Naomi Davis won’t lose her faith in the earth. At a recent community meeting in Chicago’s South Side she wanted to drive the point home — that the city’s Black community will not be left out of the new, emerging green economy.

To do it, she’s betting on energy trapped deep below the surface of the earth known as geothermal, which could be an answer to heating and cooling homes more efficiently and a path to building decarbonization. 

Davis heads Chicago’s Blacks in Green, an environmental justice group which has dedicated the past 17 years to figuring out the blueprint for self-sustaining, climate-resilient Black communities everywhere. 

“We’re hit first and worst, resourced least and last, and we contribute the least to global warming,” said Davis.

Last year the group won the support of the Biden administration with the Environmental Protection Agency awarding a five-year $10 million grant. The money will enable Blacks in Green to work with other environmental justice communities in the Midwest to take advantage of historic funding made available through the Inflation Reduction Act.

The Chicago organization is already beginning to work on sustainability projects in Cleveland.

Back home, Davis is focused on carbon-free energy: how to generate it, how to make it affordable, and how to get it out of the ground. Her aim is to ensure that her community won’t be left behind as the rest of the city becomes sustainable.

“We’re not going to be the ones left on the gas bills with the spiraling costs and the technology that is continuing to pollute us,” she said, adding for emphasis, “No.”

In 2023, Blacks in Green was one of 11 community partners across the country chosen by the U.S. Department of Energy to design and develop a community geothermal heating and cooling district. That will mean building out a shared geothermal network across four city blocks containing more than 100 multi-family and single-family homes.

The goal is to decarbonize buildings and reduce energy costs for families. To get there, Blacks in Green received nearly $750,000 to kick off the initial phase of the pilot, which includes hosting community meetings and determining household needs.

Davis said Chicago’s West Woodlawn neighborhood — located about 9 miles south of the city’s downtown — is ready to experiment with geothermal energy.

But at the Blacks in Green community meeting, neighbors like Debra Gay and her mother Retta Ford have questions about what exactly it’ll take to bring geothermal energy to the South Side.

“Given that our city lots are so tightly spaced, how would you do that for an existing home and will that create some disruption?” asked Gay.

Ford, Gay’s mother, worried whether the project could destabilize the foundation of older homes.

Not necessarily, according to Andrew Barbeau, president of the Accelerate Group, a clean energy consulting firm working alongside Blacks in Green to design and deploy the geothermal pilot project.

The key to geothermal in these old neighborhoods: the alleys.

“Out in front, you got water, you got gas, you got sewer, and other things are alleys,” Barbeau said. “There’s nothing under that ground.”

The plan is to leverage the earth underneath the alleys behind homes and businesses to build out a community geothermal system. That will mean a series of deep, 400-foot holes that pipe water into the ground, absorb the temperature of the earth, and bring it back up to the surface to make use of it.

By building the community heating system beneath the alleys, the project sidesteps the major challenge that major American cities like Chicago face: lack of open, workable space. Once installed, buildings along the alleyway can connect to the underground heating system at their own convenience.
