Steam engines and diesel engines are heat engines. An electric motor isn't an engine - it converts and transfers power, but doesn't actually create it.

Steam engines presently produce more power than all other types of engines combined. Most steam engines take the form of the steam turbine engine. The steam turbine is responsible for generating about 86% of the electric power used on this planet.

Reciprocating steam engines are still in use for limited applications, but are generally considered obsolete. Steam engines, either the piston or turbine type were used on most big ships until recently, and there are still a few steam locomotives about.

Coal fired steam driven power stations are still in use
