Small wind is horrible, the efficiency of wind is entirely based on the swept area of the blades. At scale it’s great, but at household sizes it’s just not worth the cost. Turbines and windmills are a ‘Go big, or go home’ situation as far as being cost effective. Solar, even with batteries, is more cost effective for household or mobile sizes.

There are some interesting new technologies hitting the market. They use vibration to extract energy, rather than rotation. This is a lot more efficient at small scales. While they are extremely situation specific, they can outperform solar for some areas, particularly in winter.
