2. Abstract:
In this presentation we will be
presenting the details of utilization of
wind energy and its overview. This
presentation highlights: how the wind
energy is being utilized, the present
state of usage of wind energy, how
can we utilize more, new
technologies…etc.

3. Introduction:
Wind energy is a form of solar energy
produced by uneven heating of the
Earth's surface.
 Why…?
- renewable energy.
- clean & cheap energy.
- long life.

4. In ancient times…..
Pumping of water
 Processing of grains

Horizontal Axis, Chinese windmill
for pumping water. Still used in
some parts of china today [1]
The windmills that were used for
processing of grins [2].

6. Present scenario :

Total installed capacity has reached
to 282.43 GW in which about
44.71GW is installed in the year
2012. [3]

In India, the total installed capacity
has reached to 18.4GW out of which
2.3GW is added in 2012. [4]

11. Ways to utilize more…..
Small Wind Turbines (SWT).
 Wind - Solar Hybrid systems.
 Off-shore wind turbines.

11

12. Small Wind Turbines (SWT):
Generally a wind turbine which is producing a
power in the range of 50W-40kW is called as small
scale wind turbines.
 WISE estimates India’s micro-generation potential
at about 83 GW.[7]
 Can be used for house hold & equipments such as
parking meters, traffic warning signs, street lighting
etc.
 IEC 61400-12

12

13. Applications of SWT:
Mounting of small wind turbines on
cell phone tower.
 Installation of SWT in boats.

13

14. SWT on cell phone towers[8]:
1. Investment on separate tower is
eliminated.
2. Can reduce diesel consumption by
75%.


2.
SWT installed in boats[8]:
It will eliminate the carrying of diesel.
Helps them economically.

15. Wind – Solar Hybrid Systems
A cumulative capacity of 1647 kW of
wind-solar hybrid systems has been
installed so far in India.[9]
 Can be used where there is both solar
and wind rate are good.


16. New Technologies

Saphonian Bladeless Wind Turbines
[10] :
-Cp is greater than 59.3%
- Efficiency is around 80% for the
same swept area.
16

17. New Technologies

Highview’s LN₂ power storage [11] :
-It will make use of energy
created during night time.
-The company claims that
their system’s efficiency
is as high as 70%
17

18. Conclusions :
We can make more wind energy
utilization by using SWT.
 Efficiency of wind turbines can be
increased by using bladeless wind
turbines.
 By making use of LN2 we can reduce the
waste of energy & can utilize more wind
power.
 We can increase the interest in wind
energy sector by introducing some
mandatory subsidies/policies in Union
Budget.
