3. Wind Energy
• Harvesting wind power isn’t exactly a new
idea
– sailing ships,
– wind-mills,
– wind-pumps

4. Significance of Wind
Energy
Green Power
Sustainable
Affordable
Economic Development

5. Wind turbines
A wind turbine is a device that
converts kinetic energy from the
wind into electricity.

6. Wind turbines
• Horizontal turbine
components include:
A. blade or rotor,
B. a drive train
C. a tower
D. other equipment,

8. Types of Wind turbines
Horizontal-axis turbines Vertical-axis turbines

9. Windmills Vs Wind
Turbines
• Windmills generate mechanical
energy, but they do not generate
electricity.
• Modern wind turbines harness
wind's kinetic energy and
convert it into electricity.

10. Wind Farm
• Wind farms are areas where many
large wind turbines have been
grouped together to “harvest" the
power of the wind.

11. Wind Farm

12. Types of Wind Farm
Onshore Wind farm
Onshore wind refers to
turbines located on land
Offshore Wind farm
Offshore turbines are
located out at sea or in
freshwater.

13. Offshore Wind Farm
 Europe is the world leader in offshore
wind power.
 The first offshore wind farm (Vindeby)
being installed in Denmark in 1991.
 As of 2010, there are 39 offshore wind
farms in waters off Belgium, Denmark,
Finland, Germany, Ireland, the
Netherlands, Norway, Sweden and the
United Kingdom, with a combined
operating capacity of 2,396 MW.

14. Offshore Wind Farm
 As of 2017, The London Array in United
Kingdom is the largest offshore wind farm
in the world at 630 MW.

15. Types of offshore
wind turbines
1. Fixed foundation offshore wind
turbines

16. Types of offshore
wind turbines
2. Floating offshore wind turbines

17. Types of offshore
wind turbines
3. Vertical axis offshore wind turbines

18. Common Advantages of
Offshore & Onshore Wind Farm
No Pollution and Global Warming
Effects
Low Costs
Big Industrial
No Fuel

19. Limitation of Offshore
Wind Farm
 It’s very difficult to build secure structures in
water deeper than 60 m.
 Waves, hurricanes, can be detrimental to
infrastructure.
 Underwater cables are expensive and easily
broken.
 turbines within 26 miles of shore are unpopular
because of the fear that they will affect tourism or
property value.

20. Ecological Impacts of
Offshore Wind Farm
 Risks of increased turbidity,
 Negative impacts on seabirds through
habitat change.
 Increased noise levels generated by wind
farms,

21. Anticipated positive impacts of
Offshore Wind Farm
 The protection against fishing activities
inside the wind.
 Combined with a possible reef effect,
 Fouling organisms colonising artificial
hard substrata.

22. Conclusion
• Since wind farms are emerging as an
alternative energy supplement,
but its impacts on ecology should
be thoroughly overcome before
implementing.
