4 April the transfer of remaining copies of Wind Energy for the Rest of Us to a new distributor was completed. The poor outlook for books on wind energy in English has led Chelsea Green to exercise its right to cancel its contract to distribute Paul Gipes latest tome on wind energy. Distribution rights and all remaining print copies have been transferred to BCH Fulfillment & Distribution. The books are safely in BCHs warehouse and BCH has begun shipping books. The transfer has been seamless. BCH does not distribute ebooks. Distribution of the ebook version has not been completed. Consequently, there may be a short hiatus on the availability of the ebook until a new distribution channel is created. Wind Energy for the Rest of Us was ranked fifth by sales on Amazon in 2017 for books about wind energy. It was behind books like Wind Power for Dummies, Build Your Own Small Wind Power System, and Homebrew Wind Power, but ahead of more advanced engineering treatises. Chelsea Green has published and ...

Background: Wind turbines are a form of renewable energy, which generate electricity from wind energy, a practice dating back over 100 years. More recently, large-scale wind energy developments have started to employ one or several industrial wind turbines, which produce the majority of wind energy in Ontario. The production of electricity from the movement of industrial wind turbine motor blades creates both mechanical and aerodynamic noise. This type of environmental noise is a growing public health concern, especially for residents living close to industrial wind turbines. A body of evidence now exists to suggest that industrial wind turbine noise can impair health and contribute to annoyance and sleep disturbance. However, in Ontario, little is known about how industrial wind turbines impact people living in their vicinity. Objectives: This investigation was a cross-sectional study involving eight Ontario communities that contain greater than ten industrial wind turbines. The objectives of ...
With a rapid growth in the renewable energy projects over the past few years, the total installed capacity of the wind power plants across the world has witnessed a manifold increase. Advancements in wind turbines designs have also led a surge in the installed capacity of wind power.. Many companies have developed wind turbines that can produce power in low wind areas with reduced costs. With a scope for development of wind farms even in offshore locations, the electricity generation from wind has been on an uptrend in many countries in recent years. Further, wind power installations occupy less space compared other modes of power generation, bringing in increased operational efficiencies. Wind farms can also be built on agricultural lands, without causing any interruption to cultivation activities.. In its Global Wind Report: Annual Market Update report, the Global Wind Energy Council (GWEC) said that cumulative global wind power capacity grew by 12.6% to reach a total of 486.8 GW in 2016. The ...
Introduction. Climate change and fossil fuel depletion have pushed many countries to seek and invest in alternative clean energy sources, such as wind energy. By converting kinetic energy from the wind into mechanical or electrical energy, wind farms in California, for example, power nearly 850,000 households each year, while producing negligible green house gases and contributing little to water pollution.[1] Nevertheless, several ecological and environmental concerns remain. High levels of infrasound and low frequency sounds generated by wind turbines pose a potentially serious threat to communities near wind farms. Wind energy companies remain largely dismissive, claiming that wind turbine noise is subaudible, undetectable by humans, and therefore presents minimal risk to human health. However, various cochlear microphonic, distortion product otoacoustic emission, and fMRI studies have demonstrated the detection of infrasound by the human inner ear and auditory cortex. Additional ...
Since the end of 1990s the growth of new energy and renewable energy production has been strong and increasing. Wind power energy has become one important source of energy almost all over the world. Europe, USA and Asia has become the leading markets in the development of wind energy. The total volume of global wind energy production has increased from 13,600 MW in 1999 to 318,137 MW in 2013. Since 2006 the wind energy industry is showing very rapid growth as well as dynamics among major industry actors. Some companies has left the industry due to heavy competion, some has used the growth as an opportunity to expand and the inceasing demand and the growth in the wind energy sector has opened opportunities for new actors to enter the industry. China has very fast become the largest country in the world in terms of installed wind energy capacity (28,7% share of total installed capacity and 45,4 % share of installed capacity in 2013). China is followed by Germany, UK and India. USA is now on the ...
Denmark and Indonesia have signed an agreement to promote and expand renewable energy infrastructure in the south-east Asian country. According to media reports, the two countries signed an agreement to set up a 60 MW wind energy project in the South Sulawesi province; the project will be the first wind energy project in the province. Indonesias power company will work with a Danish consortium led by Equis to set up the project. Another Danish company, Vestas Wind Systems, has also agreed to supply wind turbines and other equipment for the project. "We are delighted to sign this agreement and continue the work to finalize the project. Vestas sees a long-term potential for wind energy in Indonesia, and we are confident this project can help pave the way for additional wind power investments," Vestas chief executive Anders Runevad said.. In April this year, US-based Overseas Private Investment Corporation (OPIC) agreed to provide debt to the largest wind energy project in the country. OPIC ...

In 2007, the FAST wind turbine simulation tool, developed and maintained by the U.S. Department of Energys (DOEs) National Renewable Energy Laboratory (NREL), was expanded to include capabilities that are suitable for modeling floating offshore wind turbines. In an effort to validate FAST and other offshore wind energy modeling tools, DOE funded the DeepCwind project that tested three prototype floating wind turbines at 1/50th scale in a wave basin, including a semisubmersible, a tension-leg platform, and a spar buoy. This paper describes the use of the results of the spar wave basin tests to calibrate and validate the FAST offshore floating simulation tool, and presents some initial results of simulated dynamic responses of the spar to several combinations of wind and sea states.
Since a wind turbine generates electricity from the energy in the wind, the wind leaving the turbine must have a lower energy content than the wind arriving in front of the turbine.. This follows directly from the fact that energy can neither be created nor consumed. If this sounds confusing, take a look at the definition of energy in the Reference Manual. A wind turbine will always cast a wind shade in the downwind direction. In fact, there will be a wake behind the turbine, i.e. a long trail of wind which is quite turbulent and slowed down, when compared to the wind arriving in front of the turbine. (The expression wake is obviously derived from the wake behind a ship). You can actually see the wake trailing behind a wind turbine, if you add smoke to the air passing through the turbine, as was done in the picture. (This particular turbine was designed to rotate in a counterclockwise direction which is somewhat unusual for modern wind turbines). Wind turbines in parks are usually spaced at ...
Wind Resources. (7.5 credits, Spring18/19, weeks 04-12, 50%.). In this course the concept of wind energy and the different methods that are used for wind resource assessment will be explored. Further, the factors having an influence on the wind and what they mean when assessing the wind resource at a site will be studied. Wind energy calculation methods, including how they model the wind to calculate the energy production of a wind turbine will be investigated. Different wind measurement methods and their aims of evaluating the wind conditions at a site for wind power projects are also explored.
Renewable energy wind turbines as electricity sources possess extreme environmental problems not found in their renewable energy rival-solar photovoltaic. These problems are due to rotation of 130-foot or more long, thirteen-ton turbine blades with tip speeds of 200 miles per hour. "An unavoidable problem of wind turbines is killing flying creatures. The Committee For A Constructive Tomorrow (CFACT) produced a video "Eagle lawsuit ruffles wind industry feathers". The video records a bird apparently being killed by a wind turbine. It appears the bird went back for a second look at the turbine and a blade struck the fatal blow. Possibly the bird thought the turbine was a bigger bird.". A companion article published March 19, 2013, by CFACT is "Wind turbines kill up to 39 million birds a year" by wildlife expert Jim Wiegand. Details of studies on bird fatalities caused by wind turbines are cited in this article. The source of Jim Wiegands statement wind turbines kills up to 39 million birds a year ...
That didnt happen. They havent even started working on it.. The thing is, Kenya could really use this wind power. The whole continent could use wind power, but beyond South Africa, there arent a whole lot of projects in the works.. Check this out: when the Global Wind Energy Council [PDF] breaks down wind power by region, it doesnt even give Africa its own line, so minuscule is the total. Instead, Africa gets lumped in with the Middle East. And even at that, the total is a mere 1,093 megawatts (MW) out of a 238,351 MW of global wind capacity as of the end of 2011 - and more than half of that was in Egypt!. The director of the Lake Turkana Wind Power Project, Chris Staubo, told AFP recently that when (when) it comes online, the wind farm will represent 20 percent of Kenyas electricity production.. The holdup on the project is the financing, which, always complex to begin with on projects like this, is even hairier because the wind farm isnt the only thing that needs to be built.. The ...
CLINTON - Opposing sides for a proposed wind farm in DeWitt County say they are prepared for up to 35 hours of scheduled meetings before the Zoning Board of Appeals, beginning Tuesday night at Clinton High School.. "Its going to be a long month," said Andrea Rhoades, a rural DeWitt County resident who opposes the project.. Tradewind Energy has applied for a special use permit to develop a $300 million wind farm in northwestern DeWitt County. Its the first wind farm application in the county.. Last month, the Regional Planning Commission voted 3-1 with two abstentions against a positive recommendation, but that wasnt necessarily a defeat, said Tom Swierczewski, a development director for the proposed Alta Farms II project.. "I think there are a lot of project details that are being overlooked," he said. "People really havent had the chance to ask questions about the specifics and that is an important part of the ZBA process.". The company is asking to build and operate a wind energy ...
Wind Power Basics. (7.5 credits, Autumn17/18, weeks 35-43, 50%. 7.5 credits, Spring17/18, weeks 03-11, 50%.). The Wind Power Basics course gives you a basic understanding of wind power, how a wind turbine works, knowledge of wind resources, the permissions needed for development, the environmental impacts of wind power and some useful economic calculations.
The global wind energy market witnessed huge growth from 2009 to 2010 as total wind power capacity grew by 22.3%. The global wind energy installed capacity increased at a Compound Annual Growth Rate(CAGR) of 27.9% from 74,107 megawatt (MW) in 2006 to 198,203 MW in 2010, of which 36,100 MW went online in 2010. Although the cumulative capacity for wind power grew, there was a 10.9% fall in annual additions in 2010 as major wind markets such as the US, Germany and Spain faced economic problems following the global economic crisis. The global wind power markets are expected to recover in 2011 due to the huge order intake by major wind manufacturers, the growing Asia-Pacific (APAC) region, emerging South America and Africa regions, steady European wind markets and recovery in North America. Wind power manufacturers across the world had a high order intake in 2010 with expected delivery deadlines in 2011 and 2012. This will contribute to the annual installations in 2011-2012 ...
At the end of 2012, the European market boasted 55 offshore wind farms and the U.S. had absolutely none. The question arises: "Whats the holdup?". There are a wide variety of answers to that inquiry. However, many are cleared up by Cleantechnica.coms new report, titled "Where Do I Put My Offshore Wind Farm?," a two-page synopsis on the present status of wind farms in the U.S. as a source of alternative energy.. This short analysis links readers to a vast wealth of information on this emerging industry and touches on such diverse issues as initial funding, siting, wind speeds, water depths, federal vs. state waters, transmission lines, hurricane risk, and public opinion.. Ironically, the political factor is not highlighted in this assessment. With new drive for America to invest in energy independence, it seems that future development of offshore wind farms has the solid political support of many governors - especially those on the East Coast. ...

While large wind mills that are installed in clusters at wind farms produce energy on a massive scale, small wind turbines produce energy at lower levels. Unlike large wind turbines, this technology helps produce wind energy in the low to medium paced wind conditions and is developed to promote in-house energy production among households, farms and small businesses. Wind energy has long been exploited as a significant alternative source of power generation in the country through large wind mills. But, they require high speed winds to produce electricity. In this scenario, small wind turbines technology has surfaced as a remarkable development in the wind energy sector as it generates power in low and medium paced wind. This technology, therefore, is ideal for country like India where majority of regions have low to medium paced winds. Small Wind Turbines (SWT), though in its infancy stage, is set to evolve and grow large as it taps full potential of wind in generating sustainable, economical and ...
1. The advantages offered by utilizing wind energy to develop aquaculture production not only include promoting fish or shrimp growth, lowering of incidence of disease, using less feed and increasing fish yield, but also include saving conventional energy (fuel or electricity) consumption. At present, there are more than 60, 000 sets of oxygen-enhancing equipment in China. Most of the equipment is being driven by fuel or electricity. However, the price of fuel and electricity are high. On the other hand, in some sparsely populated regions as well as islands and remote border regions, the national electricity grid has not yet been installed or electricity supply is serious inadequate. Since wind energy source is considerably abundant in these regions, the prospects of utilizing wind energy to develop fishery is bright in these regions. 2. As mentioned above, it is important for fish, especially for prawn, to replace old water in fishponds with fresh water. Regulating water quality is a key link ...

Dutch Wind Energy Research Preface Wind energy research and education in the Netherlands We are very pleased to present you an overview of the wind energy research and education in the Netherlands. It
Most offshore wind turbines (OWTs) are designed according to the international standard IEC 61400-3 which requires consideration of several design load cases under 50-year extreme storm conditions during which the wind turbine is not operational (i.e. the rotor is parked and blades are feathered). Each of these load cases depends on combinations of at least three jointly distributed metocean parameters, the mean wind speed, the significant wave height, and the peak spectral period. In practice, these variables are commonly estimated for the 50-year extreme storm using a simple but coarse method, wherein 50-year values of wind speed and wave height are calculated independently and combined with a range of peak spectral period conditioned on the 50-year wave height. The IEC Standard does not provide detailed guidance on how to calculate the appropriate range of peak spectral period. Given the varying correlation of these parameters from site-to-site, this approach is clearly an approximation which ...
We now have another study that confirms that there are no health impacts associated with living near wind farms.. The study, conducted by Health Canada at a cost of $2.1 million, agrees with the findings of the study by Ontarios Medical Officer of Health, which found no "causal link between wind turbine noise and adverse health effects." A study by the American Psychological Association found the same. So have a myriad of other studies done over the years in multiple jurisdictions.. Health Canadas study found that there was no relationship between wind turbines and reports of trouble sleeping, incidence of self-reported illness, stress, or quality of life.. They did, however, find that some people are annoyed by wind farms. In the language of epidemiology, the study found a correlation, but not a causal relationship, between increasing levels of wind turbine noise and "annoyance.". The authors note that the levels of annoyance may be linked to other issues, such as health, overall economic ...

China is the worlds leader in installed wind power capacity. After years of development in the countrys north, northeastern and northwestern areas, wind power is spreading across China. Greenpeaces annual industry analysis China Wind Power Outlook predicts that Chinas installed wind power capacity will be between 200 and 300 GW by 2020 and over 400 GW by 2030. And that by 2030, wind power will make up about 8.4% of Chinas total electricity generation, and 15% of Chinas installed capacity. It estimates that in 2011 Chinas wind energy sector generated 71.5 billion kilowatt hours, equivalent to the annual electricity demand of over 47 million households.

This research work, named as CryoVent, was focused on determining the feasibility of using wind energy, to produce liquefied gases (cryogens) continuously in a safe approach that can be used for the cooling and ventilation of underground mines. The experimental work performed suggested that the continuous production of liquefied gases with variable input work is practical. The average specific power consumption for liquefaction of nitrogen in this work was 7.86 kWh/kg using the refrigeration produced by helium. This is ~20 times higher than that consumed by industrial scale gas liquefaction systems, but is practical for a small scale system. This specific power consumption could probably be lowered if the working fluid itself is liquefied. Analysis on wind speed variability and wind speed data synthesis were also performed which suggested presence of multi-fractal nature in wind speed data that represent the temporal variation. A new method developed to generate high sampling frequency wind ...
Binatek and UPC initiated the development of both Projects in late 2011 and have conducted rigorous wind data collection and analysis by third party industry experts on this site. PLN has a strong ongoing program on the National Grid of using greater amounts of sustainable clean renewable energy that does not use fossil fuels and the wind farm can be an effective provider of such energy as well as a highly visual demonstration of clean Renewable Energy in Indonesia. As a quickly deployable generation source Wind Power (construction is generally less than 12 months), it can be one more added technology to the mix of choices PLN has to supply the increasing demand for electricity on Indonesias Grid system. Globally, installed wind energy generation reached 300GW in 2013 and as such is a mature technology.. The Samas wind farm will produce zero emission electrical power from large 2.0 - 2.5 MW turbines providing wind electricity to Indonesia without pollution or added CO2 to the environment. As ...

Wind is suspected to be a primary dispersal mechanism for large branchiopod cysts on the Colorado Plateau. We used a wind tunnel to investigate wind velocities capable of moving pothole sediment and cysts from intact and disturbed surfaces. Material moved in the wind tunnel was trapped in filters; cysts were separated from sediment and counted. Undisturbed sediment moved at velocities as low as 5.9 m s-1 (12.3 miles h-1). A single all-terrain vehicle (ATV) track increased the sediment mass collected 10-fold, with particles moving at a wind velocity of only 4.2 m s-1 (8.7 miles h-1). Cysts were recovered from every wind tunnel trial. Measured wind velocities are representative of low-wind speeds measured near Moab, Utah. Wind can move large numbers of cysts to and from potholes on the Colorado Plateau. Our results indicate that large branchiopod cysts move across pothole basins at low-wind speeds; additional work is needed to...
This paper presents a study to assess how wind turbines could increase their energy yield when their grid connection point is not strong enough for the rated power. It is state of the art that in such situations grid operators impose feed-in management on the affected wind turbines, i.e., the maximum power is limited. For this study a 5 MW wind turbine is introduced in a small grid that has only limited power transfer capabilities to the upstream power system. Simulations of one particular day are conducted with the electric load, the temperature, and the wind speed as measured on that day. This simulation is conducted twice: once with the 5 MW wind turbine controlled with conventional feed-in management, and a second time when its power is controlled flexibly, i.e., with continuous feed-in management. The results of these two simulations are compared in terms of grid performance, and in terms of mechanical stress on the 5 MW wind turbine. Finally, the conclusion can be drawn that continuous feed-in
ABERDEEN, S.D. -- A wind energy blade manufacturing company in Aberdeen is closing early next year, leaving 409 people out of work.. Employees were told in a meeting early Wednesday morning.. The company, called Molded Fiber Glass and a staple in the northeastern South Dakota city since 2008, has been making 187 foot blades for General Electric, according to a report in the Aberdeen American News.. General Electric was the companys only client and they plan to work with LM Wind Power, a company they purchased in October 2016 for $1.65 billion, to make the blades.. Also affecting the shutdown was the phasing out of the renewable electricity production tax credit given to companies that manufacture for the wind energy industry.. Aberdeen officials told the newspaper that the company tried to find a buyer, but was unsuccessful. They also said the city is looking at three new companies that may locate there.. Based in Ohio, the company also operates in Alabama, California, Kansas North Carolina, ...

1) The knowledge of wind engineering is used to analyze and design all high rise buildings, cable suspension bridges and cable-stayed bridges, electricity transmission towers and telecommunication towers and all other types of towers and chimneys. The wind load is the dominant load in the analysis of many tall buildings. So wind engineering is essential for the analysis and design of tall buildings. Again, wind load is a dominant load in the analysis and design of all long-span cable bridges.

Xcel Energy is halfway to winning the regulatory approval it needs to move forward with a 750-megawatt wind energy project - enough to power about 200,000 homes. The Minneapolis-based utility said Thursday that the Minnesota Public Utilities Commission has signed off on the plan, which includes the construction of two wind farms in Minnesota and two more in North Dakota. The company expects the North Dakota Public Service Commission to consider the project by the end of the year. "Wind energy is a clean, low-cost substitute for natural gas and other fuels right now," said Dave Sparby, a senior vice president at Xcel Energy, in a statement. "These cost-competitive projects will save customers money by providing a valuable hedge to rising and volatile fuel prices well into the future." Sparby added that the projects will save Xcel customers "more than $225 million over the projects lives." The four wind farms proposed in the plan include Courtenay Wind Farm near Jamestown, N.D., the Odell Wind ...
Objectives: Health-related quality of life (HRQoL) can serve as a multidimensional means of evaluating the relationship between the presence of wind turbines in residential areas and their consequence for health. The purpose of this study was to determine whether a relationship exists between the presence of wind farms at different stages of development and the HRQoL of people living in their vicinity in Poland. Method: The instruments employed in this study were the SF-36v2, a questionnaire measuring self-reported health problems, and a sociodemographic questionnaire. The study involved 1277 people who lived within 2 km from a wind turbine. Results: The highest overall QoL scores were obtained by respondents living the closest to wind turbines. The mental health, role emotional, and social functioning scores were significantly higher among respondents living near wind farms and wind-farm construction sites than among those living close to locations where wind farms were planned but where construction

The vertical axis wind turbine design depicted in (Fig.1) is widely considered a wind turbine of a wind power generation system because it can be easily miniaturized, it generates low noise, and it rotates regardless of wind direction. The vertical axis wind turbine has, however, low rotation performance when compared with that of a horizontal axis wind turbine. Therefore, we need to improve the rotation performance of the vertical axis wind turbine. This study proposes a new blade shape of a vertical axis wind turbine effective for a wide range of wind speed. A proposed new blade profile has largely rounded leading and trailing edges, see Fig. 2. Performance of this new blade was first simulated by COMSOL Multiphysics® using the CFD module. Some examples of simulated pressure distribution are shown in Fig. 3. Simulated results were then confirmed by wind tunnel experiments. As shown in Fig. 4, results obtained by numerical simulation and wind tunnel experiments are in good agreement. These ...
Siemens (NYSE: SI) today announced the premier of its new wind turbine. The SWT-2.3-120 is the first wind turbine specifically designed by the company to meet the demands of its North and South American customers. The powerful new turbine features a 120-meter rotor, enabling it to achieve an industry-leading capacity factor. It represents the next step in the evolution of Siemens proven G2 product platform. Serial production of the SWT-2.3-120 will commence in the U.S. in 2017.. The product was developed with an eye toward increasing energy production for sites with medium to low wind conditions, which are prevalent in markets within the Americas region. It employs advanced technology including a newly-developed 59-meter long rotor blade, which has been optimized for enhanced production at medium to low wind speeds, while also reducing weights and loads for decreased wear and tear. Siemens blade factory in Fort Madison, Iowa, and its aerodynamic engineering center in Boulder, Colorado, were ...
