There are wind turbines for the home garden, but they are not very effective - as far as I have informed myself. Since I am not very knowledgeable about this topic, I would like to link you a free calculation program from the Fraunhofer Institute for Wind Energy and Energy System Technology; example: If a system with a diameter of one meter is installed at a height of six meters in a rural area, then at an average wind speed of three meters per second, 38 kilowatt hours of electricity can be expected annually. Enter realistic wind speeds, and you can calculate how much electricity the planned wind turbine would produce.
