2. Energy may be defined as the capacity to do
work.
 Energy is intimately related to power.
 Energy is the amount of force or power when
applied can move one object from one position to
another.
 Energy are broadly classifies into two main groups-
1)Non renewable energy source
2)Renewable energy source

3. Non-renewable energy source
A non-renewable energy resources are the type of
resources which once depleted cannot be replenished
in a short duration.
It cannot be used again and again.One day it will be
exhausted.
Non-renewable sources are not environmental
friendly and have serious affect on our health.

4. Non-renewable energy sources:
Coal
Natural gas
Oil
Nuclear energy

5. Advantage:
 Available in highly concentrated form.
 Easy to store and transport.
 Reliable supply and they have high energy density.
Disadvantage:
 Highly polluting.
 High running cost.
 A fossil fuel contribute to global warming.
 Its residual products are generally non-biodegradable.
 It produces greenhouse gases.
 Responsible for acid rain.

6. Renewable energy:
Renewable energy is energy which is inexhaustible;
generated from natural sources such as sun,wind,
rain,tides and can be replenished again and again
even
after its usage and consumption .
This can be renewed over relatively short period of
time.

7. The five major renewable energy sources
are-
1)Solar energy
2)Wind energy
3)Hydropower energy
4)Biomass energy
5)Geothermal energy

8. Advantage:
 Low pollution.
 Free of cost.
 Available in nature.
 A very large amount of energy could be generated
in this way.
Disadvantage:
 Usually produced in small quantities.
 Often very difficult to store.
 High cost of harvesting enery.

9. Why to conserve?
We have limited fuels available on earth.
Our demand for energy is increasing day by day.
It is possible that someday ,most of the fuels will be
exhausted and we will have to switch over to alternate
energy.
Once it is used,it cannot be formed again.As
Petroleum once used cannot be renewed again.

10. Energy efficiency:
About 82% of the commercial energy consumed in
the world comes from non-renewable energy
resource.
The remaining 18% comes from renewable energy
resource.
India now at 5th global position for overall installed
renewable energy capacity.

11. India would reach target of 175GW renewable
energy generation by 2022.
India to have 60% renewable energy by 2030,says
Power minister.
India is set to achieve 450 GW of renewable energy
installed capacity by 2030,the Ministry of New and
Renewable Energy said on 12 October 2021.
