Remember no wind, no energy.
Wind turbines are not efficient in collecting all the wind but it has an 80% efficiency rating in generating electricity from the wind. Is the turbine efficient financially?

Transcript of "Efficiency of wind turbines"

  1. 1. Efficiency of Wind Turbines References: Wind Turbines Pros and Cons How Much Do Wind Turbines Cost According to Betz’ Law of Turbine Efficiency, no turbine can exceed 59.3 percent of the kinetic wind energy. Not that the turbine has a 59.3 percent efficiency but that it has a captured 59.3 percent of the wind.For a wind turbine to be 100% efficient it would need to stop 100% ofthe wind - but then the rotor would have to be a solid disk and it wouldnot turn and no kinetic energy would be converted. In opposition isthe fact that one blade would allow wind to go around the blade andmore energy would be lost. The newest designs allow for 70 to 80%efficiency of creating power using the wind.Now is a turbine an efficient way to produce energy? I do not believeso in some markets. If you live in an area where there is little wind,then do not look at this, as the outlay of money does not give you agreat return or savings.If you live in a windy area, where the wind is constant and blowingconsistently, and then look at the wind in your area and the amount ofenergy that can be produced using the wind turbine. If there is enoughwind to power your turbine then you are in business. Remember nowind, no energy.Let us say you live in an area that it is windy some days and somedays not, then you would have to monitor the wind and see if it isfeasible. You can save energy that is produced using batteries tostore the energy, but if you need to live off the storage for more than 1
  2. 2. day imagine how many batteries you would need and how inefficientyour system would likely be.A wind turbine is only as efficient as the wind that is blowing formaking electricity. In some states of the United States, wind farmshave popped up over the countryside. Are they efficient? Some sayyes, some say no! The cost of building a turbine has to be relativelyinexpensive to sell the energy that it produces. If the energy is notcheaper then why build more wind farms?Using the turbines instead of nuclear power or coal burning power is acleaner source of power protecting our future and the future of ourearth. As far as efficiency in keeping our environment green, then it isfar more efficient than nuclear and coal burning. About the only othersource of electricity generation that is as efficient and environmentalfriendly is solar power.Conclusion:Wind turbines are not efficient in collecting all the wind but it has an80% efficiency rating in generating electricity from the wind. Theturbine is very efficient in controlling emission output for electricityversus other power sources. Is the turbine efficient financially? Itdepends on the purpose and where the turbine is to be located. I hopethat we have given you some information to think about to help youmake an informed decision about the efficiency of wind turbines.
