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

HR 1520 reauthorizes the Energy Efficiency and Conservation Block Grant Program through 2028 with $3.5 billion annually. It expands eligible uses to include infrastructure for alternative fuels (like hydrogen or electric vehicle charging) and projects that diversify energy supplies. State and local governments would receive grants for initiatives such as district heating systems, distributed energy resources, or fuel delivery infrastructure. The bill explicitly allows funding for projects that expand alternative fuel access, building on the 2007 Energy Independence Act framework. This represents a concrete policy update to modernize program eligibility and funding levels.
