Betz 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 energy 8/30

• Upwind 3-blade design is dominant

• Active pitch or passive stall

• Direct drive versus gearbox

• Variable speed versus constant speed

Capacity Factors

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

Capacity factor depends on turbine design and wind speeds

14/30


Power Output:2628 MWh per year is enough for 260 typical homesMore if homes are more efficient

Wind Economics

• No fuel cost• Stable fuel cost• Strong correlation to load requirement

–More production in winter–More production on windy days–More production during the day

Wind Turbine Land Use

• Wind farms use 2% of the land for foundations and roads

• 98% of land available for other uses

• Compatible with pasture, crop, bike path, recreation, industry

• Multiple uses/productivity24/30


Wind Turbine: Sound

• Should be located up to 350M away from residences

• Sound is swoosh, swoosh – not mechanical• Can carry on a conversation at the base of

the tower• Sound is greatest when windy, when

ambient noise is greatest too.
