A majority of U.S. electric utility customers are concerned about the long-term availability of electricity, but they continue to support clean energy initiatives, according to the 2026 U.S. Sustainability Index from JD Power. "For many customers, sustainability is no longer just about being 'green,'" said Ramah Vaughn, director of utilities intelligence at JD Power. Customer Awareness Continues to IncreaseAccording to the study, customer awareness of utility sustainability goals has continued to rise, although overall awareness remains relatively low. Sustainability and EV Programs Linked to Customer SatisfactionThe report also found a relationship between sustainability performance and customer satisfaction. Among utilities with Sustainability Index scores at or above the industry average, 82% also ranked highly in overall customer satisfaction.
