The Weatherization Assistance Program enables low-income families to permanently reduce their energy bills by making their homes more energy efficient. During the last 30 years, the U.S. Department of Energy 's (DOE) Weatherization Assistance Program has provided weatherization services to more than 5.6 million low-income families.

By reducing the energy bills of low-income families instead of offering aid, weatherization reduces dependency and liberates these funds for spending on more pressing family issues. On average, weatherization reduces heating bills by 32% and overall energy bills by $358 per year at current prices. This spending, in turn, spurs low-income communities toward job growth and economic development.
