Lightning isn't that energetic. A 16 MW wind turbine can capture the energy of a lightning bolt from thin air in about 1 minute.

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.

With an average duration of 0.2 seconds, a bolt of lightning therefore has like 355 times the energy of your wind turbine for the same length of time.

Sounds fairly energetic to me.

Sounds fairly powerful to me.

If you assume that it takes a while to build up for a sudden discharge, that doesn't sound like that much to me.

Also we don't know how much atmosphere-volume per second is needed for 1 "normal" lightning strike. (Assuming some sort of volume-based cause.)

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.

Have you ever seen a thunderstorm averaging five lightnings per second? I haven't. But I have seen plenty with a couple lightnings per minute - right in the ballpark of the power of a small wind farm beneath.

For the curious: https://en.wikipedia.org/wiki/Catatumbo_lightning:

“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.

Back in 2017 there was a superstorm over the UK and France. Here in London the lightning was basically continuous. It was really bizarre because it looked like someone had put stadium lights on so the whole sky was lit up continuously.

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...

Yes. I once drove through a storm which lasted well over an hour, with continuous fork and sheet lightning around the entire horizon. An absolutely fantastic sight, never seen such a dramatic spectacle before or since, it was absolutely stunning.

New Mexico fall thunderstorms can do one every 2-3 seconds for a minute. And the storm itself will last for hours, even though it calms down a little. Lightning radar apps show a 30 minute window of lightning and can fill up areas of the map with just solid yellow from the overlapping bolt icons.

I've seen a couple with a bolt every couple seconds. More or less continuous lightning.

You're mixing energy and power.

Yeah and a huge rock you roll up a mountain will fall with huge force in a few seconds, it doesn’t mean it has any more energy than what was used for elevating it.

The auroras aren't caused by the Sun's electric field impinging on the Earth, they're caused by actual charged particles from the solar wind entering the atmosphere and ionising air molecules.

They did say that it was the leading hypothesis that this puts aside.

How does sun send its electric energy to a 70m wide region of the cloud? Aurora borealis is 80-1000km across.
