Pro:
Makes barely any pollution compare to other ways of creating electricity
Hydroelectric power is one of the most responsive (easy to start and stop) of any electric power generating source.
The conversion of the forces of water to electric energy can be up to 90 percent efficient.
Hydroelectric power produces no chemical or waste heat pollution.
Hydroelectric power plants require little maintenance.
Reservoir lakes can be used for recreation, and can provide considerable flood protection to downstream areas.
Groundwater reserves are increased by recharging from reservoirs.
Plants usually have an expected life span two to three times longer than conventional thermal power plants.
Hydroelectric installations can be used to breed fish and other acquatic products.
Con:
Construction costs of large-scale hydroelectric projects are high.
Damming rivers causes changes in ecological cycles and surrounding landscapes; self-regulating ecosystems are changed into ones that must be managed.
Sedimentation can progressively curtail a dam's ability to store water and generate energy.
There are a limited number of feasible sites for large dams.
Damming can cause loss of land suitable for agriculture and recreation.
Drought can affect power production.
Dams are vulnerable to natural forces. There is a high direct Death Rate from the failure of dams.
River channels downstream from dams are more susceptible to erosion.
Hydro comes from the Greek word for water. Hydro-electricity, or hydro-power, is usually generated by turbines in a dam in a river. The dam means that a great body of water builds up in the river valley behind the dam. This is released through the turbines when electricity is needed.
Smaller than dams are barrages across the mouths of rivers which capture water from high tides and release it to generate electricity. Smaller still are turbines in river and tidal streams which do the same thing.
A. Advantages:
B. Disadvantages:
In brief:
Hydro was the first commercial source of power of any size. The uses were understood right away, but there certainly are drawbacks.
They destroy farmland and alter the course of rivers. They must also be located at the discretion of the plant rather than our choosing. Much of our power that we use today is not even used constructively. There is a large portion of our energy that is used in transporting it across the country. The major disadvantage I would put against this form of power would be the land and energy consumed in transporting the power away from the plants. Grid loss is a major issue for energy users.
It is a renewable energy source. Unlike fossil fuels which will eventually run out, hydro power plants do not use up the energy source. It is also not polluting to the environment. They output power at a relatively reliable rate (compared to solar or wind, especially). On the other hand, they drastically affect all ecosystems upstream of the dam, and are much more environmentally destructive than nuclear power plants.
Advantages
Disadvantages
The advantages of hydraulic power is that its good for the environment, it doesn't use up much energy and its harmless to animals and the planet.
Hydraulic power can be made very powerful (tons and tons of force), but it needs to be very large in size in order to do so
Pro's - Renewable, Can make large amounts of energy in a small space of time
Con's - Destroys habitats, Visual Pollution
Pros: Renewable, non-toxic, easy to produce Cons: Doesn't produce very much energy
The advantages counterbalance the disadvantages so there aren't disadvantages.

next question
Hydroelectric power stations certainly have their advantages and disadvantages, as do all forms of electrical generation. Probably the best solution is to use a combination of different means of producing electricity, with hydroelectric stations as part of the mix.
whatever you want the advantages to be.
Advantages Scenic scenery Foods Hydroelectric energy Disadvantages Flooding Pollution of rivers could lead to bad smells
One of the advantages of hydroelectric power is that it does not have a negative effect on the environment. Another advantage is that it is cheap.
One way is that it produces less CO2
One of the advantages of hydroelectric power is that it does not have a negative effect on the environment. Another advantage is that it is cheap.
There are many advantages and disadvantages to expert power. One being, the power gets to their head. While it can be good by they know what they are talking about.
Advantages: X-ray and Power. Disadvantages: Genetic mutations and Cancer.
