What capacity wind turbine should I buy if my monthly consumption is 1000Kwh for my residence?

If I bought a 400w wind turbine how much would that off set my electric bills? I live in a high wind area, say I have 20-30mph winds once a week with 13-17mph 3 times a week. I watch TV, the computer, and use the water pump, fridge and stove regularly...

my leccy bill is very expensive, someone suggested i install a wind turbine, would i need planning permission

for a one year period,if both were equally optimised,then how many typical single family homes's could be powered?how do you figure out how much physical space do each or both require,if the turbine has 80' blade's and is mounted on a 140m tower?

I am looking for a wind turbine to add to my off grid solar system. I looking for a 50 or 100 watt system. Where I live I don't a lot of wind so wind turbine must be very efficient. I am not sure what the best option would be build my own or buy one...
