This document discusses renewable and non-renewable energy sources, with a focus on wind energy. It classifies energy sources as either conventional or non-conventional, and renewable or non-renewable. Renewable sources like wind are continually replenished by nature and have advantages of being non-exhaustible, while non-renewable sources like fossil fuels are finite. The document then describes how wind turbines work to harness wind energy and generate electricity, noting their advantages of being free and clean but also their disadvantages of having low energy density and variable output depending on wind conditions.

1. Renewable and non
renewable sources of energy
and wind energy

2. INTRODUCTION
• Energy exists in the earth or comes from
the outer space
• Capital Energy-The energy existing in the
earth
• Celestial Energy-The energy which comes
from the outer space

3. Classification Of Energy Sources
Based on availability and usage with
respect to time
1. Conventional energy sources
2. Non conventional energy sources
Based on the possibility of renewability
1. Renewable energy sources
2. Non renewable energy sources

4. Renewable Energy Sources
• These are continuously restored by
nature
• They are also called as inexhaustible
sources of energy

5. Advantages Of Renewable Energy
Sources
• Non-exhaustible
• Can deliver the energy required for a
specific task
• Can be built on or close to the site where
energy is required
• Reduce the cost of operation as the energy
resources are natural

6. The Disadvantages of
Renewable Energy
 It is difficult to generate the quantities of
electricity that are as large as those
produced by traditional fossil fuel
generators.
 Renewable energy often relies on the
weather for its source of power.
 Hydro generators need rain to fill dams to
supply flowing water.

7. Non Renewable Energy
Sources
• These occur once in nature and on
usage, they practically cease to form
under new geological conditions

8.  Non-renewable energy is
the more traditional source
of energy and is most
commonly known as fossil
fuels.
 Non-renewable sources of
energy are much cheaper
than renewable sources but
are harmful to the
environment.

9. Advantages of Non Renewable
Non-renewable energy sources cannot be
replenished in a short period
Abundant and affordable
Cost effective and easier to produce and
use
Reliable supply
Available in highly concentrated form

10. Disadvantages of Non Renewable
 Once sources of non-renewable energies are
gone they can’t be replaced or revitalized
 The mining of non-renewable energy and
the by-products they leave behind causes
damage to the environment
 The burning of fossil fuels continues to rise
producing high levels of CO2 which is a
major cause of global warming.

12. Wind Power

13. Winds are
caused by
uneven heating
of atmosphere
by the sun .
hence it is an
indirect form of
solar energy.

16. Working of wind power plant
Wind turbines harness the wind energy to
generate electricity .Here ,in short ,is how
they do.
Wind makes blade turn
Blade turn a shaft
Gearbox connected to the shaft increases
rotational speed

19. Advantages of wind power plant
Energy for free of cost
Produces electricity throughout the day
Pollution free and clean
Vast wind energy is available
Can supply the power to remote areas

20. Disadvantages of wind
power plant
Low energy density
Irregular, unstudy wind energy
Variable speed and wind direction
Can be located only in vast open areas
Complex design
