NC GreenPower :: Types of Renewable Energy

	Renewable Energy > Wind
	For centuries civilizations have taken advantage of the wind’s energy. Once used primarily on farms for pumping water or grinding grain, the windmills of the past have been updated to generate electricity without harming the environment.
	Today’s wind turbines are mounted on tall towers – at least 100 feet high – to catch the wind’s energy more efficiently. Propeller-like blades on a shaft form a simple rotor – new models have even been designed to protect birds. As the wind blows the rotor, the turning shaft activates a generator to make electricity. Electricity providers often use wind farms – many wind turbines built close together – to supply power to their customers. However, the providers work hard to balance the need for electricity while preserving the scenic vistas in coastal or mountain regions.
