Ventera 10kW turbine <br />Putting a turbine <br />on too short of a <br />tower is like placing <br />a solar panel in <br />the shade. <br />Restrictive Zoning <br />Rules Can Undermine <br />State Law <br />Several states offer <br />financial incentives to <br />promote small wind <br />turbines and clean <br />energy. But zoning <br />height limitations can <br />prevent.turbines <br />from generating any <br />meaningful amount <br />of energy, thwarting <br />the intent of the <br />state incentive. <br />THE IMPORTANCE OF HEIGHT <br />Why Do They Need To Be Tall? <br />A tall tower is the single most important <br />factor in the economic viability of a <br />small wind system. Tall towers enable <br />turbines to access faster and better. <br />quality winds, and even small increases <br />in wind speed translate to exponentially <br />more energy the turbine can generate. <br />In other words, a taller tower means <br />far more - and cheaper - energy. <br />The best sites for turbines are those <br />where the wind is least obstructed, <br />which is often the highest point on.a <br />property. The bottom of the turbine <br />rotor should clear the highest wind <br />obstacle (roofto.p, mature tree, etc.) <br />within a 500 foot radius by at least <br />30 feet. Doing so ensures the turbine <br />reaches consistent, fast wind speeds <br />and prolongs the life of the turbine by <br />avoiding stressful air turbulence. <br />PRExi�[ILii+lG 1ta►IhID <br />50o feet <br />i+3ind &peals Increase with Haight <br />400 -watt <br />p 9 <br />75 10 124 <br />inrea in Med Power_ % . <br />io7kiiowatt <br />8Q'=120` <br />tower <br />
