Definition
Hydroelectric power is generated by converting the potential and kinetic energy of flowing or falling water into electricity using turbines and generators. It is one of the most widely used forms of renewable energy globally.
A dam is a barrier built across rivers or streams to control water flow and create reservoirs for storing water. Dams play a crucial role in hydroelectric power generation by regulating water release through turbines.
Reservoir: A reservoir is an artificial lake created by constructing a dam. It stores water that can be released through turbines to generate hydroelectric power.
Run-of-River: Run-of-river hydroelectric systems generate electricity by diverting a portion of flowing river water through turbines, without the need for large reservoirs or dams. This method minimizes environmental impact and maintains natural river flow.
