Parts of a Windmill
Fossil fuels such as oil and coal are nonrenewable, that is, they draw on finite resources that will eventually dwindle, becoming too expensive or too environmentally damaging to retrieve. In contrast, renewable energy resources such as wind and solar energy are constantly replenished and will never run out.  Most renewable energy comes either directly or indirectly from the sun. Wind Turbines have a long history and they date back to the ancient times.  They have been used through history and they are still in the process of development. Windmills may be used to do a work such as grinding grain into flour or pumping water out of a water well. They may also be used to create electricity. 
In this project we will study the parts of a windmill and make a model of a windmill.
Material and instructions:
Making a model of a windmill is a good way to learn about the windmill parts. You may also use your model to do some additional experiments and see how much wind power can be converted to work in your windmill. When you select this project, you can also study questions such as:
  • Which blade variables have the greatest affect on windmill efficiency?
  • What is the effect of wind speed on energy production of a windmill?
