I'm genuinely curious about this, why the fascination with offshore specifically?  Not just in Ohio but globally?  Is it because the wind is more reliable offshore?  Or just land use and permitting headaches onshore?  We're not exactly land-poor onshore even in Ohio, and in places like Texas and much of the Great Plains and Southwest, they've got tons of land with tons of reasonably reliable wind.

I thinks it's because so much potential lies off shore. You can see on the map that the greatest wind resource is by far the coastal areas.

Also, the Ohio legislature enacted fairly strict setback requirements a couple years ago that make land-based turbines relatively difficult to site. No doubt somewhat hyperbolic, but Amazon described them as "an effective moratorium of sorts on new wind development."

Wind turbines can be a little rough on birds, to say the least.  There aren't as many out away from the shoreline, and the mess isn't an additional issue.

^Yeah, wind turbines do pose a risk to birds and will kill some, potentially millions per year.  But the risk isn't unique to turbines and is mostly caused by the tower itself and not so much the spinning blades.  So the risk is really on par with any communication tower or large building. 

Modern large turbines spin at relatively slow speeds so the risk of bird death due to impact with a blade is limited to the last 1/3 or so of the blade (near the tip) which passes through any given point in space less frequently than the smaller blades of the past.  The belief that wind turbines are bird blenders started because the old, small turbines at Altamont Pass do kill thousands of birds per year, but the new turbines are much better and kill far fewer birds.  While mitigation efforts are warranted, especially for certain migratory bird paths, it is certainly no reason to curtail wind energy development in my opinion.

non-flashing tower lights may increase risk to birds..

Terminal Tower turns off the colors between midnignt or so and 4am for this reason.

interesting -- from the city website i saw bg's wind farm debt was all paid off early:


WIND TURBINES

Bowling Green is home to Ohio’s first utility-sized wind farm. There are four turbines that are 257 feet tall. These turbines are as tall as a 30-story building and generate up to 7.2 megawatts of power — enough to supply electricity for approximately 2,500 residential customers. Located about six miles from the city, the turbines can be seen for miles and have become a local attraction.

Debt on the wind turbine project was paid in full in 2015.   This is a tremendous accomplishment as the debt was paid off several years early and the project is now one of the City’s lowest energy resources.

You know what's infinitely worse for birds than wind turbines in the Great Lakes? Fossil fuels and climate change. https://t.co/22zF7qcEYH

Just a reminder that coal kills at least 24x more birds than wind turbines https://t.co/nQFpLuwgz6

Spliethoff is bringing the heavy lift ship Happy River into Cleveland April 25th, the day after the arrival of their regular liner service ship. I wonder if Happy River will be carrying wind turbine components. The caissons look massive.
