Aug 07, 2017 · Verticalaxis wind turbines, although output is lower and a lower height means wind speeds are generally lower, offer easier access to mechanical parts. Wind from any direction moves the turbine and the vertical axis enables the blades, spinning horizontally to the ground, to move when the wind blows from any direction.

In 1931 the Darrieus wind turbine was invented, with its vertical axis providing a different mix of design tradeoffs from the conventional horizontalaxis wind turbine. The vertical orientation accepts wind from any direction with no need for adjustments, and the heavy generator and gearbox equipment can rest on the ground instead of atop a tower.
