A vertical-axis wind turbine (VAWT) is a type of wind turbine where the main rotor shaft is set transverse to the wind while the main components are located at the base of the turbine. This arrangement allows the generator and gearbox to be located close to the ground, facilitating service and repair.
The company was founded in 1998, and released their first patented vertical axis wind turbines in May 2006. [1] [2] In 2007, they added another two models of turbines to their product lineup. [3] In November 2008, certain intellectual property assets of PacWind were acquired by WePOWER, LLC.
A panemone windmill is a type of vertical-axis wind turbine. It has a rotating axis positioned vertically, while the wind-catching blades move parallel to the wind. By contrast, the shaft of a horizontal-axis wind turbine (HAWT) points into the wind while its blades move at right-angles to the wind's thrust. It is a rudimentary and inefficient ...

In 2005, the company (then called Zilkha Renewable Energy, and owned by Selim Zilkha and Michael Zilkha) was purchased by investment bank Goldman Sachs for an undisclosed sum and renamed Horizon Wind Energy. In 2007, the company was acquired by Energias de Portugal for $2.15 billion [1] and later renamed EDP Renewables North America. [2]
Savonius wind turbines are a type of vertical-axis wind turbine (VAWT), used for converting the force of the wind into torque on a rotating shaft. The turbine consists of a number of aerofoils, usually—but not always—vertically mounted on a rotating shaft or framework, either ground stationed or tethered in airborne systems .
Fig. 1: A Darrieus wind turbine once used to generate electricity on the Magdalen Islands. The Darrieus wind turbine is a type of vertical axis wind turbine (VAWT) used to generate electricity from wind energy. The turbine consists of a number of curved aerofoil blades mounted on a rotating shaft or framework.
