4. Heat energy
It is the energy which is produced
by burning of fuels such as coal,
LPG, CNG, petrol, diesel, wood,
kerosene etc.
In our homes, we use heat energy to
cook food.
5. Light energy
Light energy helps us to see things around us.
Sun is the main source of light energy on the Earth.
Electric bulb, lamp, tubelight, and candle are some
other sources of light energy.
6. Mechanical energy
Energy that an object has because of its position
(potential energy) or its movement (kinetic energy) is
called mechanical energy.
The water stored behind a dam has potential energy,
which gets converted to kinetic energy as the water
falls from a height.
7. Electrical energy
Electrical energy is generated at power stations and
supplied to our homes.
It is used for running appliances such as electric bulb,
television, computer, washing machine etc.
8. Wind energy
Power of the
moving air
(wind) is utilized
with the help of
windmills to
generate
electrical
energy.
10. Solar energy
The energy that we
get from the Sun is
called solar
energy.
It is used to
provide heat, light,
hot water, and
electricity.
11. Geothermal energy
The energy that
we get from the
heat of the earth
is called
geothermal
energy.
It is used to
generate
electricity.
12. Renewable Energy
Energy that can be
renewed or replenished
over a period of time is
called renewable energy.
Example- Solar energy,
wind energy, and
geothermal energy.
13. Non-renewable Energy
Energy that cannot be renewed or replenished over a
period of time is called non-renewable energy.
Example- energy obtained from fossil fuels such as
coal and petroleum is non-renewable energy.
