American companies are being squeezed out of the lucrative Chinese wind-power market at the same time as Dallas-based investors are bringing Chinese firms to the US via a big wind farm project in Texas, according to a new industry report. PES examines a potentially-damaging situation.The study examines Chinese government policies promoting the development of industries producing equipment for generating electric power from renewable energy sources (hydro, wind, biomass, solar) to serve electrical grids. Those policies are transforming China into a major production base for renewable energy equipment at the watershed moment at which total global investments in renewable energy power capacity have surpassed investment in fossil fuel power capacity, the report claims. China's rapid economic growth and urbanization has been paralleled by rising energy consumption with the country now second only to the US in total primary energy consumption.It has also emerged as a larger generator of energy-generated CO2 emissions than the US and it faces a dilemma in that its indigenous reserves of oil and natural gas will be depleted within two decades at current rates of extraction, and coal, which accounts for about 75 per cent of China's energy production, is a source of pollution and greenhouse gas

Wind turbines are on the up. The giant constructions are constantly getting taller because, as every schoolboy knows, the higher you get off the ground, the greater the wind speeds. But building big towers is a costly business, especially if you want one 15,000ft tall. So why not ditch the tower and make the windmill fly? PES investigates one possible future for energy generation

SIMPACK AG offers general purpose three dimensional Multi-Body Simulation Software which is uniquely suited to the analysis and design of any type of wind turbine design. Built upon well-proven technology used in other application areas - such as the gear wheel element developed for the Formula 1 racing industry - the company delivers a pre-eminent insight into the dynamics of wind turbine systems. We spoke to Steven Mulski, Director Wind Energy Solutions.PES: Welcome to PES magazine. Can you tell us a little about the history of your company and how it serves the wind industry?Steven Mulski: The history of SIMPACK AG started in the late 1980s with a cooperation between the German Aerospace Centre (DLR) and MAN Technologies. At the time there was no suitable general non-linear Multi-Body Simulation (MBS) code on the market which could import flexible bodies from Finite Element (FE) codes, required for analysing higher frequency dynamics.The DLR's involvement with MBS codes goes back into the 1960s. MAN technologies was involved in many different industrial sectors, from railway and road vehicles to aerospace and wind turbines (Growian and Aeroman) applications, and recognized the need for a completely new type of simulation code, thus SIMPACK was born.

The Tin Man in the Wizard of Oz fretted over his joints, and owners of wind turbines have the same angst. They need to be assembled offshore and maintenance of the joints is critical where a 20+ year life expectancy under the buffeting of winter seas and gusting storms is normal. The assembly is subject to prying forces, vibration and continuous temperature variation in a highly corrosive atmosphere of salt spray, rain and UV. Intellifast presents an illuminating despatch from the frontline of the wind energy arena

Gulf Stream Marine commands attention for its innovations and flexibility. Now more than ever, both help the company maintain its position as a leader in the specialized field of wind turbine transportation. Company CEO, Jan Rietdijk, explains …PES: PES first caught up with Gulf Stream Marine last year. What is new with the company?Jan Rietdijk: The principles of our business are the same – offer quality customer service, flexibility and a commitment to innovation. What has changed over time is the amount of business we do in the handling of wind turbine components. Although the total amount of wind business is down in the Gulf Coast region as a result of the economic recession, it is still a very large part of our business at three of the seven terminals that we operate in this geographic area. PES: What do you mean by a “commitment to innovation?”JR: We never stop asking how we can improve our business operations. Our work in the wind industry provides a perfect example. We engineered custom equipment and performance operations to make us uniquely qualified to handle this type of cargo. We began with a vision centred on a fundamental question: “How can we handle this

French fur traders first visited Nebraska in the 17th Century and the state was later explored by pioneers Lewis and Clark from 1804-1806. A few years later, Robert Stuart pioneered the Oregon Trail across Nebraska in 1812-1813 and the first permanent white settlement was established at Bellevue in 1823. Now a new report says Nebraska could obtain 40 per cent of its electricity from wind energy. PES examines the report and finds the new LB1048 legislation could help put the state at the vanguard of the US wind generation business

As Vice President of Industrial Products Sales for BNSF Railway, Katie Farmer has witnessed railroad's evolution into a 21st century transport provider for 21st century industries such as wind power. PES talks to Katie about the company's growing influence and its ‘total transportation package'.PES: Welcome to PES magazine. Can you explain a little about your company and outline the services you provide for the wind industry?Katie Farmer: BNSF Railway is a freight railroad company that plays a key role in the global supply chain. We operate along a network of more than 32,000 route miles in 28 states and two Canadian provinces. But broader than that, we serve as a transportation provider for many commodities that are imported and exported through our US ports. Our focus is on using speed, agility and resourcefulness to help expand the global marketplace for goods and services.All of this is accomplished by a team of individuals who are progressive, resourceful and approachable. We take great pride in providing an easy, relevant choice for all types of shippers in a wide variety of locations.We're committed to meeting the needs of this emerging market. We realize that transporting oversized wind turbine components from the factories or

The solution to offshore wind energy obstacles lies in pooling all the power into one common electricity grid, according to researchers at the University of Delaware and Stony Brook University. "We hypothesize that wind power output could be stabilized if wind generators were located in a meteorologically designed configuration and electrically connected," say the authors of the report "Electric power from offshore wind via synoptic-scale interconnection." It's a brave hypothesis, one that reflects the efforts being made over the Atlantic with the European Supergrid. PES presents the research
