Windmill in your backyard for $8500
Available in 35-110 foot heights (determined by your site characteristics), this slim yet high-performance wind generator can produce 400 kilowatts of energy per month, up to 90% of an average household’s energy consumption. Skystream works efficiently with your local utility grid, too, switching back to grid power when wind speeds drop below 8 miles per hour. So what’s the fine print? Skystream, while intended for residential use, requires roughly an acre of land to function properly, and costs $8500 including installation of the 35-foot tower. Southwest Windpower estimates the wind tower paying for itself in four to twelve years, depending on your energy consumption and local utility rates.

Just a clarification here in terms of units (and this is important in order for what you’re saying to make sense): “wind generator can produce 400 kilowatts of energy per month” makes no sense, since kilowatts, as a unit, is not based on time. A lightbulb uses some number of kilowatts (0.1 for a 100 watt lightbulb), but you would never describe its power use in kilowatts or watts per month. You could, however, describe how many kilowatt-hours a lightbulb uses or a windmill generates in a month. That makes sense because it includes the unit of time.
