable projects, targeting to achieve 100 GW of gross installed renewable power capacity by 2030.

With so many players driving the momentum, it’s important to recognize the leaders shaping the global renewable energy market. In this blog, we have covered the top 10 renewable energy companies ranked based on their installed renewable energy capacity as of 2025.
