This Senate resolution officially designates October 1, 2025, as "Energy Efficiency Day." The designation serves to celebrate the substantial economic and environmental advantages that have resulted from both private sector innovation and federal energy efficiency policies. The resolution highlights that improvements in energy efficiency technologies and practices, alongside United States policies enacted since the 1970s, have led to over $1 trillion in annual energy cost avoidance. Energy efficiency has garnered bipartisan support in Congress and across administrations for more than 50 years, with numerous legislative acts contributing to its advancement. These efforts have enabled the United States to more than double its energy productivity since 1980, meaning twice the economic output per unit of energy consumed. The energy efficiency sector currently employs over 2.3 million individuals in the United States, demonstrating its significant economic impact. Furthermore, cutting energy waste saves American consumers billions of dollars annually on utility bills, and federal facilities have seen nearly a 50 percent reduction in energy intensity. The resolution concludes by calling on the people of the United States to observe Energy Efficiency Day with appropriate programs, ceremonies, and activities.
