State-level legislation can be an excellent tool for advancing energy efficiency. SWEEP actively engages in the legislative process in all the southwest states, with efforts ranging from researching and writing bill language, to building coalitions in support of energy efficiency legislation, to testifying at committee hearings. Through these ongoing efforts, support for energy efficiency and clean transportation across the Southwest continues to grow.
