Question

How many windmills can fit on an acre?

Answer 1

most ordinances, which recently received a favorable recommendation from a majority of state Planning Commissions, would limit the number of wind turbines to one per "property"; set to a minimum "property" size of 2 acres; and create a setback requirement of 110 percent of a windmill's height.

So you would figure out the grid per windmill height, at a minimum of 2 Acres per mill, and the setback allowance.

Keep in mind this is a basis only, every county has its own regulations....especially if you in or near air traffic/approach paths

Answer 2

Wind turbines?  Do you really want how many MW of power per acre?

You could put hundreds of small turbines on one acre, but it's much more efficient to use a few large ones.

a 2 MW turbine will occupy an area of about 72 meters across. You don't want them too close, so I'll use 80 meters. That's a square area of 1600 m² or 0.4 acres.

So you can get 2 - 2 MW turbines per acre.

If you look at a 200kw unit, it takes a space 27-30m across

which is an area of 900 m² or 0.22 acre.

So you can get 4 - 200 kw units per acre. Obviously this is a lot less power per acre than you get with the larger units.

If you buy one at the dollar store, you can fit thousands.
