Nice contrast between old and new technology. The 3 on the bottom are equal to most if not all of the small units on top.

Yes; and they are probably 30%-35% load factor, which is a slight improvement (that means they are available for meaningful use for about 1/3 of the time, not when needed for peak, necessarily). When the wind dies, an alternative source is needed, or your lights are out!

Modern portable outhouses probably are more aesthetic than the old shacks, too, but they STILL are not desirable in the middle of a residential community (and are probably as welcome as a 200 foot propeller on a 250 foot pole).
