Distribution of Electricity

In distribution substation,power is step-down(with transformer) to 220/440 KVA for single phase/three phase respectively.
From distribution substation,power is supplied to feeders. From feeders,power is supplied to distributers.
Distributer's distribute the power supply to consumer's.
No. of units consumed by the consumer is termed as KWH (Kilo-Watt per Hour).
There are loses in transmission of electricity which can be removed with lamination.

Transmission of Electricity-I

Electricity is generated in substation,but transmission is done in different manner.
Electricity is generated at 11kVA,it is step-up to 220KVA with help of transformer.
Primary transmission line transmit power to transmission substation,here power is step-down to 22KVA.
Secondary transmission line transmit the power to secondary transmission substation,here power is step-down to 11KVA.
Now,power is transmit to distribution substation (220V/440V).

Alternative method of generating Electricity

In the growing needs of human being,there occurs the shortage of electricity.It is estimated that after some years there will be no electricity available for our future generation,therefore alternative methods have to be developed in order to get continuous supply of electricity.
There are many methods:-
1.Hydro power generation
2.Thermal power generation
3.Nuclear power generation
4.Tidal power generation
5.Magneto-Hydro dynamic generator

4.Do not live in those places which are prone to disaster.
5.Living place should be easily accesible to hospital

Disaster cause to Earth

Earth sufer a lot because of human beings.
Green house effect,ozone layer depletion,deforestation etc. for all these problems humans are the main culprit.
Industrial waste,human waste etc. all the waste we dispose off into the river,which makes it poisonous.This causes danger to aquatic life.
Land pollution cause land degradation.
Air pollution cause air degradation means it changes the configuration of air particles.
So,reduce pollution to Earth

Pollution leading cause of bad Health

There is a tremendous growth in our population during some years.Due to this,demands of human beings(such as food,clothes & house)also increases day by day,causes deforestation & degradation of land.
Therefore,for all the natural calamities,human are responsible.But still we don't accept our mistake & keeps on repeating the same mistake.
Why we are doing this,do anyone have the idea?
Do anyone realizes what is the future consequenses of this?
