This chart shows the number of transit buses in use in the United States, broken down by fuel type, from 1996 to 2009. In all years shown, diesel buses represent the largest portion of total buses, with natural gas buses a distant second. The share of alternative fuel buses has risen from 4% of the buses in 1999 to 30% in 2009. Over the same decade, natural gas buses have risen from 3% to 18% of all purchases. This increase is largely due to the favorable economics and clean air benefits of natural gas in transit bus applications.
**Biodiesel was counted in the "other" category until 2008.
