three if you look at any wind-generated power stations you will always see three blades.
Weather creates masses of moving air. Some of the energy of the air can be captured by a windmill or wind turbine and converted into another form. In a modern wind turbine the blades are aerodynamically shaped to get the most power from the wind. The blades turn a generator which produces electrical energy.
there is three or four
Blades
Wind energy is derived from wind mills. These wind mills are powered by the wind and capture it's energy when it blows.
because they will not spin with out them

the reason there is only three blades is because four blades would add weight and wind resistance, in some countries they use two or four bladed turbines though. \

There is no key, but there are three windmills you have to blow in to. There will be a map. When the wind is blowing click on the map and it show an x. Go there and it will show you the three wind mills you're supposed to blow into. Blow into the three wind mills and the door will open

Farmers used wind energy, the wind mills also pumped water as their blades swung.
yes, he used materials from a local scrap yard. He did not copy the design from the book, instead of using 3 blades he used 4 blades.
wind turbines, wind mills.
A wind machine with blades is so called a wind turbine, or a windmill.
