The Department of Energy (DOE) Solar Energy Technologies Office (SETO) recently released its Solar Futures Study outlining solar energy’s pivotal role in transitioning to a carbon-free electric grid. The study finds that with aggressive cost reductions, supportive policies, and large-scale electrification, solar could account for as much as 40 percent of the nation’s electricity supply by 2035 and 45 percent by 2050. The ECS community will play a critical role in the technology advances required to make this vision a reality.
