    The main issue is the small size tends to increase the required wind speed required to initially overcome friction, and those higher windspeeds are rarely sustained at ground level. Large turbines work efficiently because they are up above the turbulence caused by houses, trees, buildings, etc.

    I don’t save links to everything I ever read, so you’ll have to search it up if you’re curious for more details.

      Really depends on where you live. If you’re in suburbs they’re completely fucking useless. If you’re in the country with over a mile of relatively flat fields upwind it’ll work, especially if you already have an old antenna tower or can put one up.

      Also, the larger commercial tirbines are trying to generate commercial levels of power, not residential. And for a given wind speed the power generation scales by blade length, and a lot of that height is also needed as clearance for the blades
