write advantage and limitation of wind energy?
Answers
Advantages:
Wind power is cost-effective.
Wind creates jobs.
Wind enables U.S. industry growth and U.S. competitiveness.
It's a clean fuel source.
Wind is a domestic source of energy.
It's sustainable. Wind is actually a form of solar energy.
Wind turbines can be built on existing farms or ranches.
Disadvantages:
Good wind sites are often located in remote locations, far from cities where the electricity is needed. Transmission lines must be built to bring the electricity from the wind farm to the city. However, building just a few already-proposed transmission lines could significantly reduce the costs of expanding wind energy.
Wind resource development might not be the most profitable use of the land. Land suitable for wind-turbine installation must compete with alternative uses for the land, which might be more highly valued than electricity generation.
Turbines might cause noise and aesthetic pollution. Although wind power plants have relatively little impact on the environment compared to conventional power plants, concern exists over the noise produced by the turbine blades and visual impacts to the landscape.
Turbine blades could damage local wildlife. Birds have been killed by flying into spinning turbine blades. Most of these problems have been resolved or greatly reduced through technological development or by properly siting wind plants.
Advantages: It is abduntly available in nature. It can be used again and again.
disadvantages:1. wind power plant only implant where the wind velocity is high
eg. Coastal region.
so it cannot be used everywhere.
2. It maintenance is costly.
