Battery Electric Buses: Benefits Outweigh Costs

The document examines the transition from diesel to battery-powered electric buses (BEBs), highlighting that while upfront costs remain higher, BEBs offer lower operating and maintenance costs, higher fuel economy, and zero tailpipe emissions. It details the current global deployment—dominated by China—and the growing adoption in U.S. cities like Los Angeles and New York. The text also discusses the health risks of diesel exhaust, particularly for children, and outlines available federal and state funding mechanisms, such as FTA grants and Volkswagen settlement funds, to support the transition.

• Battery-powered electric buses (BEBs) have higher initial purchase prices than diesel buses, but offer significantly lower long-term operating and maintenance costs. In 2015, a 40-foot diesel bus cost approximately $445,000 compared to $770,000 for a BEB; however, powering vehicles with electricity is about 2.5 times cheaper than using diesel.
• BEBs demonstrate superior energy efficiency and lower maintenance requirements than internal combustion engine buses. The U.S. National Renewable Energy Laboratory found BEB fuel economy to be five times higher than that of diesel buses on equivalent routes, and electric motors are more efficient with fewer moving parts.
• Global adoption of electric buses is heavily concentrated in China, though projections suggest a rapid worldwide shift. As of the report, approximately 386,000 electric buses were deployed globally, with 99 percent located in China and less than 0.1 percent (350 buses) in the United States. Bloomberg New Energy Finance estimates that 84 percent of new municipal buses sold will be electric by 2030.
• Several major U.S. jurisdictions have set target dates to transition their entire bus fleets to BEBs, including Los Angeles County (by 2030), San Francisco (by 2035), and both Seattle and New York (by 2040).
• The transition to BEBs provides critical health benefits by eliminating tailpipe pollution, particularly for vulnerable populations. Diesel exhaust is a known carcinogen linked to respiratory diseases like asthma; children are especially at risk because their respiratory systems are still developing and they inhale more air per pound of body weight than adults.
• Financial support for BEB adoption comes from various federal and state sources, including the Federal Transit Administration (FTA) and the California Air Resources Board. The FTA awarded $264 million in grants to 139 projects in April 2018, and the California Air Resources Board approved $208 million for low- and zero-emissions fleets. Additionally, states are utilizing Volkswagen settlement money for BEB purchases.
• Performance issues have been reported with BEBs from manufacturer Byd in California, Colorado, and New Mexico, including batteries depleting faster than advertised, stalling, and difficulty climbing hills.
