Small vertical wind turbines have been used to generate power from the wind created by highway traffic. The turbines are located near the roadway in rows on divided highways, or in clusters between opposing lanes - see image: (twitter.com/MikeHudema) or singly: Generation of electricity on highways by VAWT (vertical axis wind turbine) (youtu.be/du0lYubtlfQ). Enough energy to run many homes can be produced - steadily, dependent on traffic more than the weather.
Small wind turbines have also been attached to light poles and are being used increasingly in green energy design. They can be attached near or on buildings as they are small in diameter.
