Two types of wind turbines:
horizontal and vertical axis
Horizontal Axis -
baldes catch wind and spin - Generator converts mechanical energy into electricity - cable connects electricity to transmission line - computer system controls direction of blades
Vertical Axis -
darrieus wind turbine in martigny, switzerland
What state is the potential for wind energy high?
North Dakota
