Use of even a few percent of this resource would obviously have a beneficial impact on the States economy. Types of wind machines A wide variety of types and sizes of wind machines exist today. Wind turbines are classified into two general types, drag and lift. Drag devices characteristically produce high starting torque and are well suited to pumping water in low volumes, however they are limited in the amount of energy they can extract from the wind. One blade rotating very fast can extract as much energy as many blades rotating slower.
Lift devices use slender airfoils for blades, whose shape is the same as an airplane wing.
Lift devices are much more efficient than the drag devices, thus the blade area can be reduced considerably. The map delineates the wind energy regions of the State. Since power and energy are closely controlled by windspeed, the power at a particular location is dependent on local terrain and obstructions. Those regions enclosed by contour lines are suitable for the installation of wind turbines. Of course, wind turbines located at sites with higher windspeeds will produce more energy.
