It's much more complex than this. You can't run a data center on wind. Data centers are all grid connected, so what really matters is the composition of generators on the grid (or at least the composition on the generators near the datacenter).

You certainly could run on it on a dedicated combination of any mix of wind/solar/hydro power and stored (e.g., battery or regenerative fuel cell) power you wanted to.
In practice, you'll probably want to connect it to the grid, but directed purchases on the grid, while they don't actually select which source really powers the DC, have all the practical effect of doing so.
