How did legislation on energy efficiency and utility restructuring help Texas meet air quality regulations. Motivated by both economic and environmental goals, Texas state officials, regional U.S. Environmental Protection Agency (EPA) officials and, ultimately, the Texas Legislature were convinced of the need to address air quality issues using renewable energy (RE) and energy efficiency (EE). The Department of Energys (DOE) Office of Energy Efficiency and Renewable Energy (EERE) provided technical assistance on utilizing RE and EE technologies to meet legislated goals. This fact sheet outlines Texas unique approach to improving air quality through both stringent policies and innovative analytic methods.
