Most drills these days (B&Q commercial, not industrial) is that they are not designed for very heavy use.
A wind turbine is almost continuous use so I'd expect your drill bearings to fail after a few weeks.
A nice "prove it can be done" project but not a realistic long term way to provide power.
Swap out the phosforbronze bearings for sealed for life roller bearings ???
