Wind Energy
How Do You Get Energy From Wind?
Using a windmill that is mounted on a tower to capture the most energy. Windmills are typically at 100 feet or more above ground, the turbines catch the wind’s energy with their propeller like blades
How Does it Work
Typically about two or three blades are mounted on a shaft to form a rotor. When the wind blows a pocked to low pressure air forms on the downside of the blade. The low pressure air pocket then pulls the blade toward it, creating the rotor to turn, this is known as lift. The force of the lift is actually a lot stronger than the wind’s force against the front side of the blade (known as the drag) so the combination of both the lift and drag causes the rotor to spin like a propeller. The turning shaft then spins a generator which creates electricity.
Cost
~ According to the American Wind Energy Association (AWEA) a small wind-energy system is typically less expensive than its solar powered counterpart.
~ Wind turbines don’t require much maintenance and operate automatically, they also can lower the electric bill by 50 to 90%. A well located wind turbine can pay for themselves within 15 years, or half their useful life.
~ In order to install one, one must have a conditional-use-permit ( wind turbines require building-related permits because of their tall structure), zoning variance, or structural plan that was created by an engineer before beginning to work. The fees for permits and plot plans can cost anywhere from $400 to $1,600, on top of that, public notifications, hearing, and environmental-impact studies may cost another few hundred to several thousand dollars.
