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 ...

The construction of a windcatcher depends on the prevailing wind direction at that specific location: if the wind tends to blow from only one side, it may have only one opening, and no internal partitions. [2] In areas with more variable wind directions, there may also be radial internal walls, which divide the windtower into vertical sections.

In 2004 Iran generated only 25 megawatts from wind power, 32 megawatts in 2005, and 45 megawatts in 2006. By 2009, total wind power capacity reached 130 megawatts. This was a result of the production of larger wind farms in more coastal and windy areas of Iran, such as Manjeel (Gilan province) and Binaloud (Razavi Khorasan Province).
