The main purpose of this legislation is to update the Farm Security and Rural Investment Act of 2002 by recognizing waste energy recovery as a valid source of renewable energy. The goal is to promote the use of energy that would otherwise be wasted in various processes, thereby encouraging more sustainable energy practices. Key provisions of the legislation include the addition of waste energy recovery to the list of renewable energy sources defined in the Act. Specifically, it modifies existing language to include waste energy recovery alongside hydroelectric energy.
