Transit agencies can help individuals reduce energy use by providing alternatives to travel in personal vehicles. They also consume significant amounts of energy providing this service. Reducing energy consumed by transit agencies can lower costs, reduce environmental impacts, and improve customer service. This study describes how transit agencies are reducing energy use and is based on survey responses from 51 diverse agencies across the country, a literature review of a variety of academic and professional publications, and case examples of four agencies. Transit agencies use energy to power, clean, maintain, and repair their revenue and nonrevenue vehicles. They also use energy to provide heating, cooling, and electricity to stations, stops, administrative buildings, garages, and other facilities. Finally, agencies indirectly consume energy embodied in construction materials, water, and waste. These different uses of energy represent opportunities for transit agencies to reduce their energy use and expenditures through strategies that range from the very simple (such as switching to more energy-efficient light bulbs) to more complicated (such as operating a wind farm on agency right-of-way). These strategies can reduce both an agency's costs and its environmental footprint, and some can also improve service quality. |
