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.
A conventional power plant is usually either a gas or coal fired plant. I can, on occasion, include nuclear power plants but it depends on context. It will never, however, include 'green' power plants such as hydro-electric dams, tidal barriers, wind farms, etc.
Tidal waves are not used to generate electricity. A tidal wave is a huge wave, rather like a tsunami, that occurs very infrequently, and without warning.Tides are harnessed to produce electricity, and also waves are used, but not tidal waves.
Water energy (kinetic energy) to mechanical energy to electrical energy!
It can be relied on and also it produces electricity reliably. tidal energy is a renewable energy, when compared to solar and wind energy it is more efficient source.
Hydroelectric plants use energy from moving water

Hydroelectric, tidal and wind are all renewable sources of electrical enengy.
Electricity is mainly generated by coal/oil-fired plants, nucealr plants, hydroelectric dams, wind farms and tidal power generators.Some areas have few or none of some forms while focusing or relying on others.

The benefits of Tidal power begins with it as a renewable resource. Gravitational fields and natural earth and astronomical occurrences will continue to create tides Since it is not dependent on fossil fuels, Tidal power is green and does not appear to cause damage to the environment. Tides are also highly predictable. On the negative side, no studies have been completed to definitively prove that Tidal power is not environmentally damaging. Plants will need to be constructed close to land and it is expensive. Hydroelectric power, like Tidal power is renewable, flexible and safe. However, it poses risks to the environment such as damage to fish. It is also expensive and could be adversely affected by environmental factors such as drought. There are also a limited number of needed reservoirs available.
Tidal power stations require specialized technology to capture energy from changing tides, which is still in the early stages of development and more expensive to build and maintain compared to traditional hydroelectric power stations. Additionally, tidal power stations face more technical challenges due to the harsh marine environment, increasing their construction and operation costs.
