yes, but if i cannot afford a million dollars for a large one, i may be able to afford 10k to put on on my acreage, or 2k to put one on my house.
Many power companes are now required to allow net metering, which makes the cost of micro wind generation lower since no batteries are required.
For many of us, it’s an awesome option. While it’s not as efficient, it’s better than the nothing we can afford if large scale is the only other option.
Vertical axis wind …
Vertical axis wind turbines (VAWT) are just as efficient as horizontal wind turbines with aerodynamic performance coefficients up to 0.45, investigated by the DOE at Sandia Laboratories. Both horizontal and vertical turbines use aerodynamic lift to propel the turbine, just the rotation is in a different axis. Performance accounts for the torques imposed on the rotor so the sizes of the blades are unjustified. VAWTs are typically quieter, require less material to build and are equally efficient.
