We don't need both. We actually just need nuclear, and no amount of throwing away my tax money on wind boondoggles will change that. The Norwegian Labour Party royally screwed the Norwegians with wind, they had to make all other energy much more expensive to make wind feasible, and wind is still not feasible, everything else is just ungodly expensive with 5% monthly inflation on food.
That sounds like a political problem in one country, not a wind problem.
Wind works well, especially offshore: there are 1133 GW of installed wind capacity globally in 2024, so it seems to be working for somebody. This is compared to 377 GW of nuclear globally.
