Wind turbines to be made of tougher stuff

Power-generating wind turbines will soon have to comply with tough new technical standards to ensure they can withstand typhoons, lightning strikes and other extreme weather conditions. Wind-power generation is a major pillar in the government's push to use alternative energy sources to fight global warming. In recent years, however, storms have caused extensive damage to many wind turbines. International standards drawn up in Europe are not sufficient to protect wind turbines from Japan's weather patterns, according to officials of the Nuclear and Industrial Safety Agency, an arm of the Ministry of Economy, Trade and Industry.

Wind turbine topples over: Question is why?

HIGASHIDORI, Aomori Prefecture–The industry ministry Wednesday said it is trying to determine what caused a 68-meter-high wind turbine to collapse earlier this week since strong winds apparently were not blowing at the time. The incident at the Iwaya Wind Farm in the Iwaya district of Higashidori in this northern prefecture is thought to have occurred late Monday, according to officials of Eurus Energy Holdings Corp., which manages the wind farm. While no one was injured, the incident resulted in temporary power outages to homes in the area because power lines were severed.
