- 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 • Windfarms are areas where many large wind turbines have been grouped together to “harvest" the power of the wind.

- 12. Types of WindFarm 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.

- 18. Common Advantages of Offshore& Onshore Wind Farm No Pollution and Global Warming Effects Low Costs Big Industrial No Fuel
- 19. Limitation of Offshore WindFarm 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 OffshoreWind Farm Risks of increased turbidity, Negative impacts on seabirds through habitat change. Increased noise levels generated by wind farms,
- 21. Anticipated positive impactsof 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 windfarms are emerging as an alternative energy supplement, but its impacts on ecology should be thoroughly overcome before implementing.
