Ugh, wind dropped ~11% in 2021? I heard new capacity has paused for some reason. Is this just that + old capacity being retired? Or just some temporary downtime

Ugh, wind dropped ~11% in 2021? I heard new capacity has paused for some reason. Is this just that + old capacity being retired? Or just some temporary downtime for maintenance? Or is it just that 2020 was super-windy and 2021 was calm? Seems like a big change.
