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.

Long Blades Catch More Wind Then Short Blades
Yes, they move to catch the wind.
Windmills are much shorter than wind turbines, and usually have many blades. The blades catch more wind causing the windmill to be able to do more physical work. The propeller blades are connected to an axle with gears. The gears are connected to a vertical shaft that runs down the length of the tower and is connected to other mechanical equipment. Windmills do work such as pump water or grind grain, which is why they are a common site on farms where they are used in crop production. They are not built to produce electricity.HOPE THIS HELPED!!!!!!!
Yes, wind turbines can catch fire due to mechanical issues, electrical malfunctions, or lightning strikes. However, modern wind turbine designs incorporate safety features to minimize the risk of fires and to detect and suppress fires when they do occur.
Wind turbines are designed to catch the wind and create electricity from the wind energy. The power station of a turbine moves the unit so the fan blades face the wind so the force of the wind can rotate the fan. The concaved blades collect the wind and send the force down their pedestal to produce energy with the help of a generator. The more wind that is collected, the more power produced.
The wind farmers usually want to spread them out so the propellers do not collide. They also want to spread the turbines out so that they can catch the wind wherever it is.
Windmills have blades that are designed in a way to catch the wind and turn it into rotational energy. The curved shape of the blades creates lift, similar to the wings of an airplane, allowing the windmill to capture the kinetic energy of the wind and convert it into mechanical energy used to generate electricity.
The blades of a wind power generator catch the windThe wings if an old fashioned wind mill catch the wind
Windmills have blades that are designed to catch the wind, causing them to spin. The rotation of the blades drives a generator inside the windmill, which then converts the kinetic energy of the wind into electrical energy.
This relates to airflow in each of the fan blades. When the fan blades spin, the blades will catch the air and will start to vibrate as a constant process of being pulled back by the air and the blade's elasticity dragging it back to its previous position.
Wind is a renewable resource on earth. Wind turbines can be used to catch the wind's energy and be used to create electricity.
