The transmission lines cross state lines, so yes, electricity produced from other sources comes from across state lines as well. Most coal plant retirements will be replaced with natural gas of varying MW equivalents as baseload, but wind energy will continue to experience exponential growth due to costs dramatically decreasing every year.

I can't answer that exact point at the moment, individual turbines have been getting larger and more efficient, producing more MW each. With technology improving I will have to research and see the total number equivalent that would equal.

And a large amount centered around the coal belt/rust belt.

Long term concern I'd never considered until seeing it was mentioned somewhere recently -- who is responsible to take these down when/if they ever become obsolete? (maybe replaced by different energy source?) Besides being huge, they are expensive to dismantle and haul away.

It's kind of the elephant in the room that no one wants to address. In the contract originally given to us by the wind power company there was a "Removal and Restoration" section that stated within 6 months of ceasing operations they would remove the turbines and restore the surface of the land to the same condition it was in at the effective date. What was NEVER established was in the event the company went defunct, who would then have to deal with the structures and grading. The company put the clause in the lease, but had no track record for every having followed through and was real vague about this.

Here's how it's playing out in Illinois:

Wind Farm Decommissioning…Farmer Challenges Engineering Company – *|*Illinois Leaks

Here in Iowa there's a group called "Clean Line Energy Partners" that is trying to use eminent domain to force farmers to accept lines strung across their fields transporting power from the north-central Iowa wind farms to Illinois so Illinois power companies can claim they're using x amount of wind energy. The "Partners" are proposing a dubious plan to use unproven DC transmission. I think they are only in it to get the right-of-way and will immediately sell that to the highest bidder.

I've seen trucks haul wind turbine parts on the interstates... the blades are MASSIVE. The trailers they use to transport them are much longer than the standard 53'. Probably twice as long.

If this is the case, this could really change things for Iowa.
