Energy Consumption Patterns in Arizona

Recent studies on energy consumption during DST in Arizona show modest savings of approximately 0.8% in electricity usage. However, these savings are offset by increased gasoline consumption as people take advantage of extended daylight for travel and recreation. The net energy impact remains a subject of ongoing research and debate among policy makers.
