Hello Everyone,
Today we are going to talk about electricity.
Stop for a moment and look around.
You will surely see electricity in action.
From the cable charging your computer, to
the bulbs lighting up your room, to the kettle
that heated your hot chocolate: Electricity
is a key part of our lives.
However, it was only recently, with the invention
of the light bulb in 1870, that humans began
using Electricity for their benefit.
Electricity is nothing but ENERGY.
We eat FOOD every day and this gives us ENERGY-
Similarly, ELECTRICITY gives machines and
gadgets ENERGY.
And just, as our food comes from various sources,
similarly, electricity can come from many
different sources; some NON-RENEWABLE and
others RENEWABLE.
Non-Renewable sources are those which cannot
be replenished, that is made again in a short
period of time.
Some examples of Non-Renewable sources are:
Uranium
Coal
Natural gas and
Oil and petroleum products
On the other hand, Renewable sources can be
used over and over again to produce energy
without creating waste.
That makes these resources environmentally
friendly.
Some examples of Renewable sources include
Solar power
Water , also known as hydro power
Wind power
Geothermal power and
Biomass
I will talk more in detail about both these
sources in 2 other videos so let us focus
on another key topic: Conserving Electricity.
You've probably heard the grown-ups in your
house say "Turn off the light!"
Have you ever wondered why?
Electricity is there whenever we need it,
so it's easy to forget where it comes from,
or how much it costs.
Electricity is nothing but ENERGY but it isn't
FREE.
The grown-ups in your house pay for the all
the electricity you use.
So Wasting Energy is the same as Wasting Money
Wasting electricity isn't good for the environment
either.
Some of the electricity is generated using
Non-Renewable resources like coal and natural
gas that cannot be replaced - once we use
them up, they're gone forever.
Another problem is that some forms of energy
like nuclear power or coal can cause pollution.
So how you can help save Electricity?
Some basic things which can help save lot
of electricity are:-
Turn off light bulbs and other electronic
gadgets when you are not using them.
Use energy-smart light bulbs wherever possible.
Use Washing machine and dishwashers more effectively.
(For example use them only when there is a
full load.)
Also avoid using dryers.
Instead try to use the sun’s rays to dry
clothes.
Finally, I leave you with 3 facts about Electricity:
Thomas Edison owned the first power plant
ever!
The power plant opened in New York City in
1882.
The strength of an electric current is measured
in VOLTS and last but not least
Electricity travels at a speed of light that
is more than 186,000 miles per second.
