Union Pacific operates North America's premier railroad franchise, covering 23 states in the western two-thirds of the United States. PES spoke to Byron Willis and Beth Whited to ask just what that means for the transportation of freight for the wind industry.  What are the points of differentiation for Union Pacific compared to other railroads as a wind component hauler{pagebreak}Byron Willis: A growing network of wind distribution centers, a fully integrated logistics solution through Union Pacific Distribution Services, the right equipment and the greenest locomotive fleet in the industry allow Union Pacific to serve wind energy customers like no other transportation company. We were the first railroad to offer door-to-door rail transportation solutions for moving wind turbine components. We are on the Web at www.up.com/wind.PES: What are your advantages compared to over-the-road trucks? Beth Whited: Union Pacific offers several advantages: •Rail is considerably less expensive due to our ability to simplify logistics and achieve economies of scale • We own our tracks so we do not require the state-by-state permitting necessary for trucks • We operate in a more controlled and safer environment • Trucks add to highway congestion; it takes considerably more trucks to deliver the same number of wind turbines

New Federal tax incentives established by the ARRA for financing wind projects [sell] The American Recovery and Reinvestment Act of 2009 (ARRA) added two new and significant provisions, enacted as part of an effort to spur domestic development and installation of renewable energy, that are available to developers to help finance their wind projects.{pagebreak}The first provision of the ARRA permits the wide-range of renewable energy facilities that qualify for the federal production tax credit (PTC) under Section 45 of the Internal Revenue Code, including those powered by wind energy, to claim the federal investment tax credit (ITC) under Section 48 of the Code in lieu of the PTC. While the PTC is based on the amount of electricity produced and sold to an unrelated person during the 10-year period beginning on the date the facility is placed in service (currently at the rate of 2.1¢ per kWh of such electricity for wind), the ITC is a one-time credit claimed in the year the facility is placed in service that is generally equal to 30 per cent of the cost of the renewable energy facility.The second provision created a new program that enables PTC-eligible and ITC-eligible facilities to receive a

The global energy marketplace remains increasingly competitive and customers are striving hard to increase their productivity. Considering this pressure, they are continuing to seek out innovative means to reduce energy consumption as one method to remain competitive.{pagebreak}To satisfy this demand Mobil Industrial Lubricants is clearly identifying those lubricants of its portfolio that demonstrate measurable energy efficiency benefits. Take Mobil SHC 524 for example, our high performance synthetic hydraulic oil for critical wind turbine applications such as the pitch control of rotor blades.   Increased hydraulic efficiency means greater productivityThe additive and base oil selection of a lubricant can have a significant impact on its traction coefficient. Mobil SHC 500 series has a significantly lower traction coefficient compared to a mineral oil based product which translates to lower internal fluid friction and can mean less energy consumption.         caption: Mobil SHC 524 has a significantly lower traction coefficient and maintains better oil film protection under high pressure and temperature

Intellifast GmbH is a leading name in the ultrasonic load measurement business, launching on to the market in 1997 with a focus on the world biggest bolt consumers – the car industry. Here, Managing Director Frank Scheuch talks to PES about the company, its expansion into the wind industry, and his vision for its future.Intellifast was founded as PFW Technologies in 2002.{pagebreak} The company changed its name to Intellifast when it acquired the Intelligent Fastener trademark in 2006 and when its sister company, PFW GmbH changed its name to PFW Aerospace AG. The business was started with the acquisition of an ultrasonic load measurement technology, invented in 1993 and launching into the market in 1997 with a focus on the world biggest bolt consumers - the automobile industry. the central technology is a thin film permanently mounted transducer. Using high- vacuum technology, the thin film transducer is deposited on to the bolt. The materials used are immune to the elements and are inert to their environment. To read the bolt load, the transducers are connected to an ultrasonic measurement device. The measurement of the clamp load is accurate to +/- 3 %. The patented digifast barcode technology provides ultrasonic fastener information on each

TradeWind – the European project funded under the EU’s Intelligent Energy-Europe programme – has recently published an essential 100-page paper on the state of the European wind power industry. In this exclusive extract from the comprehensive, hard-hitting report, PES picks out all the important and salient issues facing us all as we move into an uncertain future.{pagebreak}Nevertheless, the good news is that the report concludes that the recent rapid growth in wind power generation – triggered by technological and industrial development and the move towards sustainable economics – indicates that wind power should be seen as one of the main domestic sources for electricity generation within the European Union.  IntroductionEurope’s dependency on imported fossil fuel has become a threat to economic stability, increasing uncertainties over energy prices. At the same time, the European electricity industry is facing a huge challenge related to generation capacity investment needed in the coming years. The surplus capacity that existed in some countries prior to liberalisation is diminishing and many existing power plants are getting closer to decommissioning. For these reasons, one of the key points on the European energy policy agenda is to increase the share of demand covered from renewable energy sources. European

pes presents half a dozen lessons, which if heeded in future offshore projects, together with the other parts of the offshore wind ecosystem, we can make for smoother, quicker, and cheaper installations and ultimately, better windfarms for the production of clean energy.{pagebreak}Over the years we have all heard much about the potential of offshore wind as an energy source. Now, in 2009, the industry has finally reached a position to begin realising much of that potential. The projections for offshore wind are staggering: currently there are plans for almost 40GW of offshore wind energy in the UK, and as is well known, Denmark and the UK currently lead the world in installed offshore capacity.  In Germany, where the first offshore windfarm is expected to be powering German homes and communities by the end of this year, the expectation is that by 2030, 15% of German electricity consumption will come from offshore wind. Around the North Sea, many countries have set similar targets for themselves; the European Wind Energy Association has a projected target of 40GW offshore by 2020. These are huge, challenging goals that recognise the potential of offshore wind as a key part of any attempt to move away

The Times of London has just published its first green global rich list, with many tycoons and executives from the wind industry making the top 100, including the USA’s Warren Buffett who tops the poll at number one, being worth a cool Euro 37bn. Here, PES presents your handy guide to the top 10 movers and shakers in the wind power industry.{pagebreak}The list shows the true degree of enthusiasm among the world’s wealthy for investments in areas like electric cars, solar power, geothermal and wind power. It was restricted to 100 businessmen and women or families whose accumulated wealth amounted to £200m or more and who had made either serious investments in green technology and businesses or a substantial financial commitment to environmental causes. What the newspaper’s impressive list demonstrates definitively is the fact that many of the world’s richest and most powerful entrepreneurs are now embracing environmentalism in a fulsome, wholehearted manner, which could only have been dreamed of a decade ago. To put all this into some perspective, Warren Buffett (worth Euro 37bn) is now regularly swapping places with the rather more high-profile Bill Gates (worth Euro 30bn) at the top of Forbes magazine’s annual list of world

During the past decade it has become extremely important to optimise all aspects of product design. Competition is tougher than ever and steel costs have skyrocketed. For economic reasons each component must be utilised to its maximum capacity. Bolted joints became the centre of attention after recent findings that they are often used to as little as 30 per cent of their capacity.{pagebreak} Moreover, a failed critical bolted joint could lead to expensive warranty claims or maintenance costs. Control of the clamp load in a bolted joint is vital. However, when faced with a problem joint, it is not surprising that the design engineer will not have an answer if asked about the clamp load. Torque calculations must always be based on the existing conditions that often are very vague. Unless all parameters are correct, the calculation will be unreliable. Examples of parameters are:            Thread condition of the fastenersHardness of contact surfaceMaterial (steel, aluminium, copper, etc.)Extra friction from a locking fastenerExtra friction from an adhesiveLubricant on the threadType

Considerable wind resources place many countries across the region in an enviable position. Yet capitalising on those resources can prove problematic, due to local planning restrictions. This case study from the UK highlights the problems faced and offers a number of solutions that will resonate with wind energy suppliers throughout Europe.{pagebreak}The UK has enviable wind resources and the potential to become the green powerhouse of Europe, yet lags behind many of its neighbours in its use and development of renewable energy from wind projects. Ambitious targets have been set by the UK Government, which equate to 30% of electricity from renewable energy resources by 2020. Currently however, less than five percent  of electricity comes from renewables, highlighting the major challenges ahead to meet these targets in the next ten years. A number of issues surround the UK’s delay in exploiting its wind energy resources. However, the complex planning systems which are in place have been identified by both the Government and developers as the major obstacle to progress.There are many examples of the planning system failing the renewable, and traditional, energy industry in the UK. The Ray Wind Farm proposal in Northumberland, for example, was the subject of application to
