In a gas turbine, large volumes of air are compressed to high pressure in a multistage compressor for distribution to one or more combustion gases from the combustion chambers power an axial turbine that drives the compressor and the generator before exhausting to atmosphere.
Diesel is a reciprocating engine which uses diesel fuel (distillate) for high-speed or heavy oil (residual for mid- and low-speed engines.
Diesel generators play an important role as local reserve, particularly where the transmission tie is radial or of marginal reliability for other reasons.

The 60-foot mass-transit vehicles, which are more expensive than standard diesel buses, deliver up to 60 percent greater fuel economy and can reduce emissions by as much as 90 percent, GM said.
Hybrids draw power from two energy sources, typically a gas or diesel engine combined with an electric motor.
One of the ways the buses conserve fuel is by storing electricity generated when they brake, then using that electricity as a power source when the bus leaves from a stop.
