Renewable energy: Windmill

“A transition to clean energy is about making an investment in the future.” An activity to learn the importance of energy, their advancements and future scope is what we are going to learn here along with having a little fun in making a miniature model of a windmill. A wind turbine creates reliable, cost-effective, pollution-free energy. It is affordable, clean and sustainable. One wind turbine can be sufficient to generate energy for a household. Because wind is a source of energy that is non-polluting and renewable, the turbines create power without using fossil fuels.


A windmill is a machine that harnesses the power of the wind. A windmill has a number of blades that spin around when the wind blows on them. The blades are mounted on a tall tower or building. They are connected to a vertical shaft or rod

When the blades spin, they turn the shaft. The turning shaft powers a device that does work. Today modern windmills, called wind turbines, produce electricity for many communities. A group of wind turbines working together is called a wind farm


  • Toilet Paper Roll

  • Chart paper

  • Cardboard

  • Toothpicks

  • Scissor

  • Glue


  1. Take the toilet paper roll and cut it in half and wrap it with chart paper

  2. On the cardboard, make 4 equal size rectangular blades and stick it on the edge of the toothpicks

  3. Take a plastic wheel or you can use cardboard as well, form a wheel structure, and insert the toothpicks with blades on the wheel

  4. Stick this wheel in the top center of the toilet paper roll

  5. Cut rectangular shape cardboard which will act as the windmill base and using a chart paper, make a small cone which will act as the windmill top

Learning Opportunity:

A windmill is a type of engine. It uses the wind to make energy. To do this it uses vanes called sails or blades. The energy made by windmills can be used in many ways. Modern wind power machines are used to create electricity. These are called wind turbines.
