How water produce electricity
                     HOW WATER PRODUCE 
ELECTRICITY?
Introduction
Renewable energy and 
renewable energy sources are 
very important in the current 
situation of world.
Water is one of the renewable 
energy sources.
It is efficient and wise to use 
water for electricity generation.
 Electricity is generated at 
Hydroelectric power stations. The new economy
Hydroelectric power stations
Different methods are used for 
electricity generation.
1. Conventional method 
2. Pumped- storage method
3. Run – of – the river
4. Tide
5. Underground
Conventional method
Hydroelectric power station is consist of –
1.Reservoir – 
• A basic part of any hydroelectric power station.
• Reservoirs can be natural or artificial.
•  Water in the reservoir is in the form of potential 
energy.
Conventional method
2.Turbines– 
• There are three main turbines used for converting 
potential energy into Kinetic energy.
• Turbines are a vital part of any hydroelectricity 
power generation method.
1.Impulse turbine
2. Reaction turbine
3. Gravity turbine

Conventional method
How Turbine works– 
• The penstock which is a large pipe delivers the 
water from the dam or reservoir to the turbine.
• The turbine rotates and converts potential energy 
into kinetic energy. 
• The turbine is connected to the generator.
Conventional method
3.Generator–
• The generator is connected to the turbines.
• When the turbine rotates, produce kinetic energy.
• This Kinetic energy is converted to the electric 
energy by generators.
Electricity generation using 
Conventional method 
Other methods- 
• Turbine and Generator is a vital part of any 
method.
• How water delivers to the turbine decides the 
method.
• This Kinetic energy is converted to the electric 
energy by generators.
1. Pumped- storage method- uses reservoirs at 
different elevation
2. Run – of – the river- Upstream water is used.
3. Tide- Ocean water rise and fall used.
4. Underground- water delivers from Waterfall.
