These tools can help calculate performance of building systems like windows and shades, help consumers and builders pick the best windows for a variety of applications and much more.

Clean Energy to Communities Awardees Announced

September 27, 2023

The U.S. Department of Energy (DOE) has announced up to $25 million to help six teams across the nation develop affordable, equitable, and reliable clean energy systems in their communities. The funding comes through the Clean Energy to Communities (C2C) partnerships program, an initiative designed to support local decarbonization strategies.

Lawrence Berkeley National Laboratory (Berkeley Lab) is among five DOE national research labs participating in the Clean Energy to Communities (C2C) program, which is led by the National Renewable Energy Laboratory. The six projects, which are detailed here, span Illinois, Colorado, Pennsylvania, New Jersey, the Delaware Valley, Alaska, and Hawaii.

Local governments, electric utilities, and community-based groups will work closely with experts from DOE’s national laboratories on their projects, using $8 million in award funding and up to $17 million in technical assistance for research, modeling, and deployment. The projects include efforts to reach net-zero transportation emissions, expand renewable energy generation, and more.
