The LIHEAP & Extreme Heat Hub from the U.S. Department of Health and Human Services provides key insights into how the Low-Income Home Energy Assistance Program (LIHEAP) supports vulnerable communities during extreme heat. The platform features interactive maps, data, and stories showing how LIHEAP funding helps low-income households afford energy for cooling. It also highlights the correlation between heat exposure and energy insecurity. As climate change increases the frequency and severity of heatwaves, this tool demonstrates how federal assistance plays a critical role in heat resilience, public health, and energy justice for at-risk populations across the U.S.
