Hydro Power

The sum total of all the external conditions affects the environment and all the living beings which exist in it. If the environment is affected by some means then all the animals, plants and human beings are also affected by the stimuli which occur in their behavior and survival. This change occurs by population explosion or distinction, depletion of natural resources and pollution. So anything that affects ecosystem is indeed harmful and needs to be eradicated. Similarly, hydropower is not the biggest source of energy on earth although it has a very less cost because it has many disadvantages.

Disadvantages of hydroelectric power

There are many disadvantages of hydroelectric power due to which it is not used on a very large scale all around the globe. Before employing something on an industrial level, you should consider pros and cons of hydropower. So the disadvantages are:

Emission of methane and carbon dioxide

The reservoir of water for hydroelectric power releases a large amount of carbon dioxide and methane. The area around the dam is filled with water. The plants and trees in them start rotting and decompose by other method without the use of oxygen. So this type of decomposition dumps a great amount of methane and carbon dioxide which increase pollution.

Disturbance of habitat

The formation of large and huge dams destroys the living beings around them. Local life is disturbed as human can’t live in such a flooded area and plants are destroyed. People living nearby have to relocate.

Installation costs

Although the effective cost is zero but the manufacturing and building a dam and installation of the turbines is very costly due to which many countries do not employ this alternative source of energy. If the initial cost had been less; then it would have used more commonly. Its construction requires a lot of human capital and labor. Its maintenance is also very costly.

Limited use

As the hydroelectric power is produced by the water which depend on the yearly rain falls so only those areas can use this method which receives a good amount of rainfall water because this method needs a huge reservoir of water.

Divert natural waterway

Dams and rivers collect water for the production of electricity which alters the natural system of water flow thus depriving houses of the water they need.

Effects on agriculture

Making dams on rivers affect the amount, quality and temperature of water that flow in streams which has drastic effects on agriculture and drinking water.

Fish killing

The water while flowing through the dam collects nitrogen which can damage and also kills fish. They can also damage the reproduction of fishes thus eliminating the whole species of fishes.

Disputes between people

Changing the river pathway and shortage of water can cause serious disputes between people.

Breaking of dams

Many dams which were built for industrial use or for mills are not now used and occupying a great space but they can’t be broken or removed as it would cause serious flooding. This would not only affect the humans but also many buildings and property.

Deposition of silt

So the research is going on decrease its disadvantages and to make it happen on a large scale.

So hydropower is sustainable and long-lasting source of energy. It produces a great amount of electricity. Dams can also be used for other purposes like fishing and sports. All these advantages show the importance of hydropower electricity which gives us a solution for the problems of this boom and gloom economy.
