1. Introduction to Wind and Solar Power Kenneth M. Klemow, Ph.D. Wilkes University

2. What is wind power? Conversion of wind energy to useful form ◦ Mechanical energy ◦ Transportation ◦ Electricity http://www.makeenergynow.comhttp://apps.carleton.edu/

3. Why does wind blow? Uneven heating of earth’s atmosphere Large-scale cells Air pressure differences

4. Where is wind available?

5. Modern wind power uses turbines in arrays called windfarms http://inhabitat.com/

6. Wind turbines are evolving http://electrical-engineering-portal.com/ready-for-wind-power-its-time

7. Wind turbine nacelle

8. Connecting to grid

9. Global windpower capacity

10. Global wind as of 2013 http://www.renewableenergyworld.com/rea/news/article/2014/04/global-wind-market-is-just-fine-thank-you

11. Wind installation U.S.

12. Wind Power in PA Currently have 25 windfarms ◦ 720 turbines ◦ Total capacity – 1340 MW ◦ Enough to power 390,000 homes ◦ 1.5% all electricity Future capacity ◦ 3300-4000 MW ◦ Can power 1.17 million homes ◦ Meet 6.5% state’s electricity http://www.awea.org/Resources/state.asp x?ItemNumber=5188

13. Wind costs have declined

14. Benefits of wind power No emissions of carbon into atmosphere No radioactive waste Sustainable Energy is free – only cost is construction of windfarm and some maintenance

15. Concerns about wind energy Intermittent source of power Habitat fragmentation Bird and bat mortality Aesthetic concerns Fires Ice throw Wind turbine syndrome http://irjci.blogspot.com/ https://sites.google.com/site/montvill ewind/pictures/birds-wildlife http://news.softpedia.com/
