Clean Energy Program

About the Program

The U.S. energy system today is one of the largest emitters of greenhouse gases (GHGs) and health-damaging air pollutants. This system has other widespread environmental impacts, many of which disproportionately burden vulnerable communities. Reducing these impacts will require a significant shift towards renewable energy resources, such as wind and solar, to power the electricity sector. At the same time, we must electrify direct fuel end-uses, such as transportation and home heating and cooling, and rapidly increase energy efficiency across all sectors.

The Clean Energy Program’s work focuses on both the development of pathways to a high renewable energy future as well as analysis of the health, environmental, and equity impacts of our current energy system and the transition to clean energy. Together, these efforts allow us to develop approaches to mitigate greenhouse gas emissions from the power sector while simultaneously achieving health, environment equity, and resilience co-benefits.
