Wind Power Summary
• Clean• Stable cost• Regional economic development• If wind power is so desirable, why isn’t
there more?

The Nature of Wind Energy
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

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.
