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 waterProcessing 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].

Classification:

SMALL SCALE

• <40KW• Remote

houses

MEDIUM SCALE

• 40KW-1MW

• Village power/hybrid system

LARGE SCALE

• >1MW• Grid

connection

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]

Statistics:Total capacity : 76 GW *Installed capacity : 18.4 GWRemaining capacity : 57.6 GW (to be utilized)

* at an average height of 65m.

10

How can we utilize it…..?

11

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

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

13

Applications of SWT:Mounting of small wind turbines

on cell phone tower.Installation of SWT in boats.

14

SWT on cell phone towers[8]:1. Investment on separate tower is

eliminated.2. Can reduce diesel consumption

by 75%.

SWT installed in boats[8]:1. It will eliminate the carrying of

diesel.2. Helps them economically.

15

Wind – Solar Hybrid SystemsA 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 TechnologiesSaphonian Bladeless Wind

Turbines [10] : -Cp is greater than 59.3% - Efficiency is around 80% for the

same swept area.

17

New TechnologiesHighview’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%

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.
