My little guy is studying renewable energies in school so I put this little bit of a lesson together - partly so that he learns more about what inspires him and partly because I wanted to make a windmill :-) Enjoy! Wind Power is energy that is made directly from the wind. The wind turns a windmill:  which then turns something that needs to be turned - like a flour mill (grinding the flour): Or pumping water: But the windmills that are corporate windmills that we see today are called wind turbines. They are set up as "wind farms" that use the wind to "farm" or create energy.  Meet the wind turbines! These mighty machines stand over 300 feet tall with blades that are over 100 feet long! How big is that? Well the towers are are as tall as the statue of liberty and the blades as long as well - this fire truck ladder! The gist of how a turbine works is that is works the reverse of a fan; instead of the blades pushing the air like in a fan - the blades are pushed by wind
