Presentation Transcript

  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.com http://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.aspx?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://news.softpedia.com/ https://sites.google.com/site/montvillewind/pictures/birds-wildlife http://irjci.blogspot.com/

  16. Wind turbine designs are evolving http://www.popularmechanics.com/science/energy/solar-wind/4324331
