Pros and Cons of Hydroelectric Energy

SHARE

There are a lot of hydroelectric energy facts and uses of hydroelectric energy today. Research shows that it is an ancient source of electricity and the most used source of renewable energy.

The advantages and disadvantages of hydroelectric energy happen to be the reason why so many nations across the world have opted for it.

In this post, you will explore more information about the pros and cons of hydroelectric energy. You will also get to know the advantages of electricity and the unknown hydroelectricity facts. Let’s get started here.

Pros of Hydroelectric Energy

  1. Renewable Energy Source

Earth water is used to generate electricity for consumption. The possibility of water to run out is not there. It is the reason why hydroelectric power is going to be there for long.

  1. Reliable Source of Energy

Hydropower plants have the capability of producing electricity for long with the minimum failure rate. The feature has made many countries to rely on it as the primary source of heat.

  1. Clean and Green Energy Source

Production of electricity from hydroelectric plants does not involve the use of chemicals. The adverse effects of hydroelectric power to the environment are quite minimal.

  1. Cost Effective

The hydropower cost is quite cost-effective, although the initial value for construction hydropower plants tends to be high. The amount of electricity does not fluctuate, and the maintenance costs are low.

  1. Safe Source of Energy

Hydroelectricity only uses water for the production of energy. It is the reasons why it is considered to be the most reliable when compared to fossil fuels.

  1. Creation of Job Opportunities

Hydropower plants create employment opportunities for people living in the area. It helps to eradicate unemployment issues in the country.

  1. Recreational Opportunities

The stored water in the hydropower plants can be used for irrigation purpose, especially drought. It can also be used for developing recreation centers like swimming pools, among others.

  1. Controlled Energy Production

Production of electricity can easily be controlled, especially when the energy requirement is low. The water will be disconnected from flowing to the dam for some time.

  1. Have Long Lifespan

Water is used in the production of electricity, and the chances of water getting depleted are almost zero. Hence the creation of hydropower is going to have the most extended lifespan as compared to other sources of energy.

  1. Flexible

Hydropower plants have variable sizes, and they can be built anywhere in the country. They can fit in any environment easily as compared to the tidal energy source.

Cons of Hydroelectric Energy

  1. Expensive to Build Hydropower Plants

Almost all energy plants are quite expensive to construct and develop. Hydropower plants are no exception. Significant investments are required to spearhead a large amount of energy production that can serve the whole country.

  1. Environmental Damage

Hydroelectric energy ecological impact is quite excellent, especially on marine life. Diverting the flow of water can make affect the natural habitat of fish and other aquatic animals. It leads to the extinction of marine creatures.

  1. The threat to Human Life

Dams meant for hydropower production are prone to the development of strong currents. These currents can lead to the occurrence of floods that can displace people living around the power plant.

  1. Drought

The existence of drought can affect the production of electricity. Power production is dependent on high falls of water in the dam. Low frequencies make turning of turbines a big issue hence low power generation.

  1. Earthquake

Construction of large dams interferes with the arrangement of land structure. These large dams can lead to shocks. The problem frequently happens in China and India.

  1. Greenhouse Effect

Production of electricity from hydropower plants result in the emission of methane and carbon gases. The buildup of these gases results in the greenhouse effect and global warming.

  1. Low Lifespan

The advancement in technology has led to the discovery of nuclear energy. More research and development is being undertaken. The invention will make the use of hydropower for the generation of electricity to drop in the future.

  1. Might Cause Conflict

Countries that border large water reservoir for power production are likely to experience conflict. The situation is expected to happen due to the interference of water flow as a result of the construction of dams.

  1. Specific Locality

Hydropower plants cannot be constructed in all regions. It is specially built in areas with high attitude and that locality that experience high waterfalls.

  1. Destruction of Fish Passage

Construction of dams affect the flow of water in the lakes, and this can affect the migration of the fishes. It will hurt the fishing industry in the country.
