Tall wind turbines needed

To the editor: Since 2005, monthly surveys have shown majorities favoring megawatt-scaled wind energy by nearly 6 to 1. A powerful, tightly organized, Beekmantown minority opposes it. Veiling it by claiming winds acceptance, they assert winds not worth having beyond small stand-alone (and expensive) individually-owned toys. Every height increase reaches faster winds, with therefore more kinetic energy. Since kinetic energy is half mass times its velocity squared. Its velocity increase, raises energy by the square of that increase that is, the increase times itself. Thats a lot! Its why, as windplants height rises, they become significantly more competitive against big steam plants. To protect delicate turbine blades against premature breakage due to material-fatigue-inducing flexing from gusting and wind-direction changes caused by turbulence from locations below interfering treetops also matters. Windplants need enough height. To encourage wind energy, back when small household devices was all there was, laws were adjusted requiring utilities to buy small winds output at retail rates. That quietly raised non-windmill-owning consumers electric bills. Megawatt-sized machines can yield profit without raising our rates! According to environmental activist, Charles Komanoff, since wind costs less per kilowatt-hour generated, operating engineers run it preferentially over steam. More electrons from wind power mean proportionately fewer from steam. With very few exceptions, ... wind ... can be counted on to displace (steam) one for one, wrote Komanoff. Letting the free market shut down big dirty coal and nuclear steam plants from winds competition, is a tall job, requiring tall turbines. With its free fuel, wind energy can displace coal and nuclear steams megawatts, but needs is own megawatt-scale to do it. Under laws too restricting of its dimensions, it cant. We want it, wherever windy enough, the taller the better. Restore majority freedom. Resume representative democracy. David E. Manwell, Beekmantown
