hydro power is practically always constant wind power might not be there at all sometimes and it could be a load as opposed to a source.
Hydro turbines can be of far higher capacity compared to wind
probably
Both use the flow of water generate electricity. Hydroelectric uses the flow of water from a high point to a low point. (A damn). Tidal power uses the flow of ocean tides in and out.
Along rivers or streams, at the foot of hills and mountains with ponds or lakes, and at the mouths of bays and inlets where there are tides. Hydroelectric plants operate on the basis of gravity moving water downward. So the requirement for hydroelectric power is water and a difference in height, altitude or depth. Most Hydroelectric plants are located on rivers and used dams to provide the difference in height. In some cases, hydro plants have been built at the foots of hills or mountains that had lakes on them at higher levels. If the difference in altitude is sufficient, a small flow and a small power plant can produce an impressive amount of power. It is possible to get hydroelectric power from the movement of water without a dam, and this is done in rivers with sufficient current, but where damming the river would be too destructive to the land or things on the land. It is also done in places with tidal flows that are sufficiently energetic. Micro-hydroelectric sites can even be small streams, if the water flow is sufficiently reliable.
No nuclear ones, apart from Bataan which has never operated
when water fiows from water resource then potential energy converts into kinetic energy. due to this water rotates to the turbines and conversion of kinetic energy into mechanical takes place . the shaft of turbine is connected to generator and in turbine due to rotation magnetic flux takesplace and electricity is produced.

No. A hydroelectric plant uses falling water to turn water turbines attached to electric generators.
All use generators to produce electrical current
Turbines. These are then used to spin magnets next to wires. This generates electricity.

Hydroelectric power plants convert GPE into electric energy. When the water flows from the higher point to the lower point, hydroelectric turbines convert the energy of the flowing water into energy.
With a pumping station, they use pumps to perform a function with a liquid. This might include moving drinkable water or sewage up hill, for example. A hydroelectric plant uses water flowing downwards to turn turbines to produce electricity. Some hydroelectric plants have pumping stations that move water up hill into holding facilities from which it is released to turn additional turbines during periods of high demand for electricity.
Hydroelectric plants use the running water by a turbine with blades on it, and when the water flows through these turbines they rotate,. in turn rotating the alternators that make the electricity which is sent from the power-station via the wires to houses, businesses etc that need the electricity.
Mavel is a Czech - American company that is one of the premier international engineering and manufacturing companies that provides hydro turbines for small hydroelectric power plants worldwide.
They are usually located near natural fast flowing rivers, like Niagara Falls, or man made dams, like the Hoover Dam in the US, or Three Gorges Dam in China. But one thing they have in common is that hydroelectric plants need water to turn turbines to generate electricity.
Hydroelectric plants use energy from moving water
Light energy is produced by spinning turbines with steam in a power plant to turn a solenoid in a magnetic field to induce a current. The source of energy to turn water to steam is what makes a plant "green" or not. There are coal plants, natural gas plants, and nuclear plants. Some energy is also produced from hydroelectric dams, where rivers spin turbines instead.
