The City of Seattle is working with Metro to improve the electric bus routes. Metro electric buses (also called electric trolley buses) are powered by electricity from Seattle City Light, which produces zero net climate-altering emissions. In addition to being virtually carbon neutral, electric buses are approximately twice as energy efficient as diesel, diesel hybrid, or natural gas fueled buses.
The County’s electric buses are due for replacement in 2013-14. King County is considering the replacement of electric buses with diesel hybrid vehicles and will begin a detailed analysis of trolley alternatives in 2010. Decisions will be needed in 2011 for purchasing a new fleet in 2013-14.
