What Exactly is Hydroelectric Energy?


hydroelectric energy

Hydroelectric energy can be considered as one of the most prominent forms of energy that you can find out there in the world. It is true that solar energy and wind energy are some of the most popular renewable sources of energy that you can find out there in the world.

However, hydroelectric energy is catching up at a rapid pace. Therefore, it is extremely important to understand what hydroelectric power is and how power is being generated with it.

Back in the day, people constructed reservoirs, so that they can keep rain water gathered. Then they channeled the rainwater through a pipe to a turbine. The spinning blades of the turbine where then connected to a shaft.

This shaft was directly connected to a generator, which was able to produce energy. Due to this reason, hydroelectric energy can be considered as one of the simplest forms of energy that you can find out there in the world as well.

The technology behind hydroelectric energy has developed significantly throughout the past few decades. As a result, it has become an efficient method to generate energy as well. As of now, water is being collected mostly from the rivers and waterfalls.

When energy is being generated from water and transformed to electricity, it becomes hydroelectric power. According to the hydroelectric energy definition, this energy is mainly produced due to the potential that water has. Hence, it can be considered as a completely natural and a renewable source of energy available out there for you to consider as well.

In today’s world, massive dams are created with the objective of generating hydroelectric power in large scale. With that, they have been able to ensure a constant flow of water.

As a result, the turbines can also be moved constantly. The rotating turbines will then give life to kinetic energy, which causes the magnets located inside the generator to rotate. As a result, hydroelectric energy will be created.

Once electricity is generated, water will exist the turbine and return back to the stream, which is located under the dam. Therefore, moving water has been used as the resource in order to generate electricity. It has got the ability to lighten towns, cities and even entire countries.

With that in mind, it is also worthy to take a look at the hydroelectric pros and cons. Then you will be able to get a better understanding on where it stands in the list of energy sources.

It is true that the production of hydroelectric energy is not in a position to give life to any greenhouse gases. However, development of massive dams across the rivers can give life to a large number of social and environmental effects.

What are the pros of hydroelectric energy?

  • It is a renewable source of energy

When you take a look at the hydroelectric energy uses today, you will notice how it can provide an excellent assistance to the people with making their lives easy. It is one of the most effective renewable sources of energy available out there.

Water that is naturally generated in earth and obtained from rainfall are being used to make hydroelectric energy. Therefore, you will be able to have unlimited amounts of hydroelectric as well. In other words, we don’t need to worry about the scarcity of hydroelectric power.

  • It is a clean source of energy

As mentioned earlier, hydroelectric can also be considered as a clean source of energy that is available out there in the world. It is clean and green. Therefore, you don’t need to keep any doubts or second thoughts in mind when you are using hydroelectric.

When you are generating power out of hydroelectric, you are not contaminating anything. In addition to that, no greenhouse or toxic gases will be produced as well.

  • It is cost competitive

It has also been identified that hydroelectric energy is one of the most affordable forms of energy available out there. Water is an infinite resource. It is not affected by any factor. Therefore, it has been possible for the people to generate hydroelectric energy, while keeping the overall expenses low as much as possible.

On the other hand, the process used to generate electricity out of hydroelectric can easily be enhanced to match with the technological advancements that can be found out there in the world.

What are the cons of hydroelectric energy?

There are some cons associated with hydroelectric as well. Here are some of them.

  • Damage caused to the environment

Hydroelectric energy disadvantages include the damage caused to the environment. In other words, the construction of large scale dams are in a position to create a major negative impact on the entire river ecosystem, as well as the environment surrounding it. On the other hand, the number of fish deaths taking place will be enhanced due to the damage caused to the environment.

  • High upfront expenses

Even though it is possible to generate hydroelectric energy at a cheaper rate, there are upfront expenses associated with the process. You need to be mindful about these as well. It costs a considerable amount of money to develop a hydroelectric energy plant.

During the construction activities, people will come across a large number of logistical challenges as well. On the other hand, the maintenance of hydroelectric energy plants can also cost a lot of money.

  • It may cause conflicts

Some people believe that hydroelectric may cause conflicts to take place. For example, some of the countries will block rivers and create dams for the generation of hydroelectric power. This may create a major impact on the natural flow of water that another country is receiving. As a result, conflicts may arise.

Now you have a clear understanding about hydroelectric energy. With that in mind, you can determine if this is the best source of alternative energy available out there for the people in today’s world.
