Full Answer

The sun heats the atmosphere, but it doesn't do it evenly. This process, along with the rotation of the earth, causes winds that scatter across the varied surface of the earth. That wind can be harvested by wind turbines. The wind turns the turbines, which generates electricity.

The turbines are connected to shafts. When the turbines turn, the shaft turns. The shaft then turns a generator. The turning of the generator creates a flow of electrons, which is electricity. Wind turbines automatically shift to harness the most wind power, based on which direction the wind is blowing.

Two basic types of wind turbines exist. Some spin vertically, like the giant turbines on wind farms that look like pinwheels. Other turbines spin horizontally; these types can be used on the tops of buildings to generate energy.

Turbines on wind farms can produce up to several megawatts of energy, though some produce less. They are grouped together to produce power on a grid. Blades on a large vertical turbine can be as long as 100 yards. Smaller turbines produce less than 100 kilowatts of energy. These types are used in residential areas for homes, and they are usually employed by themselves, though sometimes they work in conjunction with power from the city.

    What is an LED voltage drop?

    A:

    An LED voltage drop describes the diminishing of the brightness of LED lights on a strip the farther the lights are from the power source. This is because voltage diminishes along the length of a wire the farther the electricity moves away from the source.

    How does a light bulb circuit work?

    A:

    A light bulb circuit works when the electric current flowing through the light bulb combines with the current flowing in the battery or power source. The filament and wires in the light bulb conduct electricity so that electric current can move through an electric circuit.
