RenewableEnergy? • Definiton of RenewableEnergy is Energyobtainedfromsourcesthatareessentiallyinexhaustible (unlike, forexamplethefossilfuels, of whichthere is a finitesupply)
Benefits of RenewableEnergy • It is a pollution-free, infinitelysustainablefrom of Energy. • Itdoes not requirefuel. • Itdoes not createGreenHousegasses. • Itdoes not producetoxicorradioactivewaste.
History of UsingWindEnergy • Windenergy has alwaysbeenimportantformankind. • Thefirstinventionthatusedwindtocreateenergy is sails. EarliestRecordsgo as far back as 5000 B.C. ForthefirstsailTransportation. • Wind-Poweredboat has beenmajorcontributortowatertransportation. • This is veryimportantera in historybecausetherewasnowanotherway of transportation in water.
What is Wind? • Wind is the flowof gases on a large scale. • Wind consists of the bulk movement of air. • Long-duration winds have various names associated with their average strength, such as breeze, gale, storm, hurricane, and typhoon. • Winds can shapelandforms. • As a natural force, the wind was often personified as one or more wind gods or as an expression of the supernatural in many cultures.Sothemaingoal is toconvertthisnaturealforceintousableenergy.
What is WindEnergy? AndWindPower? • Wind energy Is the kinetic energyof the air in motion. • The wind has been used for thousands of years as a source of energy. • Wind power is the conversion of wind energy into a useful form of energy, such as using wind turbines to make electricity, wind mills for mechanical power, wind pumps for pumping water or drainageor sails to propel ships.
HowtoconvertWindEnergyintousableWindPower? • WindPower is createdbydifferenttypes of windpowergenerators. • LikeWindTurbines ( UsedforGeneratingElectricity ) , when a lot of windturbinessetup in a closearea it calledWindFarm. • Inthepastpeopleusedwindmills. Windmills are the oldest form of technology used to create wind energy. They were originally created to help pump water for farming and consisted of a tower with a multi-bladed rotary engine. The wind would turn the blades, which would then turn a crankshaft that would pump the water. Windmills can be used for not only pumping water, but also for grinding grain, tobacco and other spices.

ThethingsthataffectsthepowergeneratedbyWindTurbines • Wind • Height • Rotor
Wind • It being a wind turbine, its output first most depends on the wind. Both the speed and force of the wind can be deciding factors. The more wind speed and force you have got, the greater is the amount of power your wind turbine generates. Different regions have different wind speeds. You can gather the available wind dynamics data and using a model like Webull Distribution you can calculate how effective the wind of a particular region is going to be.
Height • Places of higher altitudes have more wind due to various atmospheric factors. Besides, at higher places there is less obstruction from the surrounding hills, trees and building. In fact the height is so important that alternative energy scientists and engineers are trying to use kites (due to the heights they can easily reach) to tap the wind power.
Rotor • The amount of energy produced by your wind turbine is proportional to the size of the rotor used, when all other factors have been taken into consideration. A bigger rotor certainly generates more power. Although it may cost more, in the long run, whenever you are getting a wind turbine erected, go for a big a rotor as possible.
Types of WindTurbines • Horizontal-AxisWindTurbines (HAWT) Havethemain rotor shaftandelectricalgenerator at the top of tower, andmust be pointedintothewind.
Advantages of HAWT • Bladesaretotheside of theturbine’scenter of gravity, helpingstability. • Talltowerallowsaccesstostrongerwind in siteswithwindshear. • Abilitytothrowthe rotor blades in a storm, to minimize damage.
Types of WindTurbines Vertical-AxisWindTurbines (VAWT) Havethemain motor shaftarrangedvertically.
Advantages of VAWT • Can be easiertomaintainifthemovingpartsarelocatednearground. • As the rotor bladesarevertical, a yaw device is not needed, Reducingthecost. • Lowheightusefulwherelaws do not permitstructuresto be placedhigh. • Does not need a freestandingtowerso is muchlessexpensiveandstronger in highwindsthatareclosetotheground. • Usuallyhave a lower Tip-Speedratiosolesslikelyto break in highwinds.
Benefits of RenewableEnergy? • It is a pollutionfree, infinitelysustainable form of energy • Itdoesntrequirefuel • Doesntcreategreenhousegasses • Doesntproducetoxicorradioactivewaste.
Advantages of WindEnergy • Wind is a renewableenergy. • No airorwaterpollution. • ReducesFossilDuelConsumption. • WindPowerPlantscreatemanyjobs. • Increaselocaltaxrevenues.
Advantages of WindEnergy • It’sFree. • Combinablewith Solar Energy. • Thefuel is abundantandinexhaustible. • CleanEnergy-no resultingcarbondioxideemissions. • Modularandrapidtoinstall.
Advantages of WindEnergy • Land friendly-agricultural/industrialactivities can continuearound it. • Generatesjobscomparable in numberstotheconventionalspowersector • PublicSupportforwindenergy. • WindTurbinestakeuplessspacethantheaveragepowerstation.
Disadvantages of WindEnergy • Backupenergyneeded. • WindVariability. • HighInitialinvestment. • Windenergy can not be stored. • Goodwindsitesareoftenlocated far awayfromwhereelectricity is needed.
