The Potential of Hybrid Clean Energy Systems to Advance Energy and Climate Justice

This briefing discusses how hybrid clean energy systems—combining local renewable resources like solar with baseload resources like geothermal—can address energy and climate injustices in marginalized communities. It highlights the disproportionate impact of extreme heat and aging gas infrastructure on low-income communities of color and evaluates policy interventions and technical models, such as a geothermal pilot in Massachusetts, to improve energy security and resilience.

• Low-income communities and communities of color face disproportionate risks from climate-driven extreme heat and aging energy infrastructure. In New York City, premature mortality linked to hotter summers is projected to increase by 47 percent to 95 percent by mid-century. Furthermore, residents with the highest energy burdens may see air conditioning costs rise to between 6.1 percent and 8 percent of their income.
• Research in Massachusetts indicates significant inequities in the distribution and repair of gas leaks. Areas populated by people of color, renters, lower-income residents, adults with lower education levels, and limited English-speaking households have higher leak densities and experience slower repair times, even when using the same utility.
• Financial incentives targeting lower-income consumers and solar leasing options have proven effective in increasing rooftop solar adoption in underserved communities. Specifically, leasing increased quarterly installations by 1.5 adoptions per 1,000 low- and moderate-income households, while targeted incentives increased them by 0.7 adoptions per 1,000 such households.
• A pilot project in Massachusetts is testing the replacement of leaky gas distribution networks with connected ground-source heat pump systems, known as the "geo-grid" model. This approach utilizes existing rights-of-way to reduce costs and eliminate methane emissions from gas combustion, potentially offering a scalable framework for gas utilities to transition to clean energy.
• Hybrid renewable energy systems that pair intermittent resources (like solar) with weather-independent baseload resources (like geothermal) can enhance energy security and resilience. A study of 20 hypothetical houses in Zagreb, Croatia, found that such hybrid systems reduce solar power curtailment and allow excess solar power to recuperate geothermal reservoir temperatures, improving seasonal performance.
• Transitioning to distributed, smart, and integrated hybrid energy systems requires advanced information and communication technology to process data for short-term decision-making and long-term planning. While these systems can maximize energy output and reduce emissions, they may require new market frameworks to manage high up-front costs.
