A generator (doesn't matter if its a water turbine, solar, diesel, or wind) will have a plate stating its capacity in watts. A 1000 watt generator operating at a steady capacity for one hour would produce 1000 watt hours, which is the same as 1 kilowatt hour. In 10 hours it would produce 10 kilowatt hours.
But finding the right size generator is much more complex than that as you need to consider entropy, line loss, load variations, and especially wind variations.
The average house in North America consumes about 20-25 kilowatt hours per day. The difficult challenge is that most houses consume power at highly variable rates, wind is not always at the same speed, and air is not always at the same density. Therefore it will be almost impossible to have a wind turbine to guarantee you the right amount of electricity on demand at a given time.
That's why power utilities like to use wind turbines as a supplement to a more reliable source to provide base load capacity such as hydro. If there's lots of wind, they can use the wind energy to supply electricity, and close the dams to store water for energy needed when there is no wind. The bottom line is that solar and wind are simply not capable of producing constant base load power, which will therefore continue to be provided by hydro, coal, or nuclear.
