Modifies certain provisions relating to the renewable energy

HB 2657 establishes foundational definitions to advance renewable energy use in Missouri state buildings. It defines key terms like "renewable energy source" (including solar, wind, and geothermal), "state building," and "substantial renovation" to create clear standards for energy efficiency. These definitions directly affect state agencies, public buildings, and contractors working on state construction or renovation projects by setting requirements for renewable energy integration and energy efficiency reporting. The bill creates the framework for future implementation of energy-saving measures but does not yet mandate specific actions or funding.
