Introduction
Hydroelectric energy is a form of renewable energy that is generated by the kinetic energy of falling water. It is one of the oldest and most widely used forms of renewable energy, and it provides about 16% of the world's electricity. Hydroelectric energy is a sustainable and clean source of power that has many advantages over other forms of energy. In this article, we will discuss how hydroelectric energy is made, its advantages and disadvantages, and some recent facts about this form of renewable energy.How is Hydroelectric Energy Made?
Hydroelectric energy is made by harnessing the kinetic energy of falling water. The process involves the construction of a dam across a river, which creates a reservoir of water. When the water is released from the reservoir, it flows through turbines that are located at the base of the dam. The turbines are connected to generators, which convert the kinetic energy of the falling water into electrical energy. The electricity is then transmitted to the power grid, where it is distributed to homes and businesses. The amount of electricity that can be generated by a hydroelectric power plant depends on the height of the dam and the amount of water flowing through the turbines. The higher the dam, the greater the potential energy of the falling water, and the more electricity that can be generated. Similarly, the greater the flow of water through the turbines, the more electricity that can be generated. Hydroelectric power plants can be classified into two types: impoundment and run-of-river. Impoundment power plants use a dam to create a reservoir of water, which is used to generate electricity. Run-of-river power plants do not use a dam, but instead use the natural flow of the river to generate electricity.Advantages of Hydroelectric Energy
Hydroelectric energy has many advantages over other forms of energy. Some of the advantages include: 1. Renewable EnergyHydroelectric energy is a renewable source of energy that will not run out. As long as there is water flowing in rivers, hydroelectric energy can be generated. 2. Clean Energy
Hydroelectric energy is a clean source of energy that does not produce air pollution or greenhouse gas emissions. 3. Reliable Energy
Hydroelectric energy is a reliable source of energy that can be used to meet the base load demand for electricity. 4. Cost-Effective Energy
Hydroelectric energy is a cost-effective source of energy that has low operating costs.
Disadvantages of Hydroelectric Energy
Hydroelectric energy also has some disadvantages that should be considered. Some of the disadvantages include: 1. Environmental ImpactThe construction of dams and reservoirs can have a significant impact on the environment, including the displacement of wildlife and the destruction of habitats. 2. Limited Locations
Hydroelectric power plants can only be built in locations where there is a sufficient supply of water and a suitable site for a dam. 3. Capital Intensive
The construction of dams and hydroelectric power plants is capital intensive and requires a large upfront investment. 4. Risk of Drought
Hydroelectric power plants rely on a steady supply of water to generate electricity. In areas where there is a risk of drought, the supply of water may be limited, which can affect the amount of electricity that can be generated.
