Since there are periods when the wind doesn't blow, storage is essential...and that is VERY COSTLY...
Case in point...in May/June of 2018, the U.K. experienced a "Wind Drought" that lasted for 13 days affecting its on-and-offshore wind farms...if they had no other sources of power, then the storage costs for batteries (e.g. Tesla 'PowerPack 2' commercial units @$160K ea.) would have been $1.2T for that time period...just for the battery costs, irrespective of all other necessary costs for operation and maintenance, etc....ALSO, batteries don't last forever, as we all know, and that investment would need to be repeated every 15-20 years...while a nuclear plant would continue to operate with 90+% availability for 60 years (as they do now).
Then there's the land use issue for Wind Power...you can only get 3W/sq. meter from wind (that's already been assessed), so just do the math on how much land is required to power the country...
But Wind Power does work...intermittently...so we need to identify uses for it with that caveat in mind...and where storage costs don't have to be so onerous.
