This chart depicts the number of transit buses in use in the United States, categorized by fuel type, from 2007 to 2023. In all years shown, diesel buses represent the largest portion of total buses, with natural gas buses a distant second. Hybrid buses are the fastest growing category as they have increased more than eight times from 2007 to 2021. The increase in both natural gas and hybrid buses is largely a result of favorable economics in the transit bus application.
