I think they are all diesel except for naval vessels in some navies, and some ice-breakers in Russia.
Modern submarines are powered by a nuclear reactor. Others are powered by diesel engines while they are on the surface and batteries while they are submerged. The older ones that were powered by diesel and batteries had their limitations. While they were on the surface running on diesel engines they left a trail of exhaust smoke which gave away their position. When they were submerged and running on batteries they could only last so long and then they had to come to the surface, run the diesel engines and recharge the batteries. The submarines that are run by nuclear power do not have to resurface for a very, very long time.
Submarines are powered by diesel fuel (in the past) or more recently by nuclear reactors. Nuclear reactors provide advantages in range and in noise produced.

The Navy uses Nuclear Power to create steam. Steam is then used to power steam turbines, which in turn power the ship's screws and generators. The US Navy has steam plants, gas turbines, diesel and nuclear powered vessels.
Yes, the electric power grid could be powered by electric power generated through nuclear energy.
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.

Power turbines are driven by steam. Steam can be raised by thermal, nuclear or geothermal processes. Wind and water can also drive a generator. The auxiliaries for a power station (which I think is what this question is asking) are typically powered by step down transformers within the power station. In nuclear power stations there are often standby-critical supplies which are driven by gas turbines or diesel generators.
There are numerous sources of power for various lighthouses depending on their location and construction. Diesel powered generators.Photoelectric arrays storing energy in lead-acid accumulators.Electric cables from the power grid.etc.and combinations of the above,
Yes. Nuclear power plants and nuclear powered ships and submarines use controlled fission reactions.
Internal combustion gasoline or diesel engines power cars. Cars are also powered by electric motors.
Nuclear power provides about 19 percent of total electricity, but when you use electricity you are not aware where it has come from
