M4 Discussion 2 (Original Post) Discussion Board 2 (Original Post) Review Focus Study 4.1 (p. 130) Sustainable Resources related to Wind Power. Have you seen a wind turbine where? Is your current location suitable for wind power development? Discuss why. The original post should be posted before midnight as listed in the Calendar for the above discussion topic. T should be insightful, should relate to course materials and provide an opinion and descriptive response. The response posts (in response to at least 2 other students) should be posted before midnight as listed in the for the above discussion topic. It should incorporate previous posts by students, previous posts by the instruc materials and address the question or comment posted by the instructor.

Wind power involves converting wind energy into electricity by using wind turbines. A wind turbine is composed of 3 propellers-like blades called a rotor. The rotor is attached to a tall tower. On average wind towers in residential settings are about 20m high. The reason why the tower is so tall is because winds are stronger higher from the ground and there’s less of a buffeting effect.Wind comes from atmospheric changes; changes in temperature and pressure makes the air move around the surface of the earth; all of which is triggered by the sun. So in a way, wind energy is another form of solar power. A wind turbine captures the wind to produce energy. The wind makes the rotor spin; as the rotor spins, the movement of the blades drives a generator that creates energy. The motion of the wind turbine turning is called kinetic energy, this power is converted into electricity.
Wind energy in South Africa South Africa is blessed with an excellent wind resource and a large land mass. At present. Growing South African Industry: South Africa has the capacity to develop its own wind turbine manufacturing and related industry where many of the components can be manufactured locally.
As mentioned, in most suburban residential settings, solar panels are a better choice than wind turbines.
