A kilowatt is an instantaneous measure of power. At any moment, the power that is produced by a small wind turbine is measured in watts or kilowatts (1000 watts). A kilowatt-hour is a measure of energy production: how much energy is produced over one hour. For example, if you turn on a 60W (.06 kW) light bulb for one hour, you draw .06 kWh. If you keep it on for a full year, you will use .06 kW x 8766 hours = 526 kWh. Of course, you should never do this!
