How big will renewables be over the next 10 years?

By on July 12, 2021 0


The growth of clean energy is accelerating, both in the United States and abroad.

Last year, the world added a record over 260 gigawatts of renewable electricity capacity, nearly 50% more than in 2019, according to the International Renewable Energy Agency. The United States was one of the fastest growing markets, the agency said, adding 29 gigawatts of capacity, nearly 80% more than the previous year.

The United States now generates nearly 20% of its electricity from renewable sources such as wind, solar and hydro, while nuclear accounts for around 20%. The Biden administration, which aims to reduce carbon emissions by at least 50% by 2030, wants Congress to adopt its clean electricity standard, which predicts that 80% of U.S. electricity will come from clean sources by the end of the decade. To that end, the White House infrastructure proposal included billions of dollars in investments in renewable energy.

Can renewables become so important in the United States over the next decade? We asked three experts to step in: Kevin Book, managing director of Clearview Energy Partners in Washington, DC; Jesse Jenkins, assistant professor at Princeton University with a joint appointment to the Department of Mechanical and Aerospace Engineering and the Andlinger Center for Energy and the Environment; and Leah Stokes, assistant professor of political science at the University of California at Santa Barbara.
