To amend the Energy Independence and Security Act of 2007 to reauthorize the Energy Efficiency and Conservation Block Grant Program, and for other purposes.

This bill reauthorizes the Energy Efficiency and Conservation Block Grant Program , amending the Energy Independence and Security Act of 2007 to bolster energy initiatives. It authorizes an appropriation of $3,500,000,000 for each of fiscal years 2026 through 2030 to fund the program, with a small percentage allocated for administrative costs. The legislation expands the program's core purpose to explicitly include diversifying energy supplies and facilitating the use of alternative fuels . It broadens the permissible uses of funds to cover the deployment of energy distribution technologies that significantly increase energy efficiency or expand access to alternative fuels, such as distributed resources and alternative fuel infrastructure. Furthermore, competitive grants under the program can now specifically support projects aimed at expanding the use of alternative fuels.
