If used only for power generation they are more efficient than a gasoline powered generator and no more efficient than a diesel powered generator, but, they can be more efficient than a diesel if constantly operated at high loading.

If you use the exhaust heat for some other purpose such as refrigeration or evaporating water, or general heating purposes, they can be twice as efficient as a diesel generator.

Small units are generally less efficient than large units. A turbine can run far longer than a diesel before maintenance is required but is not happy with many starts. They are not a great idea for the weekend user.
