Hydropower Energy has many Advantages and Disadvantages
In a sentence, hydropower energy is a renewable energy type produced by moving water. In old hydro power technology, it was necessary turbines turn so that the wheat cloud flour. Therefore the flow of water was a necessary. With evolution of technology, people use the water mill for hydroelectric energy. Its mean hydropower plants (HES) convert the power of the running water to electricity.
Flow or decline rate of the energy determine the energy in running water. Running water has a big kinetic energy. For example; water flowing in a large river carries a large amount of energy.
Advantages of the hydroelectric energy
Hydroelectric is Renewable Energy Source
The Hydropower operate with water that recycled to the ground during the water cycle process. Due to environmental and weather conditions, it is clear that water is gradually depleted. Besides, countries with an enormous source of water make hydroelectric energy a reliable source of energy. For example, China has the highest energy source through its hydroelectric power plant.
Green and Clear Energy
Unlike fossil fuel, nuclear and biomass energy sources, there are no waste materials in hydroelectric energy. Emissions and radiation aren’t harmful to the environment and people. Therefore, the renewable energy source is clear.
Hydroelectric Energy is a Reliable Energy Source
Hydroelectric energy is a reliable source of energy. China, India, Colombia, America and Canada has been the largest energy source to many countries. Hydropower plant has costly. Therefore, only developed countries use the hydropower energy. Moreover, the construction of dams is long-lived, so it will be a reliable source of hydroelectric energy.
Flexible and Energy Saving
Corporate companies and firms can easily control to energy. Therefore, if the required energy is less, the water flow in the dam is also reduced. Also, when the required energy is large, the water flow is maximized. Thus, more energy saving can be made for future use.
Cheap Production Cost
Dams are used for long-term. Therefore, the energy supply is also long-term.
Disadvantages of the Hydroelectric Energy
The many variety of plants and animals in the hydroelectric area, are damaged or destroyed. Due to hydropower plants, agricultural areas, forest areas, historical and cultural assets in this region are being flooded. Everything, including soil structure, vegetation, animal presence and bacterial system, is disturbed.
Effects on life in water
Establish of the large dam reservoirs or water dams interferes with the status of the aquatic fish species. Also, the river affects the fish by the discharge of water from the dam. Therefore, dams affect the fish habitats. Besides, the harmful river destroys the natural habitat of the fish, prevents the passage of the river. Also, it leads to a decrease in the number of migratory fish species and even extinction.
The water flowing from the dam creates a flood that affects the living or living organisms on the rivers. Decreasing or increasing water causes some plant species to disappear. However, some animals come from their habitats. Hydroelectric energy not only affects wetlands, but also displaces people residing near the dam. Many people are forced to move.
High cost of hydroelectric power plants
The creation of hydroelectric power plants and dams requires a high budget. While hydroelectric energy is a cheap cost, the construction of a dam will cost about $ 20 billion and it takes many years to finish.
Hydroelectric power depends on the presence of water but the amount of water supply will be limited when drought arrives. Also, reduction of water flow will affect the high price of electricity consumption. Therefore it cause limited use of electricity.
The climate of the region they are changing is changing, the climate is getting warmer. A significant amount of moisture is beginning to be seen. This causes changes in plant and animal diversity. The water temperature is changing. Because of the water attitude, the river’s ecosystem is deteriorating.
