Unfortunately, the link didn't make it with the above post, so I'll give it a shot. The diesel electric propulsion system uses a diesel engine(s) to turn generators which in turn power electric motors that turn a drive (or prop) shaft. This differs from other hybrid propulsion systems that require batteries (added weight plus replacement costs) to store the electricity. The advantages of diesel electric propulsion systems include reduced noise, increased efficiency, greater reliability due to fewer moving parts, less space, lighter, etc. These systems are now making their way into smaller applications such as pleasure craft. Hope that helps. new answer the same system is also used extensively on train locomotives. you see quite oten 2 or 3 locos but only one puffing exhaust that one is generating electricity for generators on all 3 locomotives Another new answer: the term "diesel electric" also applies to non-nuclear submarines. When on the surface (or using a snorkel) the boats are powered by diesel engines, which also charge batteries to be used when the submarine is submerged. Diesel engines require oxygen so can't be used when the boat is submerged, and the engines are also noisy, when submarines need to be quiet.

Why are submarines hybrids?
All submarines have at least 2 methods of propulsion; with nuclear power, steam generated moves the turbines/main engines, and also makes electricity for battery storage in case of main propulsion failure (electric motor propulsion). A backup Diesel-Generator is also aboard for making electricity if the reactor is down. Diesel-Electric boats run on electric motors (battery powered) submerged, and on their diesel engines while surfaced.
Hybrid Buses?
The hybrid buses of today incorporate the normal internal combustion engine propulsion system along with the electric propulsion system. These hybrid buses are known for using diesel - electric fuel are are also referred to as hybrid diesel - electric buses. Recently studies have shown that these hybrid buses reduce greenhouse pollution by using small amount of biodiesel (20%) and relying more on electricity.

Why do boats have diesel generators?
Boats have diesel generator because they are highly efficient for boat propulsion.
What does AIP mean?
Air Independent Propulsion is abbreviated by AIP. These are a powerplant type used on advanced diesel electric submarines to increase their endurance, and further lower the risk of detection.
How does a diesel submarine recharge its batteries?
World War II submarines were powered by large electric motors. On the surface, the motors drew their power from diesel generators, not unlike how a diesel locomotive operates today. When submerged, the diesel engines could not be operated, and the motors drew their power from huge banks of electric batteries. After the batteries were drained of their power, the submarine would have to surface in order to run its diesel generators to provide propulsion and electric power to the submarine. During this period, the sub's batteries were recharged. Toward the end of World War II the submarine snorkel was invented, which gave a submarine the capability of running its diesel engines while submerged. The submarine was required to stay relatively close to the surface, but it was fully submerged with the exception of the snorkel mast. Nuclear powered submarines also have banks of electric batteries, but they are only used when the main propulsion plant and/or its steam-powered electric generators are disabled. When a nuclear-powered submarine's batteries are fully drained, they are recharged by the boat's diesel generator if its steam-powered electric generators are not available, or by the steam-powered electric generators when they becomes available. Just like a diesel-electric submarine, a nuclear-powered submarine must operate its diesel generator on or near the ocean's surface.
What do some submarines have in common with trucks?
Many of the early submarines ran on diesel engines. These were used when on the surface for propulsion and power, as well as charging the batteries. When they submerged, they ran on electric power from the batteries.

How many different types of submarines are there?
Propulsion-wise, there are 2 types - Nuclear Powered and Diesel-Electric. Class-wise, there are several: Fast-Attack Ballistic Missile Guided Missile (e.g., Tomahawk)
Is a car a electromagnetic energy?

What makes trains move?
A propulsion car, usually a locomotive today. The first trains used people power, horse power, and gravity. Sail power was even tried in the early 1800's in the US. Then steam locomotives, followed by diesel locomotives, followed by electric locomotives, - Today, electric is the most common for passenger trains with diesel the most common for freight trains. Today, some trains distribute their propulsion along multiple cars and don't need a locomotive (referred to as MU, for multiple unit).
