Did you know that wind is used to produce electricity by converting the kinetic energy of air in motion into electricity? Today modern wind turbines rotate the rotor blades, which convert kinetic energy into rotational energy. We call this rotational energy and it is transferred by a shaft to the generator, thereby producing electrical energy.
According to the office of energy, there are advantages and challenges to the wind energy.
Advantages:
- It is cost-effective
- It is clean and renewable energy source
- It is a domestic resource that enables U.S. economic growth
- It benefits local communities
Challenges:
- Wind plants can impact local wildlife
- Wind power must compete with other low-cost energy sources
- Turbines produce noise and alter visual aesthetics
