KIBI, Wakayama Pref. -- On top of a 586-meter-high mountain here, white blades of a wind turbine rotate in the strong wind.

The 51-meter-tall power system at Washigamine Cosmos Park is the largest wind power generator in the Kansai region. It began operating in mid-May, and generates 230 kw per hour.

As the central government prepares a bill to promote the use of clean energy, municipalities in the region are moving ahead with their own plans to introduce wind power generation and other clean energy systems.
