The Nature of Wind EnergyBetz LawThe maximum power that can be captured from the wind is 59% of the kinetic power in the wind

Today's turbines capture > 50% of the total power in the wind

High pressure, cold air has more energy8/30soheil6886.blogfa.com

Capacity FactorsExample:1MW unit at 30% capacityProduce 1MW x 30% x 24 x 365 = 2628 MWh per year

Capacity factor depends on turbine design and wind speeds14/30soheil6886.blogfa.com

Power Output:2628 MWh per year is enough for 260 typical homesMore if homes are more efficientCapacity Factors15/30soheil6886.blogfa.com

Wind Turbine Land UseWind farms use 2% of the land for foundations and roads98% of land available for other usesCompatible with pasture, crop, bike path, recreation, industryMultiple uses/productivity24/30soheil6886.blogfa.com

Wind Turbine: SoundShould be located up to 350M away from residencesSound is swoosh, swoosh not mechanicalCan carry on a conversation at the base of the towerSound is greatest when windy, when ambient noise is greatest too.25/30soheil6886.blogfa.com
