Wind Advantages And Disadvantages

VAWT disadvantages

 Most VAWTs have a average decreased efficiency from a common HAWT, mainly because of the

additional drag that they have as their blades rotate into the wind. Versions that reduce drag produce more

energy, especially those that funnel wind into the collector area.

 Having rotors located close to the ground where wind speeds are lower and do not take advantage of higher

wind speeds above.

 Because VAWTs are not commonly deployed due mainly to the serious disadvantages mentioned above,

they appear novel to those not familiar with the wind industry. This has often made them the subject of

wild claims and investment scams over the last 50 years.

ADVANTAGES AND DIS ADVANTAGES OF WIND POWER:

1.The wind is free and with modern technology it can be captured efficiently.

2. Once the wind turbine is built the energy it produces does not cause green house gases or other pollutants.

3. Although wind turbines can be very tall each takes up only a small plot of land. This means that the land below can still be used.

This is especially the case in agricultural areas as farming can still continue.

4. Many people find wind farms an interesting feature of the landscape.

5. Remote areas that are not connected to the electricity power grid can use wind turbines to produce their own supply.

6.
