HYDROPOWER

WHAT IS HYDROPOWER
Hydropower is the electricity or power that is generated from the energy of moving water.
It is a renewable source of energy.
It is constantly being refilled by the water cycle, specifically precipitation.

TYPES OF HYDO POWER

USES OF HYDROPOWER
 The first and foremost use of hydropower is to generate electricity
 Hydropower also powers machines.
 Hydropower has been used for irrigation and operating mechanical devices (such as water mills, sawmills, and dock cranes) during ancient times
 Watermills produced flour from grain, sawed timber and stone, and pounded linen into paper. They also extracted metal from ores

HOW HYDROPOWER
WORKS
Hydro Dams and Power Plants
 When the dam gates are open, the water flows through a pipe called a penstock and pushes on the turbines, causing them to turn. They power a generator which produces the electricity.
 Spillway gates release extra water in rainfall. Dams expel water when needed for electricity production.

ADVANTAGES

DISADVANTAGES

 Hydropower is the least expensive method of generating electricity.
The flowing water is free and renewable by the water cycle.

 Hydropower may become more expensive in the future.
Licensing and assessing dams is a long and expensive process.

 It is readily available. It can be controlled easily.
 Hydropower can store energy. The water can be saved and managed
efficiently,
