If you mean how to turn the energy in the wind into electricity in the first place (rather than transporting it to the grid) there are two basic ways: Ground generation, where you let the kite unwind the tether and have generator connected to the spool. Occasionally you need to expend energy to wind it back up, but this can easily be made work out as a net positive. Airborne generation, where you have small turbines with generators on the wing and lead the power down through the tether.
