Description should include the
- limit (theoretical) that at optimum conditions, approximately 58 percent of the wind's energy can be converted to electrical energy as a result of aerodynamic drag, mechanical resistance, etc.
- concept that energy is neither created nor destroyed, only transferred among forms.
Process/Skill Questions:
- What technologies could allow wind turbines to reach their maximum efficiency?
- What practical limits are there on the amount of power that can be derived from the wind due to the conversions that are necessary?
