2. Rationale Question: How can we generate electricity using a “greener” method? Why? It provides CLEAN energy Climate change and pollution are ongoing and upcoming problems We should use our natural, renewable resources to provide cleaner energy

3. Basic Generators All generators the same Except solar and fuel cell Parts Rotor Magnets Wires Source: turbines Fuel burning Water flowing Nuclear heating Wind coursing Non-generator sources Fuel cell Photovoltaic cells Choose your favorite! Let’s choose wind power….

4. Types of Turbine Blades Two basic types Vertical Horizontal More efficient Taller Needs adjustment to direction More reliable Vertical Easier maintenance on generator Smaller Slower blades HorizontalVertical

5. Power Generation Efficiency depends on construction, about 20-40%

6. Wind Speed Looking at Indiana…. Decent wind speed in northern half Largest areas of highest wind speed are circled. Wind Speed… Is very important for windmills to work. Units in Meters per Second

7. Wind Power Units in Watts per Square Meter Again, Decent wind power in northern half Largest areas of highest wind power are circled. Wind Power… Actually, more important than speed for the function of windmills

8. Terrain Land cover is important: Developed Land=Bad Forest=Bad Crop areas=Less bad Programs in place for farmers to use their land The previously circled areas are circled again to show that land cover-wise, they should work!

9. Population Wind farms… Take a decent chunk of space Are seen as “ugly” by a large population Should be placed in largely unpopulated areas.

10. Current Locations These dots represent current wind turbine locations. It is important not to put them too close together. It’s also nice to have it a city nearby to send the generated power to.

11. Proposed Location Units in Watts per Square Meter Why here? Low population density High wind power/speed Flat/undeveloped terrain No forests Close to Frankfort

12. Workflow/Standards/Objectives Workflow: Brainstorm energy sources Research energy sources Choose one based on our likings Use research and data to determine best location for a new one Standards (NGSS) MS-PS 3-1 Energy HS-PS 2-5 Electromagnetism HS-ETS 1-1 Analyze global challenge, design/evaluate a solution Stanadards (ISTE) 3.Research and information fluency: Students apply digital tools to gather, evaluate, and use information. Objectives: Students will be able to: Use ArcGIS software Identify sources of energy Propose an idea for a new electric generator location.
