How dom you measure the energy created by a windmill?
It depends on what you do with the windmill. The most basic measure would be average revolutions per minute over x period. If you were using the windmill to make electricity then you would indeed use the electrical measures stated above. However, it could also be running a pump in which case the output of the pump would be gallons per hour or something similar. The basic measure can also be looked at as pounds per square inch of force provided by the wind on the x sail area of the device. This theoretical maximum would be used for calculating the efficiency of any resulting work.
there are are three ways. amps, watts, and volts.

I would attach a watt meter to the generator, assuming it is a working windmill.
