Perhaps it would help you to abstract this a bit.
Remember in school all of those math problem solving exercises?
The ones where there was a bunch of stuff on the left side, and bunch of stuff on the right side, and an "equal sign" in the middle.
That equal sign was pretty important wasn't it?
Why was that darn thing there anyway you probably asked yourself over and over and yet nobody could give you a satisfactory answer.

What I think
aerohead is saying, is that to solve for this problem, both sides of your equation have to equal each other,
or complement each other in some way. You cannot have an unequal equation, gotta account for everything or you missed something.
Inequalities ppt revised
Perhaps if someone wrote out an equation showing the energy into the system (power generated), energy out of the system (power used; air drag, rolling resistance)
which included the wind turbine as a factor we could all visualize this in a simplified manner and know which category to put things in.
Often defining the problem leads to solving the problem.
In other words, if you cannot define your problem, then you have little hope of solving it.
Identifying the problem is key to it's solution.
You cannot hit what you cannot see, so stop squinting so hard.
