Its a good thing you know exactly what removing energy from a localized marine environment will result in. To the best of my knowledge even the PhD's in the field don't know - because it hasn't been done.
You watch Jurassic Park? Read the book?
No. Now they just quote directly from the latest top gear.
Small enough that slowing down currents and water motion for several miles might screw with the local marine life... or alter the gulf stream... or erode the ocean shelf.. who knows the exact affects?
Aside from making it illegal to boat anywhere nearby.
First off these are by no means perfect solutions themselves. They're expensive for the power generated, are subject to the whims of nature and of course, could affect surrounding nature in unforeseen ways. What happens when you cause large dead spots in the ocean or wind currents? Have any real life tests been performed?
Personally I don't like the idea of off shore power generation, I'm sure it would expand and screw up the laws for sailors and the sea. Not to mention the large zones a few miles off shore that would be off limits to the public.
You also forgot to mention nuclear power, which beats everything else atm. If power companies want to experiment with this stuff i say go for it, but to realistically solve power needs with reliability America needs to get its nuclear ass in gear.
I was born and raised in Manassas, VA - I never heard of or saw this IBM building... how long ago was this?

"Baby you know I do!"
