Wind power does work, but it's very site-dependent. The power in wind is also a cube of the wind speed... and wind speed increases the higher you go. This is why turbines that work are tall (120'+ to get away from ground turbulence), and are sited in spots that have *constant* wind... ideally 7mph or more. I'm sure no one wanted 120' towers at this site, but that's really the way to get wind power... but even then, this site doesn't always have wind. Along Ediz Hook would be a better location (as long as turbines didn't interfere with approach to airport out there)

An option for this park site given its occasional wind could have been solar PV panels; 3kW of PV panels (about 12 panels) might have cost $15k and would be generating electricity already, because all commercial PV components are UL listed. The ROI on PV these days is maybe 10 years with minimal tax / production incentives, (5 to 7 years with incentives) and the maintenance is minimal... no moving parts!
