Global wind energy will exceed 1 TW by the end of 2023

One year's worth of power generation.

That's not the unit used. It could be instantaneous maximum, mean, or some other fiction.

I stand corrected. I got confused between 'nameplate capacity' & 'capacity factor'.

I believe it's a measure of rated output power. The article's headline confusingly refers to energy.

1 TW of capacity. Meaning if all the wind turbines are collecting the maximum that they can, 1 TW is the power we get.

If you need a time unit, think of it as 1 TWh every hour.
