Energy efficiency improvements and distributed renewable energy systems benefit the utility grid by reducing demand
Low-income households can particularly benefit from energy efficiency improvement programs.
Federal, state, and private programs are available to assist residential and commercial consumers with paying for energy saving technology.
As demand for electricity is expected to increase, the electric grid must be able to meet this need (DOE 2024). Installing new electricity generation and expanding the grid transmission system meet this demand by increasing supply. Investments in energy efficiency and distributed renewable energy, such as residential solar energy, small wind turbines, or battery storage systems, improve grid reliability by reducing overall demand. Energy efficiency improvements save customers money on electric bills and delay installation of new energy generation systems. This delay provides long-term savings to both utility companies and consumers.
See our Science Note on Grid Reliability to learn more about the evolving power system and ensuring the reliability of the U.S. power grid.
Property Assessed Clean Energy (PACE) is a model to finance energy efficiency improvements and renewable energy systems authorized by MO statute (RSMo 67.2800-67.2840). 3 districts administer the program to participating MO communities.
Residential energy efficiency improvements can require a high upfront investment that may be inaccessible. Low-income households (MU Extension 2024, Rose 2020, Eisenberg 2014):
Programs assist consumers in paying for upgrades or in spreading out the investment over time with accessible financing. Major programs available to Missourians that serve a residential audience are listed in Table 1.
