![Page 1: How is electricity produced through water?. Potential Energy of water - Gravitational Energy Potential Energy of water - Gravitational Energy Kinetic.](https://reader035.fdocuments.in/reader035/viewer/2022062409/5697bfa01a28abf838c9553b/html5/thumbnails/1.jpg)
How is electricity produced through water?
*Hydro-Power

*Energy Transfer
Potential Energy of water - Gravitational Energy
Kinetic Energy of Water- Motion Energy
Potential Energy of turbine –
Mechanical Energy
Released and become kinetic energy – Motion
energy
Turned to Electrical Energy through generator

*Transfusion of energy - Progress
Transferring step 1 :
*Water trapped stored great amount of potential energy – gravitational
* Gravitational energy – Energy stored in object’s height and weight
*Great amount of energy stored as the long trapping time of the water
Potential Energy of water - Gravitational Energy

*Transfusion of energy – Progress
Transferring step 2 :
*Water flush down
*Gravitational Energy
Kinetic Energy – Motion Energy
*Motion Energy – Stored in object movement
*Energy increase as the speed increased
Kinetic Energy of Water- Motion Energy

*Transfusion of energy – Progress
Transferring step 3 :
*Potential Energy in turbine is released by the water as it turned the turbine
*Mechanical Energy – Stored in object by tension
*Potential Energy – Mechanical Energy
Kinetic Energy – Motion Energy
*Motion energy of water increase release more mechanical energy stored in the turbine to motion energy
Potential Energy of turbine –
Mechanical Energy
Released and become kinetic energy – Motion
energy

*Transfusion of energy – Progress
Transferring step 4 :
*Turbine turned connect to electrical wire
*Motion Energy
Kinetic Energy – Electrical Energy
*Electrical Energy – Delivered by electrons, usually through wires
*Motion energy in turbine transfer to electrical energy through generator
Turned to Electrical Energy through generator

ELECTRICITY
IS PRODUCED
FOR US NOW!

*Transfusion of energy – Energy Loss
Energy loss:
*Not all energy is released
*Loss 1 – Encounter drag forces from penstock and pipe wall
*Loss 2 – Heat and sound generated when hitting the turbine
*Loss 3 – Water leave turbine still containing some motion energy

*Transfusion of energy – Energy Loss
Energy loss:
*Loss 4 – mechanical losses between the turbine and generator systems
*Loss 5 – losses from generator inefficiencies losses from transformer and other power conditioning inefficiencies

* The good impacts of hydroelectricity
*It is clean, it can reduce pollutions created.
*It produces cheap electricity
*It is producing electricity continuously
*It is much safer than nuclear energy

*The bad impacts of
hydroelectricity*The dams that were created to store the water energy is damaging the environment.
*The dams that need to be created to generate hydroelectricity is really expensive, the Hover Dam in USA costs 690 million dollars and the Three Gorges Dam in China costs 37 billion dollars.
*Structural failures of dams all over the world had caused million of deaths.
