It's ambiguous then as to what cf they mean.
New western offshore wind is in the 40-50% cf range. EU solar is 13% so there's a big range there.
10TW net final energy to replace existing 18TW of world wide primary energy and cover some growth sounds pretty close to most ballparks so 30TW of 30% cf sounds reasonable.
