This applys mainly to American subs. All of our subs are propelled by either eletric motors or steam turbines.
Diesel subs have an angine which is used to turn a generator and power the eletric motors. The diesel also charges the battery for use while submerged below periscope depth.
Nucleat powered subs use a reactor to heat water in steam generaters which are used to power the main engines and turbine generators. They also have a diesel generator and battery for emergency power. A small DC motor can also be used when running on the battery.

Today there are two "prime-movers":
Nuclear - A reactor creates steam which turns a turbine which turns a gear-reduction system (transmission) which turns the propeller-shaft.
Diesel - A diesel engine runs (when surfaced or snorkeling) and either turns a gear-reduction system, or (more commonly) a Generator which supplies electric power to an electric motor which turns the propeller-shaft. Diesels run on batteries when submerged.
BOTH prime-movers also operate an additional generator to provide the "house-power" for ships electrical systems.

Nuclear subs are powered by a small nuclear power plants right on the sub.
Diesel subs are powered by diesel above the water and battery below water surface.

If its atomic one, than by nuclear energy, others are powered by diesel
