Average Wind Farm Size & Energy Production

[optimizer]

Hi,
With all the wind farms being put into production recently, does anyone know what the average size generally is. I see they are generally between 10-kW to 5-MW, quite a difference, so I would think the large ones can only be used in certain places and need to be spaced apart more - but I could be wrong, and they might be trying to install bigger ones everywhere.
1/ What size do they generally use, and
2/ how many Joules do they produce per day (on average).
3/ How many pounds of air do they process to produce that energy.
Thanks
Links always welcome.
Physics Dummy as always (but less so with more posts/answers!)

Employed today are two kinds if I were to categorize them myself. There is the one-giant-huge-wind-generator, and there is the very-large-array-wind-generator. The one huge generators usually are out in the ocean somewhere off the coast of Spain, the Netherlands, or in the Gulf of Mexico. The very large arrays are a lot of smaller ones. They are probably a little bit taller than telephone poles? Both kinds are VERY loud.

It's the average sized one I'm trying to get the information on (?kW ?MW ?).
Maybe there is an average for offshore and an average for onshore.

1/ What size do they generally use, and
2/ how many Joules do they produce per day (on average).
3/ How many pounds of air do they process to produce that energy.

Yes, I know air is generally a volume, but I'm trying to relate it to a weight dropping in gravity.

There is a force of air pushing the blades that could be measured in ft lbs.

I suppose I'm trying to think of it / translate it as a column of air dropping through a blade (or a blade dropping thru a column of air), and how long the column of air is on an average day.

Maybe I'm not getting anywhere on this one, so back to the drawing board. :uhh:

I am interested in the averages (onshore / offshore), and the Joules, and the volume per day.

Thanks
