Building a solar-powered future

Read the full story from the National Renewable Energy Laboratory.

The next 30 years of solar energy is likely to look very different than the past 30. Photovoltaics (PV) and concentrating solar power are likely to continue to grow rapidly—the National Renewable Energy Laboratory (NREL) projects solar energy could provide 45% of the electricity in the United States by 2050 if the energy system is fully decarbonized—and technology costs are projected to continue to decline.

But in the coming decades, the evolution of solar energy technologies could be defined more by how they interact with other energy technologies, like wind and storage. Changes across the wider energy system, like the increased electrification of buildings and vehicles, emergence of clean fuels, and new commitments to both equitability and a more circular, sustainable economy, will shape the future of solar energy. These are just some of the key findings of the Solar Futures Study, published by the U.S. Department of Energy Solar Energy Technologies Office and written by NREL. The study is based on extensive analysis and modeling conducted by NREL and synthesizes analysis across many domains to provide a balanced and rigorous assessment of the future of solar power.
