Who We Serve
Community-Based Organizations
CEG collaborates with community-based organizations to implement clean, resilient power solutions, providing technical assistance to dozens of organizations each year to protect community members during power outages. CEG develops introductory guides and fact sheets to help address knowledge gaps and build local capacity.
Environmental Justice Advocates
CEG partners with environmental justice advocates across the country to fight for clean alternatives to polluting fossil power plants and combat harmful false solutions. Partnerships include collaborative initiatives with the PEAK Coalition in New York City and the Clean Peak Coalition in Massachusetts.
State and Local Government Leaders
CEG works with state agencies to advance equitable clean energy policy, like climate resilient energy codes for affordable housing and innovative distributed energy storage programs. CEG assists states and municipalities in developing resilient power solutions for community-serving facilities, including community centers, fire stations, and affordable housing.

Green hydrogen and ammonia are making waves in the shipping industry; will they do more harm than good?
In early March, a large ship made its way into Southampton’s port on the south coast of the UK. A green circle and the words “leading the way to real zero” plastered on the side sent a message: this isn’t your average ship. Named “Green Pioneer” and owned by Australian mining and green hydrogen giant…
Still Considering Solar and Storage? Run, Don’t Walk.
In the six weeks between the release of the House of Representatives’ version of the “One Big Beautiful Bill Act” (OBBBA) and President Trump’s signing of the final legislation, a decade of progress towards achieving cleaner, more reliable energy infrastructure was reversed. The speed with which the bill passed, combined with the severity of changes…
What Nonprofits Need to Know about the Investment Tax Credit in 2025
In the July 2025 “One Big Beautiful Bill Act,” Congress terminated key aspects of the Investment Tax Credit (ITC) for solar and wind projects and created barriers for projects pursuing energy storage and other zero emissions technologies. Under the revised ITC guidelines, solar and wind projects must begin construction by July 4, 2026, or be…
Hydrogen Got a Reprieve in the Reconciliation Bill, but It Needs More Than That to Be Cost Competitive
Utilities in at least 18 states are developing “hydrogen-ready” combined cycle (CC) or combustion turbine (CT) power plants. These plants are part of a larger shift towards maintaining a reliance on fossil fuel infrastructure, both by building new plants and keeping old ones online, spurred by a pro-coal and gas administration and fearmongering around grid…
Resilient Power in the Wake of Hurricane Helene
One of the things I cherish most about Western North Carolina is its patchwork of small, close-knit communities nestled among mountains and valleys, all interconnected by an endless web of creeks and streams. Many of these communities are rural and secluded, a contrast to the region’s population center of Asheville, where I live. Although beautiful…
Hydrogen production’s unbreakable ties to fossil fuels in the US
For the past few years, hydrogen has been proposed as a method of reducing emissions in almost every sector, from energy production, to transportation, to manufacturing. This has led to a boom in proposed hydrogen production plants, mainly focused on so-called low carbon hydrogen. But hydrogen production isn’t new. This gas has long been used…
Long-Duration Energy Storage: What Is It, Why Do We Need It, and When Will It Get Here?
There has been a lot of excitement in the energy world around the promise of long-duration energy storage (LDES) and emerging technologies challenging the dominance of lithium-ion batteries. National and international consortiums have sprung up to advance the sector, LDES businesses have surpassed billion-dollar investment milestones, and leading states have established the first LDES procurement…
U.S. Utilities Can Blend Hydrogen in their Gas Supply Without Informing Customers
Across the country, gas utilities are proposing to inject hydrogen into residential and industrial gas pipelines, framing the move as a climate solution. But scientific analyses have found that hydrogen blending is an expensive and inefficient way to decarbonize buildings—and may actually increase health risks and greenhouse gas emissions. Studies show that mixing hydrogen with…
New Energy Code Sets a National Precedent for Climate Resilient Affordable Housing
As climate change intensifies and extreme weather events become more frequent, the need for resilient, energy-secure housing has never been more urgent. In response, a team led by Clean Energy Group has taken a groundbreaking step by developing a climate resilient energy code for multifamily affordable housing — a first-of-its-kind framework aimed at ensuring that…
The Cape Light Compact’s Equity-Centered Model for Solar+Storage+Electrification
Since 2019, Massachusetts utilities have offered battery performance payments to wealthier customers, but without any equity provisions to help low-income residents access the program. Now, an innovative new model combining solar PV and energy storage with electrification and traditional efficiency measures is providing new opportunities for some low- and moderate-income households to fully decarbonize their…
