Sounds fairly energetic to me.

In contrast, the amount of air passing through the blades of a turbine per second is probably much easier to calculate, and I'd wager less.
“Catatumbo lightning (Spanish: Relámpago del Catatumbo) is an atmospheric phenomenon that occurs over the mouth of the Catatumbo River where it empties into Lake Maracaibo in Venezuela. It originates from a mass of storm clouds at an altitude of more than 1 km, and occurs during 140 to 160 nights a year, nine hours per day, and from 16 to 40 times per minute”
That seems to be the most one gets on earth, but there, it isn’t rare.
Apparently there was something in the region of 120,000 lightning strikes over 12 hours, which is 10,000 per hour. That was, of course, spread over a large region, but still...

The average lightning bolt that strikes the ground contains about 1 billion joules of energy. That's 1 GJ of energy.
The Siemens Gamesa’s SG 14-222 DD wind turbine has a capacity of 14 MW. In 71 seconds that wind turbine would capture the energy of a lightning bolt.
There is an enormous amount of energy in the air moving around us. I can very well believe how that movement can charge up lighting.
