No; when wind blows the blades of a windmill, that's mechanical energy.

What is a structure called with revolving vanes?
A windmill is an example of a structure with revolving vanes.
How do weather vanes work and what materials are the usually made of?
Weather vanes work by using the force and direction of the wind to determine which way it is blowing. They typically consist of a rotating arrow that points in the direction from which the wind is blowing. Weather vanes are commonly made from materials such as copper, stainless steel, or aluminum, which are durable and weather-resistant.
Why do farmers use wind vanes?
Wind vanes are used to tell the direction in which the wind is blowing. Farmers would use it to tell the direction of the wind when out in the field.
How does wind energy help wind turbines work?
Wind blows on a windmill or wind turbine and makes it rotate. This can be looked at the kinetic energy in the moving air being converted to the kinetic energy of the rotating vanes. The rotating turbine turns a shaft that turns (through gears) a electrical generator. The generator produces electricity. This can be seen as the kinetic energy of the rotating vanes transferred to the kinetic energy of the generator, which converts it to electrical power. The electrical power is then sent into the electric grid.
What is another name for the sails of a windmill?
I don't think there is another name other than blade.
What is the meaning of windmill?
A mill operated by the power of the wind, usually by the action of the wind upon oblique vanes or sails which radiate from a horizontal shaft.
Why is it important for meteorologists to keep track of the data given by weather vanes and anemometers?
A weather vane is an instrument that is used to show the direction of the wind. These weather vanes are produced with equal weight on either side of a rotating axis with one side being larger. The arrow pointer of a weather vane will point in the direction that the wind is blowing.
What do you know about windmills?
A windmill is a machine that converts the energy of wind into rotational energy by means of vanes called sails or blades. The reason for the name "windmill" is that the devices originally were developed for milling grains for food production; the name stuck when in the course of history, windmill machinery was adapted to supply power for many industrial and agricultural needs other than milling. The majority of modern windmills take the form of wind turbines used to generate electricity, or wind pumps used to pump water, either for land drainage or to extract groundwater.
What a wind vane measure?
It shows the direction where the wind is coming from. Like the North, South, East or west. Weather vane or wind vane does not measure anything, it just shows the direction the wind is out of, a wind monitor measures the force the wind is blowing, in mph or kph. Wind vanes indicate wind direction and when this information is recorded, describes the direction FROM which the wind is blowing. Wind vanes measure the direction in which the wind is blowing. anemometer The direction the wind is blowing from. So it measures wind direction.
How is electricity generated by a generator?
Energy doesn't 'take place'. Until you become more comfortable with it, you should think of it as some kind of fluid, that flows from place to place, and can be stored in several ways for when it's needed. An electric generator is a machine that has a shaft and two terminal connections. It can supply electrical energy through the terminals when you spin the shaft. You just have to find something else that has energy, and skim energy off of that to spin the shaft of the generator. Some possibilities are: -- wind turning a windmill coupled to the shaft -- water falling through vanes on the shaft -- fire boiling water and blowing the steam through vanes on the shaft -- uranium in a nuclear reactor getting hot and boiling water and blowing the steam through vanes on the shaft -- a person pedaling an exercise bike coupled to the shaft -- 400 hamsters running on a treadmill coupled to the shaft. In every case, it takes 'kinetic energy' to spin the shaft, and the generator converts that kinetic energy into electrical energy.
Who uses a wind vane?
To see from wich way the wind is blowing. eg: if the arrow points to the east= wind comes comes from the east.
What is a wind vane made fom?
A wind vane is an instrument that tells a person which way the wind is blowing. Weather vanes are usually made out of a metal surface, like iron.
