The energy for an electrical producing Windmill , is created by the wind, or moving air.
Wind energy is harvested by a windmill. It is also called a turbine. Windmills have been connected to machinery to grind grain or pump water. They are also connected to electric generators. The electricity is sent to a grid. Sometimes the electricity is used as it is produced. If a hydroelectric dam is nearby, the electricity can be used to back pump water and then hydroelectric energy is available when it is needed. That way wind energy is stored.
Wind energy can be stored in a variety of ways. One common method is by using batteries to store excess energy generated by wind turbines when the demand for electricity is low. Another method is through pumped-storage hydropower, where excess wind energy is used to pump water to a higher elevation, and then the water is released to generate electricity when more power is needed. Additionally, some wind farms are connected to the electrical grid and feed their excess energy back into the system for use by others.
Turning off lights when they are not needed helps save energy by reducing the amount of electricity being used. Less electricity consumption means lower greenhouse gas emissions and a smaller carbon footprint, which contributes to energy conservation and a more sustainable environment.
A rechargeable battery is a device that can store large amounts of electricity when it is unplugged. These batteries store energy chemically and convert it to electrical energy when needed.
The advantage is that wind is renewable- it does not get used up. Disadvantages- the wind does not always blow, it does not blow at a constant speed, and it does not always blow where electricity is needed. It can be costly to generate and store electricity from wind energy.
The energy from earth is required. This energy is used to create electricity.
Battery?
Most of them use gasoline as well, which would cause pollution. Even if it is completely electric, that energy had to come from somewhere, Like a power plant that produces pollution to create electricity. If you run on only electric, and get your energy from a windmill or waterwheel then it wouldn't!
The amount of airflow required for a windmill depends on the design and size of the windmill. Generally, a wind speed of at least 6-9 miles per hour is needed for a windmill to start generating electricity efficiently. The higher the wind speed, the greater the airflow and power production of the windmill.
wind energy
This energy can be formed either from kinetic/movement energy or potential energy
Electricity is not required for solar panels to collect energy from the sun. However, some sort of device to collect and store the energy is needed for the energy to be useful.

I'm sure you could, if you really wanted to. You could drive a small turbine or windmill blade with the compressed air and couple that to an electrical generator. The downfall would be the practicality. You would be using a compressor to produce the 'energy' needed for this process in the form of compressed air. Any time you use an energy source that takes energy to create, you lose efficiency in the long run. Why generate power with compressed air which took electricity (or gasoline) to create? Just do it with a gas-burning electric generator or the existing electricity for the compressor. In order to be most viable and economical, the process must use energy that doesn't require additional energy to create. In other words, it must be natural energy in the form of sun, heat, wind, gravity (hydro plants), etc.
As long as they have the sun, they can generate electricity. So the Sun :)
The energy is converted into electricity to power your home or any appliances needed in voltage
It is needed if we are to continue to increase electricity production, without using more coal and other fossil fuels
