Weatherization Program Facts

The Division of Energy administers federal funds to a statewide network of 18 local weatherization agencies. Allocations to these agencies are based on the percentage of the state's total low-income households within each service area. The agencies provide weatherization services and energy efficiency and safety education to eligible clients. The program reduces clients' energy bills while stimulating the state and local economy. The agencies use their own crews or contract with local businesses to perform the weatherization work. Most products are purchased from local and regional companies. Indirectly, through an economic multiplier effect, weatherization funds are used and reused, stimulating the state's businesses, economy and job creation.

  • Since 1977, more than 193,000 Missouri homes have been weatherized through the Weatherization Assistance Program.
  • Weatherization reduces residential and power plant emissions of carbon dioxide by 2.65 metric ton/year per home1.
  • Weatherization decreases national energy consumption by the equivalent of 24.1 million barrels of oil annually1.
  • Weatherization saves, on average, $437 per house in heating and cooling costs annually at current prices1.
  • Nationally, the Weatherization Assistance Program supports 8,500 jobs and provides weatherization services to approximately 35,000 homes every year.²

Primary funding for Missouri's weatherization efforts comes from the U.S. Department of Energy's Weatherization Assistance Program:

Funding is also provided through a transfer for federal Low Income Home Energy Assistance Program (LIHEAP) funds from the Missouri Department of Social Services. In addition, through agreements made with the Division of Energy in rate adjustment cases and other regulatory matters, further funding is provided by the following companies to weatherize additional homes in their service areas:

  • Ameren Missouri
  • Empire District (through Liberty Utilities)

These funds are administered by the Missouri Department of Natural Resources' Division of Energy.
