the shaft inside the wheel turns be cause of the power generated by the rotation of the wheel.

Hydropower transform potential energy in water (height) and create electricity using dynamo. The dynamo is powered by hydropower. Simple mechanical design to use hydropower such as Rice mill using water flow and weight to make mechanical motion or Ram pump using the velocity of the stream make pumping of water to higher head.
Not directly, but fire can be used to help make electricity, for example fire can be used to boil water and make steam, steam can be used to power generators which in turn make electricity.
No, pure water does not conduct electricity. However, adding an electrolyte, preferably a salt, will release ions into the solution that make it electrically conductive.
The Sun heats and evaporates water. Some of this water falls as rain and is collected behind dams. An amount of this water is released through passages in the dam and travels downhill and gains kinetic energy. The water then passes through a device such as a turbine which spins. Energy is extracted from this spinning and is used to make machines work, usually by generating electricity. Sometimes the energy is used directly as in a water wheel to run machines. So your answer is solar power, condensation to make rain, construction to build dams, engineering to develop turbines and water wheels, electrical engineering to transport electricity, and science to make everything work at the usage site.

Water?
In hydro power the water from a dam is channeled through narrow down facing tunnels where it spins turbine wheels. These wheels axles are connected to electrical generators which make electricity.
Water at a height, pipework and a hydroelectric generator make electricity.
Get some water
The way a reactor works is rods of a radioactive material(say, uranium),are put into a bath of water, the heat from the radioactivity causes the water to vaporize. The steam then runes through wheels, the steam pushes the wheels and the wheels turning is used to generate electricity. But the heat is caused by radiation.
Usually the water will turn some wheels or turbine; this will then turn a generator, which generates the electricity.
Fruits generate electricity through a process called oxidation-reduction reactions. These reactions involve the flow of electrons from the fruit's electrolytes, such as citric acid or potassium ions, to metal electrodes. The movement of electrons creates an electrical current that can be harnessed for various applications.
Water mills were used to harness the energy of water to turn water wheels which would then turn huge stones that would grind wheat to make flour, corn to make corn meal and other grains into staples.

Water is a poor conductor of electricity. However, the presence of ions in water make the solution a good conductor of electricity.
