Aims of this Workshop
PEDAGOGY• Determine the ways in which wind energy can be used to
teach physical science content, the engineering design process and inquiry skills
• Develop competency in hands-on, inquiry demonstrations and lab experiences about wind energy for the classroom
SCIENCE CONTENT• Differentiate between renewable and nonrenewable energy
sources • Explain the properties of fluids, like water an air, and how
these characteristics, combined with the energy of the sun, create wind
• Investigate the force of wind and determine the impact of a variety of factors on wind power
• Explore the components and design considerations of wind turbines
• Create an ideal blade design and analyze the efficiency of wind turbines using this design

What is Energy?
• Energy makes change possible. We use energy for everything we do.
• Heat, light, motion, electrical, chemical, nuclear, gravitational
• How would you classify the forms listed above?

What is Wind??
• 1 to 2% of the sun’s radiation turns into wind energy when it arrives on Earth
• This is 100 times all of the energy consumed on the planet!!

Nature of wind
• Wind is affected by many climatic and geographic factors• Wind is intermittent
• Win occurs both on land and at sea
• Wind speed is affected by topography and elevation
• Landforms affect the speed, frequency and turbulence of wind
• A minimum of 3 m/s is needed to drive a wind turbine and generate electricity
• A 10% increase in wind speed will lead to ~30% increase in power output from a wind turbine

How do human’s use wind?
• Humans have been harnessing wind since 500-900 AD
• Ancient farmers in Persia used wind power for water-pumping
• Wind power turns kinetic energy of wind into mechanical or electrical power

The Windmill
• Windmills were improved and perfected over 500 years (1300 – 1875 AD)
• Windmills used wind power to turn the rotor (rotational motion) and then transfer this energy to mechanical energy
• To grind, crush, press, or pump

Wind Turbines
• A type of windmill that transforms the mechanical energy of the turning rotor into electricity using a generator
• Much, much larger than windmills• Can have rotor diameters of 145 meters and be as tall as 50 story buildings!!!
• Wind farms are comprised of many wind turbines placed strategically
Wind farm in the Midwest.
