OBJECTIVES

• Determine what causes hydroelectric power to

produce electricity

• Describe how a hydroelectric power plant produces

electricity

• List advantages and disadvantages of hydroelectric

power

WHERE DOES HYDROELECTRIC ENERGY COME FROM?

• “Hydro-” means water

• “-electric” means electricity

• Hydroelectric energy is electricity gained from

flowing water

HOW DOES WATER PRODUCE ELECTRICITY?

• Water is influenced by gravity

• That tendency can be used to turn a turbine

HOW HYDRO ELECTRIC WORKS

• Generally the hydro energy plants comprises the

generator ,turbine stator generator shaft and turbine

blades to generate electricity when the water flows

the turbine blades the turbine convert the energy it

generators into mechanical form and the generators

turn those mechanical energy into electricity , the

generator works on principles of magnetic , it

means that when you move a magnetic past a

conductor it cause the electric flow

THE TURBINE WORKS

HOW TO PRODUCE LARGE AMOUNT OF ELECTRICITY

• Governments construct dams across big rivers

so that they can harness the kinetic energy

release when this water passed through a

turbine they are able to produce the electricity

in a large scale

HYDROELECTRIC DAMS

• Three Gorges Dam in China is the largest

hydroelectric plant in the world

HYDROELECTRICITY FROM THE TIDES

• Ocean Tides can produce hydroelectricity

• Uses the motion and speed of the waves to power a

turbine

ADVANTAGES OF HYDROELECTRIC POWER

• Hydroelectric Power Stations can last for many

decades

• Hydroelectric energy does not pollute the

atmosphere

• Hydroelectric Dams can be used for other purposes

DISADVANTAGES OF HYDROELECTRIC POWER

• Dams are expensive to build and take a long time

to repay the investment

• If a dam is not built correctly, the dam could break

causing serious flooding and damage downriver

• Large dams can cause geological problems
