I can't afford it this year, but I am seriously considering putting a windmill on my property to generate some electricity, as well as getting some solar panels.
Personal Windmill Info:
Costs Not Included - Installation equipment, Install/Erection.
Size: 33 Feet, >600 lbs.
Average Monthly Energy Production: 500 to 700 kilowatt-hours
Average Monthly Energy Consumption (household): 1,000 kWh
Payback (at current energy prices): 5-10 years.
General Info: The turbine’s blades begin turning once winds reach a speed of 6 mph, and an inverter inside the turbine begins generating energy when wind is blowing at 8-10 mph. At wind speeds of 20 mph, the turbine reaches its maximum output.
Comment from someone who's installed one:
Residents who are interested in one must first obtain permission from a local zoning board...
there are no codes in place regarding wind turbines, since they are a relatively new phenomenon, Broadt explained. And officials are wary about setting a precedent that could open the door for larger-scale, commercial wind farms, he said.
The Skystream 3.7 turbine sits about 190 feet from Broadt’s house on his one-acre property. The company recommends that turbine owners have at least half an acre of land.
