The technology is expensive, but Vermonters involved in the project say there's good reason to move ahead with it.

The deal, which is still subject to final approval, will see Vestas take control of the rights to OCAS's system to prevent aerial collisions. The system is approved by aviation authorities in countries including Sweden, the US, Norway and Canada.

Danish wind turbine manufacturer Vestas Wind Systems AS is developing a new offshore wind turbine model following recent gear box problems at several of its currently operating turbines, Swedish magazine Ny Teknik said. ...Peter Wenzel Kruse said gear boxes are a problem for the entire wind power industry, because strains on the boxes increase as ever bigger windmills are built.

A major blade manufacturing plant in east Windsor appears to be only a starting point for global wind-power giant Vestas Wind Systems. The company, based out of Denmark, announced Thursday that it now has intentions to build a research and development center in the United States. "Today, Vestas is a technology enterprise. If we want to be market leaders, we have to be present and drive the development, where the market is. And that is, amongst other places, in the U.S.," said Finn Strom Madsen, president of Vestas Technology R&D in a press release. The center is expected to be operating in 2009 and could employ up to 80 people at full capacity in 2010.

Shares in Vestas, the world's largest wind turbine manufacturer, plunged almost 14 per cent on Thursday as the Danish company downgraded its full-year forecast because of a severe shortage of key components, a sluggish output rate and budget overshoots in the US market.

Around 20GW of planned wind farms globally face objections from air traffic controllers because turbines interfere with radars near military bases or airports. Turbines can reflect radar waves, appearing on radar screens as 'clutter' in an unpredictable and confusing way.

COPENHAGEN - Denmark's Vestas Wind Systems said on Tuesday it had won its biggest order in the United States with a contract with Horizon Wind Energy, sending its shares higher.

FINANCIAL TIMES: There has been some recent legislation on Co2 reduction. I wonder if you see that as one of the big developments of late, and what its significance is.

JEFFREY IMMELT: Yes. I think if you look at what some of the states are doing, California for instance, or even what's happening around the world, what's talked about in the UK, I think that's going to change the way people look at technology and it's going to change the way people look at energy policy in the future. It tends to be the way change starts. I would say in many ways some of the things that have happened in Europe over time have tended to drive technology. For instance, when Europe said it was going to have 10 per cent renewables that's what really opened up the world of wind energy and solar and things like that, so I think it's very meaningful.
