Diesel-fueled buses are a big part of transportation in
large cities and likewise are contributing pollution to the environment. Some
cities have tried alternative bus fueling techniques, however, some methods have
failed while some are relatively new. This article discuses the costs and
benefits to using different fuel technologies in the Greater London area. Several different bus types were used to test
out the costs and benefits and out of all of them the Hybrid electric buses
(HEB) had most improved air quality, however, there is uncertainty as to how
reliable they are for long-term use, which could cause high costs for repair (Chong U. et al. 2014).
