HYDROELECTRIC POWER Meaning and
Definition
-
Hydroelectric power, also known as hydroelectricity, is a form of renewable energy generated from flowing or falling water. It is a clean and sustainable source of power that harnesses the kinetic energy of moving water to produce electricity.
The process of obtaining hydroelectric power involves the construction of dams, reservoirs, and power stations near rivers or water bodies. As water is released from the reservoir, gravity causes it to flow through turbines, which are large, rotating blades. The flowing water turns the turbines, driving the generator to produce electricity.
Hydroelectric power provides numerous benefits. First and foremost, it is a renewable energy source as water replenishes naturally through the water cycle. Additionally, it produces minimal greenhouse gas emissions, reducing its impact on climate change. It also helps to combat air pollution by replacing fossil fuel-based power plants. Hydroelectric power plants are highly efficient, making them capable of generating large amounts of electricity to meet energy demands.
The generated electricity can be used for various purposes, including industrial processes, residential and commercial use, and powering transportation systems. It provides reliable and consistent power, as water flow can be controlled and stored in reservoirs for future use during peak demand periods.
In summary, hydroelectric power is a clean and sustainable form of energy that harnesses the kinetic energy of flowing water to generate electricity. It offers numerous environmental benefits, including its renewable nature and minimal greenhouse gas emissions, while providing a reliable source of power for various applications.
Etymology of HYDROELECTRIC POWER
The word "hydroelectric" is derived from two components: "hydro" and "electric".
1. "Hydro" comes from the Greek word "hydor", meaning water. It refers to anything related to water or water-based activities.
2. "Electric" originates from the Greek word "elektron", which initially referred to amber's ability to attract lightweight objects when rubbed against wool. Eventually, it came to represent electricity in general.
Combined, the term "hydroelectric" indicates power generated from water or water-related sources to produce electricity.
