A German company has designed and developed an innovative hub for wind turbines, made entirely from composite structures and is approximately 50 percent lighter than comparative steel components. This particular composite hub is capable of withstanding external wind loadings in addition to the forces enacted upon it during wind turbine operation.

The advent of energy production with the use of wind turbines has resulted in a great many of these giant sized rotary devices strewing the country-side. Whilst their contribution to energy production is both green and renewable, there has been some concern about the impact their physical presence has made on the aesthetics of the environment. As a result, an EC funded project has investigated alternative locations for wind turbines., , Image Copyright; © Project WEB Institut für Baukonstruktion und Entwerfen, L2, Universität Stuttgart
Worldwide, the wind energy sector has now become firmly installed as one of the important players in the energy markets, with the total value of new generating equipment installed in 2006 reaching €18 billion, or US$23 billion from US$14 billion in 2005.

The above table pattern of development shows that new players such as Portugal and China are gaining ground.
What could be the reason?
Some facts from China:
According to a a reported invterview, Vestas Chief Executive Officer Ditlev Engel played down the market share drop, saying an additional $750 million of projects expected to come online in the first half of 2008 would help to counteract the slip. “We’ve been surprised by how fast new entrants have entered the market. Yet since 2006, we have invested more than €1 billion ($1.5 billion) in organic growth,” he says.
The main challenge has come in China where local firms, such as Sinovel and Goldwind, have taken advantage of a Chinese government push to increase renewable generation from 7% of total energy production to 15% by 2020. That has led to an explosion of activity from both local and international players, such as General Electric (GE) and Siemens (SI). Vestas, for example, increased the number of wind farms delivered to Chinese clients by 20% last year, compared to 2006. But Chinese firms have increased their local orders, taking a bite out of Vestas’ share of the market.
Despite the slip, analysts reacted favorably to the Danish company’s results, which included a 26% increase in annual revenues, to $7.3 billion, and operating margins that grew almost four percentage points year-over-year, to 9.1% in 2007. According to forecasts from Vestas, revenue should hit $8.5 billion in 2008, while operating profit is expected to increase 10% to 12% by year end.
