Well I'm not sure where to start. To start with, I am all for wind energy production. I worked in wind energy for 7 years and worked on all sorts of windimills from small 12 volt dc mills to 44 ft diameter, 60 kw commercial units.
First of all You need wind. 11-12 mph average just to break even. That doesn't sound like much but it is. Yes there is that kind of wind on mountain and ridge tops but once you drop off the ridge or mountain top you don't have enough. Ice skating rink in LP doesn't have enough, the ski jumps don't have enough.
Next you need good wind. This is wind that flows smoothly without turbulence caused by the ground or surounding features such as other ridges, trees. or even other windmills. That's why the windmills are on towers even though they are on high ground. If the wind is turbulant the mill spends it's time yawing back and forth in the wind.
Next you can't stick them on any old tower or building. For one thing they sometimes fail; Sometimes they fail catastrophically. I was once sent to Palm Springs a week after we had two windmills come down due to mounting bolt failures. You see these windmills in the beginning of the movie Rain Man when Tom Cruise get's the call his father has died. In that scene you can see how far from the highway those mills are. At least 100 yards. The blades from one of the failed mills landed in the road. A failure of even a small windmill on a lift tower? Forgetaboutit.
One of the design problems windmill manufacturers have to over come are tower dynamics, that is the relationship between the vibration that the windmill produces while operating and how the harmonics in the tower react to the to those vibrations. We've all probably seen the
bridge in Tacoma, WA that went down because of the harmonic vibrations setup by the wind. That happens when windmills are put on things that aren't designed to hold them.
So While I would also like to see the developement of wind energy, it just ain't that easy.
