Why can't we predict turbulence deterministically?
We can predict and analyse turbulence, and frequently do. That's one of the things that Computational Fluid Dynamics models do, and what weather forecasting models do, and what climate models do, ... …

Windmills in empty fields. Why no trees?
Trees increase the turbulence of the air that reaches the turbines. That creates all sorts of uneven, rapidly-shifting loads on the blades and structure. That increases the maintenance costs, decrease …
