Coriolis force is a fictitious force (like Centrifugal force). Anyway, force has to move a distance to create work (energy). Wind energy is the result of wind, which results from large convection currents due to temperature differences on earth, both due to latitude (tilt of earth) and difference in specific heat (thermal capacity) between land and sea. Since these uneven temperatures are caused by sun's radiation, wind energy is just solar energy. Wind mills are parts of a giant heat engine (just as a turbofan in a jet engine). So, windmills will not result in slowdown in rotation of earth. But, they will lead to a miniscule amount of cooling locally (the wind on the outlet side will be a tad cooler than on the inlet side). However, this will all get evened out since most of the power produced eventually becomes heat anyway.
