The amount of electrical energy generated by a windmill / turbine generator will vary quite a bit depending on the size of the blades as well as the wind speed.
Some small turbines might only produce a few watts of power while other, larger, turbines might produce thousands of watts (kilowatts) of power. It largely depends on the turbine and its location.

As the sun heats up the Earth unevenly, winds are formed. The kinetic energy in the wind can be used to run wind turbines, some capable of producing 5 MW of power. The power output is a function of the cube of the wind speed, so such turbines generally require a wind in the range 5.5 m/s (20 km/h), and in practice relatively few land areas have significant prevailing winds. Luckily, offshore or at high altitudes, the winds are much more constant.

Ke = (mv^2)/2
The energy generated by a windmill is most easily modelled by the equation for kinetic energy. The heavier and faster the windmill spins, the more energy it generates. Plain and simple. Just like physics should be.
(assuming 100% mechanical efficiency).

It depends on the wind speed, the number of blades, their pitch, the diameter of the blades. A large one will put out the kilowatts. And it is free power. You can always put up multiple windmills. But in my state there is not enough wind to economically justify it.

It probably depends on the size/type of the windmill and the strength of the wind blowing it.

So, how big is the windmill, what are the characteristics of the prevailing wind and other details are needed.

The typical commercial windmill for electric generation is one mega-watt. The largest so far in N. America is in Toronto. It will generate 1.8 mega-watts.

there are many different types of windmills on the market, from as little as 30amps to 200 amps. the bigger the more electricity generated

just a little less than what is needed to run a windmill

The alternator on your vehicle is more beneficial effective than those windmills. you may want to even if positioned photo voltaic cells on the roof of your vehicle. that couldn't impression the speed of the vehicle a lot.
