This document discusses the history and development of wind energy technology. It begins by introducing wind energy as a renewable source of power that can help reduce carbon emissions. It then provides a brief history of wind power usage dating back thousands of years. The document proceeds to explain the basic components and types of modern wind turbines, including horizontal and vertical axis designs. It also outlines some challenges with wind power, as well as new and developing technologies that could help advance the industry. The presentation concludes by noting the rapid growth of wind energy globally in recent decades and optimism for further expansion in the future.

2. INTRODUCTION
 Wind energy, as a clean and
renewable energy, is now
being widely developed to
reduce the production of
carbon dioxide from fossil
fuels and mitigate the energy
crisis. The urgent needs for
wind energy motivate larger
generators with lower cost,
lower weight, and higher
reliability and new
technologies to make it a
frontrunner.

3. HISTORY OF WIND USE
Man’s harnessing of the wind goes back thousands of
years
 Sail Boats
 Wind Mills
 Wind Turbines

4. HOW DOES IT WORK???
Wind turbines convert wind energy to electricity
for distribution. Conventional horizontal axis
turbines can be divided into three components:
 The rotor component
 The generator component
 The structural support component

5. TYPES OF WIND TURBINES
Wind turbines can rotate
about either a horizontal
or a vertical axis.
♣ Horizontal-axis wind
turbines (HAWT)
♣ Vertical-axis wind
turbines (VAWTs)

6. WIND TURBINE GENERATORS
WTG’s are of following
types:
 DC Generators
 AC Synchronous
Generators
They may be of:
1. Fixed Speed Type
2. Variable Speed Type

7. SPECIFIC WIND POWER PROBLEMS, ALLEGED
PROBLEMS AND OBJECTIONS
 Noise problems
 Power availability and transmission
problems
 Environmental problems
 Inequible spread of financial benefit
 Aesthetic problems
 Social disruption
 Other problems

8. ADVANCEMENTS IN WIND POWER: NEW
TECHNOLOGIES AND IDEAS
 Solar Wind
Power
 Wireless Energy
Transmission
 EWICON

9. NEW TECHNOLOGIES (CONTD.)
 T Boxes
 IMPLUX

10.  Power WINDows  Architectural Wind

11.  Honeywell Wind
Turbines
 Flying Wind Farms
 Smart Grid Integration
 Compressed-Air
Energy Storage –
CAES

12. USE OF HIGH TEMPERATURE SUPERCONDUCTIVITY
 HTS Transmission Lines
 HTS Generators

13. REVOLUTIONARY TURBINE DESIGNS

14. SCOPE OF WIND POWER IN INDIA

15. CONCLUSION
 The installed power in
wind energy has grown
rapidly in many years.
Today more than 45000
MW are installed
globally with recently an
annual market of 8000
MW. The expectations
for the future are also
very positive as many
countries have
progressive plans.
 Of course there are
problems associated
with wind farms
