The Low Income Home Energy Assistance Program, or LIHEAP, is a federal program in the United States designed to help low-income households manage their energy costs. It provides financial assistance for heating and cooling bills, as well as emergency services for those facing energy crises. LIHEAP is administered by state and local agencies, which determine eligibility based on income and household size. The program aims to ensure that vulnerable populations, such as the elderly and disabled, have access to essential energy services, promoting health and safety during extreme weather conditions.
