Hydroelectric power

Definition

Hydroelectric power is a renewable energy source that generates electricity by harnessing the energy of flowing water, typically from rivers or dams. This process involves using the gravitational force of falling or flowing water to turn turbines, which then convert mechanical energy into electrical energy. Hydroelectric power is significant because it provides a clean and sustainable way to produce electricity, reducing reliance on fossil fuels and lowering greenhouse gas emissions.

5 Must Know Facts For Your Next Test

1. Hydroelectric power accounts for about 16% of global electricity production, making it one of the largest sources of renewable energy worldwide.
2. The efficiency of hydroelectric plants can be as high as 90%, meaning that a large portion of the energy in flowing water is converted into electricity.
3. While hydroelectric power is renewable, its environmental impact can include habitat alteration for aquatic life and changes in local ecosystems due to dam construction.
4. Pumped storage hydroelectricity is a method used to store energy by moving water between reservoirs at different elevations during low demand times and releasing it during peak demand.
5. Countries like China, Brazil, and Canada lead in hydroelectric power generation, utilizing large-scale dams and river systems to produce significant amounts of electricity.
