1992-01-01

Wind energy should be an important part of the energy supply mix, both at home and abroad, to provide cleaner air and a more stable fuel supply. Not only can wind energy contribute to solving complex global issues, it also can provide a large market for American technological leadership. Even though utilities are paying more attention to wind in a number of states, there are no plans for major installations of wind power plants in the United States. At the same time, European nations have developed aggressive wind energy development programs, including both ambitious research and development efforts and market incentives. Many countries recognize the importance of the clean energy provided by wind technology and are taking steps to promote their fledgling domestic industries. The emphasis on market incentives is starting to pay off. In 1991, European utilities and developers installed nearly twice as much wind capacity as Americans did. In 1992 the gap will be even greater. This article reviews aggressive incentives offered by European governments to boost their domestic wind industries at home and abroad in this almost $1 billion per year market. By offering substantial incentives - considerably more than the American Wind Energy Association (AWEA) is proposing - European nations are ensuring dramatic near-term wind energy development and are taking a major step toward dominating the international wind industry of the 21st century

As a consequence of the growing wind energy market in Germany the importance of the industry in this business are has grown. In 1994 the turnover will go beyond 500 million DM, and the number of employees will reach 2,900. The turnover and the number of employees are increasing in spite of the higher efficiency. In 1994 only 5 employees are needed by a manufacturer to install 1 MW rated power instead of 15 in 1989, and the ratio of installed power to manufacturer's turnover has risen from 0,25 W/DM in 1988 to 0,455 W/DM in 1994. On the other hand the turnover of the manufacturers per employee has increased from 80,000 DM in 1988 to 440,000 DM in 1994. Economic development has considerably been advanced by subsidies for the application of wind energy technology. (orig.)

In support of the U.S. Department of Energy (DOE) Wind and Water Power Technologies Office (WWPTO) goals, researchers from DOE's National Renewable Energy Laboratory (NREL), National Wind Technology Center (NWTC) are investigating the Distributed Wind Resource Assessment (DWRA) process, which includes pre-construction energy estimation as well as turbine site suitability assessment. DWRA can have a direct impact on the Wind Program goals of maximizing stakeholder confidence in turbine performance and safety as well as reducing the levelized cost of energy (LCOE). One of the major components of the LCOE equation is annual energy production. DWRA improvements can maximize the annual energy production, thereby lowering the overall LCOE and improving stakeholder confidence in the distributed wind technology sector by providing more accurate predictions of power production. Over the long term, one of the most significant benefits of a more defined DWRA process could be new turbine designs, tuned to site-specific characteristics that will help the distributed wind industry follow a similar trajectory to the low-wind-speed designs in the utility-scale industry sector. By understanding the wind resource better, the industry could install larger rotors, capture more energy, and as a result, increase deployment while lowering the LCOE. a direct impact on the Wind Program goals of maximizing stakeholder confidence in turbine performance and safety as well as reducing the levelized cost of energy (LCOE).

The recording, analyzing and publishing of statistics of wind energy production has been reorganized in cooperation of VTT Energy, Finnish Meteorological (FMI Energy) and Finnish Wind Energy Association (STY) and supported by the Ministry of Trade and Industry (KTM). VTT Energy has developed a database that contains both monthly data and information on the wind turbines, sites and operators involved. The monthly production figures together with component failure statistics are collected from the operators by VTT Energy, who produces the final wind energy statistics to be published in Tuulensilmae and reported to energy statistics in Finland and abroad (Statistics Finland, Eurostat, IEA). To be able to verify the annual and monthly wind energy potential with average wind energy climate a production index in adopted. The index gives the expected wind energy production at various areas in Finland calculated using real wind speed observations, air density and a power curve for a typical 500 kW-wind turbine. FMI Energy has produced the average figures for four weather stations using the data from 1985-1996, and produces the monthly figures. (orig.)

The wind industry and the U.S. Department of Energy (DOE) are addressing technical challenges to increasing wind energy's contribution to the national grid (such as reducing turbine costs and increasing energy production and reliability), and they recognize that public acceptance issues can be challenges for wind energy deployment. Wind project development decisions are best made using unbiased information about the benefits and impacts of wind energy. In 2014, DOE established six wind Regional Resource Centers (RRCs) to provide information about wind energy, focusing on regional qualities. This document summarizes the status and drivers for U.S. wind energy development on regional and state levels. It is intended to be a companion to DOE's 2014 Distributed Wind Market Report, 2014 Wind Technologies Market Report, and 2014 Offshore Wind Market and Economic Analysis that provide assessments of the national wind markets for each of these technologies.

Since 2010, the ADEME has been managing four programmes within the scope of 'Future Investments'. Groups of research experts from various industrial fields, research bodies and research programming and financing agencies are responsible, within the scope of collective works, for producing strategic road-maps. These are used to launch Calls for Expressions of Interest (CEI). With regard to wind energy, the purpose of this road-map is to: - Highlight the industrial, technological, environmental and societal challenges encountered in the development of 'Industrial Wind'; - Draw up middle and long-term coherent, shared visions of the socio-technical systems or technologies in question; - Identify the technological, organisational, environmental and socio-economic obstacles, and therefore initiate (or pursue) the development of high-performance and economically viable technologies; - Promote the research, development and demonstration requirements ('technological demonstrators' to validate innovative technological solutions), experimentation requirements and technology platforms to be deployed ('pilot' projects to be tested under real circumstances: 'pre-commercial' unit prototypes then 'pre-commercial pilot farms') to improve the competitiveness of offers and companies within this sector, to reach the ambitious objectives set within the framework of the Grenelle Environnement and to promote and support the development of a French wind energy industry. These needs can then act as a basis for: - drawing up CEIs; - programming research within the ADEME and other institutions such as the Agence nationale de la recherche (ANR - French National Research Agency), the Comite strategique national sur la recherche energie (French national strategic committee for energy research) and the Alliance nationale de coordination de la recherche pour l'energie (ANCRE - French national alliance for the coordination of energy research).

Global wind energy outlook 2006

International Nuclear Information System (INIS)

2006-09-01

The global market for wind power has been expanding faster than any other source of renewable energy. From just 4,800 MW in 1995 the world total has multiplied more than twelve-fold to reach over 59,000 MW at the end of 2005. The international market is expected to have an annual turnover in 2006 of more than euro 13 billion, with an estimated 150,000 people employed around the world. The success of the industry has attracted investors from the mainstream finance and traditional energy sectors. In a number of countries the proportion of electricity generated by wind power is now challenging conventional fuels. The Global Wind Energy Outlook 2006 reports that over a third of the world's electricity - crucially including that required by industry - can realistically be supplied by wind energy by the middle of the century. The report provides an industry blueprint that explains how wind power could supply 34% of the world's electricity by 2050. Most importantly, it concludes that if wind turbine capacity implemented on this scale it would save 113 billion tonnes of CO2 from entering the atmosphere by 2050. This places wind power as one of the world's most important energy sources for the 21st century. The 'Global Wind Energy Outlook 2006' runs three different scenarios for wind power - a Reference scenario based on figures from the International Energy Agency (IEA); a Moderate version which assumes that current targets for renewable energy are successful; and an advanced version assuming that all policy options in favour of renewables have been adopted. These are then set against two scenarios for global energy demand. Under the Reference scenario, growth in demand is again based on IEA projections; under the High Energy Efficiency version, a range of energy efficiency measures result in a substantial reduction in demand

Klagge, Britta; Liu Zhigao; Campos Silva, Pedro

2012-01-01

The rapid rise of China as the largest wind energy market worldwide with several global leaders in turbine manufacturing received much attention from both scholarly and policy-analytical work. However, little attention has been given to the innovation activities of the Chinese wind industry. In our paper, we aim to address this gap, based on second-hand sources and over 50 personal interviews with wind energy-related experts. We argue that China’s wind industry has made great progress in terms of manufacturing and installing, but is confronted with various challenges and problems regarding the development of its indigenous innovation capabilities. Using innovation systems approaches as an analytical tool and focusing on institutions, actors, technology and their interaction in supporting innovation activities, we decompose the elements of China’s wind energy innovation system and their role in developing the domestic wind industry. Against this backdrop we identify and discuss challenges and obstacles in the development of an innovation-driven wind industry in China. The paper strongly argues that more attention should be paid to improve the coordination and cooperation among the various actors of the wind energy innovation system, to the build-up of a market-oriented education and training system as well as to intellectual property protection. - Highlights: ► Innovation systems concepts as analytical tool to understand wind energy in China. ► Focus on institutions, actor constellations and technology development in China. ► Analysis of success in manufacturing and the rapid rise of China’s wind industry. ► Identification of challenges and problems regarding innovation activities. ► Recommendation to (better) integrate innovation policy and wind industry policy.

Wind Observatory 2017. Analysis of the wind power market, wind jobs and future of the wind industry in France

International Nuclear Information System (INIS)

2017-09-01

Two years after the enactment of the Energy Transition for Green Growth Act, wind power capacity continues to grow in France, exceeding 12 GWatt the end of 2016 and soon to account for 5% of France's electric power consumption. This vitality, which is set to continue in 2017, will help France achieve its objectives of an installed capacity of 15,000 MW in onshore wind by 2018 and 21,800 to 26,000 MW by 2023. The current pace will nevertheless have to be accelerated in order to reach the realistic objective of 26 GW by 2023 mentioned in the multi-annual energy plan (PPE). With 1,400 jobs created in one year and more than 3,300 over the last two years, the relevance of wind power as a driving force of sustainable job creation throughout the country is unequivocally confirmed: the increase in wind power capacity continues to contribute to the growth in employment in the country. Prepared in collaboration with the consulting firm BearingPoint, the 2017 edition of the Observatory aims to give the reader an overview of employment in the wind industry and the wind power market over the period under consideration. Any changes from the three previous editions are highlighted. It is based on a comprehensive census of all market participants on three themes: employment, the market and the future of wind power. The Observatory gives an accurate picture of how the wind energy industry is structured, thereby presenting a precise overview of the wind energy industry and all its components

Mahoney, W. P.; Wiener, G.; Liu, Y.; Myers, W.; Johnson, D.

2010-12-01

Wind energy decision makers are required to make critical judgments on a daily basis with regard to energy generation, distribution, demand, storage, and integration. Accurate knowledge of the present and future state of the atmosphere is vital in making these decisions. As wind energy portfolios expand, this forecast problem is taking on new urgency because wind forecast inaccuracies frequently lead to substantial economic losses and constrain the national expansion of renewable energy. Improved weather prediction and precise spatial analysis of small-scale weather events are crucial for renewable energy management. In early 2009, the National Center for Atmospheric Research (NCAR) began a collaborative project with Xcel Energy Services, Inc. to perform research and develop technologies to improve Xcel Energy's ability to increase the amount of wind energy in their generation portfolio. The agreement and scope of work was designed to provide highly detailed, localized wind energy forecasts to enable Xcel Energy to more efficiently integrate electricity generated from wind into the power grid. The wind prediction technologies are designed to help Xcel Energy operators make critical decisions about powering down traditional coal and natural gas-powered plants when sufficient wind energy is predicted. The wind prediction technologies have been designed to cover Xcel Energy wind resources spanning a region from Wisconsin to New Mexico. The goal of the project is not only to improve Xcel Energy’s wind energy prediction capabilities, but also to make technological advancements in wind and wind energy prediction, expand our knowledge of boundary layer meteorology, and share the results across the renewable energy industry. To generate wind energy forecasts, NCAR is incorporating observations of current atmospheric conditions from a variety of sources including satellites, aircraft, weather radars, ground-based weather stations, wind profilers, and even wind sensors on

Valuing carbon assets for high-tech with application to the wind energy industry

International Nuclear Information System (INIS)

Han, Liyan; Liu, Yang; Lin, Qiang; Huang, Gubo

2015-01-01

In contrast to the traditional methods for high-tech evaluation, we introduce a new, more active idea for considering the carbon asset effect, in addition to the economic and technological considerations for strategic significance. The method proposed in this paper considers a reduced amount of carbon emissions, less than that of the current industry baseline, to be an asset that is beneficial to a firm that adopts a new technology. The measured carbon asset values vary across different technologies, in different industries and over time. The new method is applied to the valuing of wind energy technology and uses the Weibull distribution to estimate the wind energy capacity and a concrete sensitivity analysis. These applications support the validity of the new method and show that the impact of the fluctuations of carbon sinks on the values of carbon assets is significantly greater than that of volatility in the production output. The paper also presents some policy recommendations based on the results. - Highlights: • Carbon asset dimension for high-tech evaluation. • Valuing wind energy technology by Weibull distribution. • Greater impact of the carbon sink price on the carbon asset value than that of production output. • The environmental risk could be measured based on the carbon asset assessment.

Wind energy in the United States and materials required for the land-based wind turbine industry from 2010 through 2030

Science.gov (United States)

Wilburn, David R.

2011-01-01

The generation of electricity in the United States from wind-powered turbines is increasing. An understanding of the sources and abundance of raw materials required by the wind turbine industry and the many uses for these materials is necessary to assess the effect of this industry's growth on future demand for selected raw materials relative to the historical demand for these materials. The U.S. Geological Survey developed estimates of future requirements for raw (and some recycled) materials based on the assumption that wind energy will supply 20 percent of the electricity consumed in the United States by 2030. Economic, environmental, political, and technological considerations and trends reported for 2009 were used as a baseline. Estimates for the quantity of materials in typical "current generation" and "next generation" wind turbines were developed. In addition, estimates for the annual and total material requirements were developed based on the growth necessary for wind energy when converted in a wind powerplant to generate 20 percent of the U.S. supply of electricity by 2030. The results of the study suggest that achieving the market goal of 20 percent by 2030 would require an average annual consumption of about 6.8 million metric tons of concrete, 1.5 million metric tons of steel, 310,000 metric tons of cast iron, 40,000 metric tons of copper, and 380 metric tons of the rare-earth element neodymium. With the exception of neodymium, these material requirements represent less than 3 percent of the U.S. apparent consumption for 2008. Recycled material could supply about 3 percent of the total steel required for wind turbine production from 2010 through 2030, 4 percent of the aluminum required, and 3 percent of the copper required. The data suggest that, with the possible exception of rare-earth elements, there should not be a shortage of the principal materials required for electricity generation from wind energy. There may, however, be selective

Such interest necessitates a greater depth of understanding of the wind power sector if informed choices and policy decisions are to be made. The European Wind Energy Association (EWEA), and the European Commission's Directorate General for Transport' and Energy have collaborated on this report to provide a detailed overview of the wind power sector. Wind Enera - The Facts provides a comprehenslve overview of the essential issues concerning wind power today: technology, cost, prices, environment, industry and employment, market, and research and development. Wind energy is a relatively young but rapidly expanding industry. Over the past decade, global installed capacity has increased from 2,500 megawatts (MW) in 1992 to just over 40,000 MW at the end of 2003, at an annual growth rate of near 30%. Almost three quarters of this capacity has been installed in Europe. Penetration levels in the electricity sector have reached 20% in Denmark and about 5% in both Germany and Spain. The north German state of Schleswig-Holstein has 1,800 MW of installed wind capacity, enough to meet 30% of the region's total electricity demand, while in Navarra, in Spain, 50% of consumption is met by wind power. If positive policy support continues to develop, EWEA has projected that wind power will achieve an installed capacity of 75,000 MW in the EU-15 by 2010. This would represent an overall contribution to electricity supply of 5.5%. By 2020, this figure is expected to increase to more than 12%, with wind power providing energy equal to the demand of 195 million European household consumers. (au)

Fostering a renewable energy technology industry: an international comparison of wind industry policy support mechanisms

International Nuclear Information System (INIS)

Lewis, J.I.; Wiser, R.H.

This article examines the importance of national and sub-national policies in supporting the development of successful global wind turbine manufacturing companies. We explore the motivations behind establishing a local wind power industry, and the paths that different countries have taken to develop indigenous large wind turbine manufacturing industries within their borders. This is done through a cross-country comparison of the policy support mechanisms that have been employed to directly and indirectly promote wind technology manufacturing in 12 countries. We find that in many instances there is a clear relationship between a manufacturer's success in its home country market and its eventual success in the global wind power market. Whether new wind turbine manufacturing entrants are able to succeed will likely depend in part on the utilization of their turbines in their own domestic market, which is turn will be influenced by the annual size and stability of that market. Consequently, policies that support a sizable, stable market for wind power, in conjunction with policies that specifically provide incentives for wind power technology to be manufactured locally, are most likely to result in the establishment of an internationally competitive wind industry.

Yu, Wang; Sheble, Gerald B.; Lopes, Joao A. Pecas; Matos, Manuel Antonio

2006-01-01

The current fixed tariff remuneration for wind energy is not compatible with the deregulation of the electric power industry. The time-varying and location-dependent value of renewable energy is not acknowledged. The newly announced switchable tariff for wind energy in the Spanish electricity market provides a promising solution to compensating renewable energy within the deregulated electric power industry. The new switchable tariff provides wind generators more flexibility in operating wind generation assets. Such flexibilities provide option value in coordinating the seasonality of wind energy, demand on electric power and electricity prices movement. This paper models and valuates the flexibility on switching tariff as real compound options for wind generators. Numerical examples valuate wind generation assets under fixed tariff, spot market price taking, and yearly and monthly switchable tariffs. The optimal switching strategies are identified. The impacts of the switchable tariff on sitting criteria and values of wind generation assets are investigated. An improvement on the yearly switchable tariff is suggested to further reduce the operation risk of wind generators and fully explore the efficiency provided by competitive electricity markets.

With over 5, 660 MW installed in end-2010, France ranks fourth in Europe, behind Germany, Spain and Italy. The wind power industry currently employs almost 11, 000 people in France throughout the value chain. In 2009, the first edition of this directory listed over one hundred companies working in around twenty different areas. Encouraged by these initial positive results, and with the help of ADEME, the French syndicate for renewable energies (SER) asked Capgemini Consulting to undertake a study to identify and raise awareness among French industrials likely to enter into the wind energy market. The French Ministry for Ecology, Energy, Sustainable Development and the Sea, along with the Ministry for the Economy, Finance and Employment, were involved in the work. 400 companies were questioned as part of the study. Over 150 replies testified to the dynamic character of the wind power market in France and overseas, and the opportunities for diversification that it represents for traditional industries like metallurgy, aeronautics, defence and shipyards, etc. The study led to the creation of the initiative Windustry France, which currently groups over 300 companies either active in the French wind power market or set to enter it. Windustry France is a showcase of the industrial know-how that can be used in the wind power industry both onshore and offshore. It includes local set-ups developed around major fields of activity (e.g. car industry, aeronautics, mechanics, etc.) and industrial port zones (Dunkerque, Rouen/Le Havre, Brest, Nantes Saint-Nazaire, Bordeaux, etc.). Several ministries, regional stakeholders and authorities are also involved (local authorities, Regional directorates for industry, research and the environment (DReal) networks and chambers of commerce and industry), all of which contribute to making Windustry France a collective approach to industrial policy.

Wind energy is a kind of clean renewable energy, which is also relatively mature in technology, with large-scale development conditions and prospect for the commercialization. The development of wind energy is a systematic project, involving policy, law, technology, economy, society, environment, education and other aspects. The relation-ship among all the aspects should be well treated and coordinated. This paper has discussed the following relationships which should be well coordinated: relationship between wind resources and wind energy development, relationship be-tween the wind turbine generator system and the components, relationship between wind energy technology and wind en-ergy industry, relationship between off-grid wind power and grid-connected wind power, relationship between wind farm and the power grid, relationship between onshore wind power and offshore wind power, relationship between wind energy and other energies, relationship between technology introduction and self-innovation, relationship among foreign-funded, joint ventured and domestic-funded enterprises and relationship between the government guidance and the market regula-tion, as well as giving out some suggestions.

Wind, in South Africa, has been a source of energy for many years but at the same time it is taking as much time and effort to receive the recognition it deserves as anywhere else in the world. The wind resource is comparable to a number of areas in the world wind is exploited as a grid connected source of electrical energy. Although the environmental impact of conventional sources of energy is not as widespread as most of the industrial nations some areas should be looked at critically. Wind as a bulk generator of energy is tentatively being looked at with some demonstration projects being planned. (author)

1998-01-01

The current status of wind technology developments in Canada and around the world was reviewed. Information regarding the level of wind turbine deployment was presented. It was shown that significant effort has been made on the national and international level to increase the capacity of this clean, non-polluting form of energy. Wind energy has become competitive with conventional sources of electricity due to lower cost, higher efficiency and improved reliability of generating equipment. The advantages and disadvantages of wind electricity generating systems and the economics and atmospheric emissions of the systems were described. At present, there is about 23 MW of wind energy generating capacity installed in Canada, but the potential is very large. It was suggested that wind energy could supply as much as 60 per cent of Canada's electricity needs if only one per cent of the land with 'good winds' were covered by wind turbines. Recently, the Canadian government has provided an accelerated capital cost allowance for certain types of renewable energies under the Income Tax Act, and the flow-through share financing legislation to include intangible expenses in certain renewable energy projects has been extended. Besides the support provided to the private sector through tax advantages, the Government also supports renewable energy development by purchasing 'green' energy for its own buildings across the country, and by funding a research and development program to identify and promote application of wind energy technologies, improve its cost effectiveness, and support Canadian wind energy industries with technology development to enhance their competitiveness at home and abroad. Details of the Wind Energy Program, operated by Natural Resources Canada, are described. 3 tabs., 5 figs

Limitation of solar energy and wind energy

International Nuclear Information System (INIS)

White, R. S.

2008-01-01

Wind turbines, solar energy collectors and photovoltaic cells have been popular sources of electricity since the oil crisis in the late seventies, and they are increasingly favored by many scientists and much of the public as methods for reducing global warming. The older wind farms in California are outdated. New wind turbines have not followed, primarily because of competition from lower-cost natural gas. The Times urges increased federal and state subsidies for the wind and solar industries. The primary reason that wind and solar energies have not made inroads in the past, and will never supply more than a few percentage points of the world's electrical energy, is their unpredictable variations in time and their constant need for back-ups. The only non-carbon-dioxide-emitting generator capable of backing up wind and solar energy and replacing coal and gas generators is nuclear fission. Nuclear power may be the practical solution to global warming, after all.

Feurtey, E.

2008-01-01

This document was prepared as part of a decentralized collaboration between Quebec and France to share knowledge regarding strategies and best practices in wind power development. It reviewed the social acceptance of Quebec's wind power industry, particularly at the municipal level. The wind industry is growing rapidly in Quebec, and this growth has generated many reactions ranging from positive to negative. The purpose of this joint effort was to describe decision making steps to developing a wind turbine array. The history of wind development in Quebec was discussed along with the various hardware components required in a wind turbine and different types of installations. The key element in implementing wind turbine arrays is to establish public acceptance of the project, followed by a good regulatory framework to define the roles and responsibilities of participants. The production of electricity from wind turbines constitutes a clean and renewable source of energy. Although it is associated with a reduction in greenhouse gas emissions, this form of energy can also have negative environmental impacts, including noise. The revenues generated by wind parks are important factors in the decision making process. Two case studies in Quebec were presented. refs., tabs., figs.

China's wind industry: Leading in deployment, lagging in innovation

International Nuclear Information System (INIS)

Lam, Long T.; Branstetter, Lee; Azevedo, Inês M.L.

2017-01-01

China's massive carbon emissions and air pollution concerns have led its government to embrace clean energy innovation as a means of transitioning to a more sustainable energy system. We address the question of whether China's wind industry has become an important source of clean energy technology innovation. We find that in terms of wind capacity expansion, China has delivered enormous progress, increasing its wind capacity from virtually no wind capacity in the early 2000s to 140 GW by 2015. However, in terms of innovation and cost competitiveness, the outcomes were more limited: Chinese wind turbine manufacturers have secured few international patents and achieved moderate learning rates compared to the global industry's historical learning rate. Leading China-based indigenous producers are likely to remain important global players for the foreseeable future, but further progress in reducing the cost of capital equipment may slow relative to the recent past. However, opportunities in lowering curtailment rates and improving turbine quality can reduce China's overall levelized cost of electricity for wind. - Highlights: • Analyze wind power patenting trends of Chinese inventors and firms. • Many Chinese patents, though few were granted by foreign patent offices. • Chinese international patents are less likely to be cited than foreign counterparts. • China's wind industry managed to reduce production costs, but learning rate is low.

Assessment of solar and wind energy potentials for three free economic and industrial zones of Iran

Mohammadi, Kasra; Mostafaeipour, Ali; Sabzpooshani, Majid

2014-01-01

This paper aims to evaluate the potential of renewable energy sources of solar and wind in three free economic and industrial zones of Chabahar, Kish and Salafchegan in Iran. Feasibility of harnessing solar energy was investigated by using key solar parameters like monthly mean global, beam and diffuse solar radiation as well as clearness index. It was found that all locations had great potentials for utilizing different solar energy systems. Additionally, the monthly, seasonal, semi-yearly and yearly optimum tilt angles of south-facing solar surfaces were determined. For all zones, adjusting the tilt angle twice a year or in other words, the semi-yearly tilt adjustment for two periods of warm (April–September) and cold (October–March) were highly recommended, since it offers almost the same level of annual solar energy gain (SEG) as those of monthly and seasonal adjustments. Weibull Distribution Function (WDF) was performed for analyzing the wind potentials at different heights. It was found that Chabahar was not suitable for wind energy development, but Kish and Salafchegan with yearly wind powers of 111.28 W/m 2 and 114.34 W/m 2 , respectively ranked in class 2 which are considered marginal for wind power development. Three different wind turbine models were proposed for Kish and Salafchegan. - Highlights: • Feasibility of solar and wind energy for three locations of Iran was investigated. • All locations were suitable for solar energy utilization. • The optimum tilt angles of solar surfaces were determined. • Chabahar was unsuitable, but Kish and Salafchegan were marginal for wind purpose

Is Germany's energy transition a case of successful green industrial policy? Contrasting wind and solar PV

International Nuclear Information System (INIS)

Pegels, Anna; Lütkenhorst, Wilfried

2014-01-01

In this paper, we address the challenge of Germany's energy transition (Energiewende) as the centrepiece of the country's green industrial policy. In addition to contributing to global climate change objectives, the Energiewende is intended to create a leading position for German industry in renewable energy technologies, boost innovative capabilities and create employment opportunities in future growth markets at the least possible cost. The success in reaching these aims, and indeed the future of the entire concept, is hotly debated. The paper aims to provide an up-to-date assessment of what has become a fierce controversy by comparing solar photovoltaic (PV) and wind energy along five policy objectives: (1) competitiveness, (2) innovation, (3) job creation, (4) climate change mitigation, and (5) cost. We find mixed evidence that Germany reaches its green industrial policy aims at reasonable costs. Wind energy seems to perform better against all policy objectives, while the solar PV sector has come under intense pressure from international competition. However, this is only a snapshot of current performance, and the long term and systemic perspective required for the energy sector transformation suggests a need for a balanced mix of a variety of clean energy sources. - Highlights: • We give an up-to-date assessment of costs and benefits of Germany's Energiewende. • We compare solar PV and wind to show key elements of policy success. • Considered policy objectives: competitiveness, innovation, jobs, emissions, costs. • Wind energy seems to perform better than solar PV against all policy objectives. • The results are a snapshot: a deep transformation requires energy diversification

The American Wind Energy Association (AWEA) has set forth the following wind energy industry objectives for the year 2000: (1) to achieve 10,000 MW cumulative, grid-connected wind power capacity in the United States; (2) to build a $4 billion domestic wind industry base capable of delivering at least 3,000 MW of turbine production per year; (3) to create tens of thousands of new, long-term, skilled jobs, primarily in the manufacturing sector; (4) to achieve levelized costs below four cents per kWh and capital costs 30 percent lower than current costs; (5) to make wind power a major renewable energy option in achieving the nation's' global climate change objectives; (6) to make the US wind power industry the world's technology leader and lowest-cost supplier. This paper will describe the industry's progress toward meeting these goals by presenting the milestones that have been achieved over the last year. In addition, the paper will discuss the Association's strategy for addressing remaining obstacles and moving wind energy into the status of a generally accepted utility technology and one of the lowest cost providers of bulk power for the 21st century

There are more than 100,000 jobs in the U.S. wind industry today, and the second-fastest growing job in the United States in 2017 was wind technician. A vibrant wind industry needs workers, and students who graduate from wind energy education and training programs need jobs. The goal of this research is to better understand the needs of wind-related businesses, education and training requirements, and the make-up of current and future domestic workforces. Educators are developing and training future workers. Educational institutions need to know which courses to provide to connect students with potential employers and to justify their wind energy programs by being able to place graduates into well-paying jobs. In interviews with 250 wind energy firms and 50 educational institutions, many respondents reported difficulty hiring qualified candidates, while many educational institutions reported graduates not finding jobs in the wind industry. We refer to this mismatch as the 'workforce gap.' This conference poster explores this gap.

British Columbia (BC) possesses significant wind energy resources, and many wind energy projects are currently in the planning phase or are already under construction. Wind power policies in the province have been designed to ensure the secure and orderly development of the wind power industry. Policies in the province include a 10-year exemption from participation rents for new projects as well as a policy that has established the maximum permissible noise levels for wind farms located near residential properties. BC's wind power development plan forms part of the province's aim to become electricity self-sufficient by 2016 while ensuring that clean or renewable energy generation accounts for at least 90 per cent of total generation. This guide provided an outline of the province's wind energy sector, and provided a listing of selected wind power operators. Details of new wind power projects were also presented. 11 fig.

Employment opportunities in the United Kingdom wind power industry are reviewed and compared to job availability in Europe, Canada and the USA, using a postal questionnaire. Most jobs were in manufacturing with consultancy and contract research forming another large group; with over two-thirds being in medium to microsized organizations, a size distribution similar to the manufacturing sector of the United Kingdom economy. Professional and management occupations account for over half of the total jobs making the wind industry a highly skilled area. Estimates suggest that, taking account of direct jobs, and those indirectly associated with the wind power industry, only about 2200 full-time equivalent jobs currently exist in the United Kingdom.

According to the World Wind Energy Association the total wind generation capacity worldwide has come close to cover 3% of the world's electricity demand in 2011. Thanks to the enormous resource potential and the relatively low costs of construction and maintenance of wind power plants, the wind energy sector will remain one of the most attractive renewable energy investment options. Studies reveal that climate variability and change pose a new challenge to the entire renewable energy sector, and in particular for wind energy. Stakeholders in the wind energy sector mainly use, if available, site-specific historical climate information to assess wind resources at a given project site. So far, this is the only source of information that investors (e.g., banks) are keen to accept for decisions concerning the financing of wind energy projects. However, one possible wind energy risk at the seasonal scale is the volatility of earnings from year to year investment. The most significant risk is therefore that not enough units of energy (or megawatt hours) can be generated from the project to capture energy sales to pay down debt in any given quarter or year. On the longer time scale the risk is that a project's energy yields fall short of their estimated levels, resulting in revenues that consistently come in below their projection, over the life of the project. The nature of the risk exposure determines considerable interest in wind scenarios, as a potential component of both the planning and operational phase of a renewable energy project. Fundamentally, by using climate projections, the assumption of stationary wind regimes can be compared to other scenarios where large scale changes in atmospheric circulation patterns may affect local wind regimes. In the framework of CLIM-RUN EU FP7 project, climate experts are exploring the potential of seasonal to decadal climate forecast techniques (time-frame 2012-2040) and regional climate scenarios (time horizon 2040+) over the

The development of the Dutch wind energy technology in an international perspective

Beurskens, H.J.M.

1990-01-01

An overview is given of the developments in the Dutch wind energy industry and the position of that industry in the industrialized world. First attention is paid to some historical developments of the modern wind energy technology in the Netherlands compared to some other countries. The start of the Integral Wind energy Program (IPW) at the end of 1985 brought the Dutch know-how of wind energy back on the international level. Next a brief overview is given of governmental wind energy programs which resulted in various projects aimed at designing, testing and implementing wind turbines in the Netherlands. Here too a comparison is made with other countries concerning the realized capacity, investments, and attempts to commercialize the wind turbines. The technological developments in the Netherlands can be characterized as gradual: step-by-step larger wind turbines (i.e. larger capacities) will be developed. The development of multi-megawatt turbines is too risky and too costly at present. Some final remarks state that the present position of the Dutch wind energy industry and the Dutch research activities are good starting-points to realize an important part of the wind energy capacity in Europe, or even the world. Recommendations are given by which the Dutch wind energy industry can operate with success on the international market. 5 figs., 3 tabs., 2 refs

The development of the wind power industry in Quebec

International Nuclear Information System (INIS)

2006-05-01

This analysis examined the current situation of wind power development in the province of Quebec and presented a qualitative assessment of the economic repercussions in terms of employment, investments and environmental and social impacts. The development of the wind power industry in Quebec gained momentum in 2003 when the provincial government expressed support for fast growth of wind power. In response, Hydro-Quebec launched an invitation to interested stakeholders to tender for 1000 MW of wind power projects to be installed between 2006 and 2012. The invitation was a great success, with more than 4000 MW of projects filed. The average price of the selected offers was 6.5 cents per kWh for 990 MW in 8 projects. The economic repercussions related to construction of wind farms in the Gaspe was discussed along with indirect and induced economic repercussions for suppliers and subcontractors in the entire province. It was noted that Quebec is already a leader in the field of electricity and wind energy consultation. Stimulated by these successes, the government of Quebec recently raised its target for wind power development to 2,500 MW. Therefore, taking into account the wind developments already supported by Hydro-Quebec, the installed wind capacity in Quebec is expected to reach more than 4000 MW by 2015, with an investment by the wind power industry of more than 5.8 billion dollars. The wind power industry is expected to generate 45,000 direct or indirect jobs for more than a 20 year period. Presently, the government of Quebec supports the establishment of a local wind market to promote free competition, energy diversity, and coexistence of key players. As its international support mechanism, Quebec chose to integrate regional economic development criteria with the price of electricity. In the long term, the wind industry could constitute a key element in Quebec's sustainable energy development plan. 9 refs., 1 tab

Wind energy, status and opportunities

International Nuclear Information System (INIS)

Van Wijk, A.

1994-01-01

Wind energy is diffuse but was widely used before the industrial revolution. The first oil crisis triggered renewed interest in wind energy technology in remote areas. Winds develop when solar radiation reaches the earth's highly varied surface unevenly, creating temperature density and pressure differences. The earth's atmosphere has to circulate to transport heat from the tropics towards the poles. On a global scale, these atmospheric currents work as an immense energy transfer medium. Three main applications can be distinguished: wind pumps, off-grid applications and grid-connected applications. The total generating costs for wind turbine systems are determined by total investments costs, the life time, the operating and maintenance costs, the wind regime (the wind energy potential is proportional to v 3 where v is the wind speed), the efficiency and availability of the wind turbine. The main gains are achieved as a result of improved reliability. The optimum size of a wind turbine depends on the wind speed, the wind turbine costs, the construction costs, the environmental impact and the social costs. The value of wind energy depends on the application that is made of the energy generated and on the costs of alternatives, it can be calculated by the avoided costs of damage to flora, fauna and mankind due to acid rain deposition, enhancement of the greenhouse effect. The environmental aspects are bird hindrance, noise, telecommunication interference and safety. 2 tabs., 1 fig

When wildlife habitat overlaps with industrial development animals may be harmed. Because wildlife and people select resources to maximize biological fitness and economic return, respectively, we estimated risk, the probability of eagles encountering and being affected by turbines, by overlaying models of resource selection for each entity. This conceptual framework can be applied across multiple spatial scales to understand and mitigate impacts of industry on wildlife. We estimated risk to Golden Eagles (Aquila chrysaetos) from wind energy development in 3 topographically distinct regions of the central Appalachian Mountains of Pennsylvania (United States) based on models of resource selection of wind facilities (n = 43) and of northbound migrating eagles (n = 30). Risk to eagles from wind energy was greatest in the Ridge and Valley region; all 24 eagles that passed through that region used the highest risk landscapes at least once during low altitude flight. In contrast, only half of the birds that entered the Allegheny Plateau region used highest risk landscapes and none did in the Allegheny Mountains. Likewise, in the Allegheny Mountains, the majority of wind turbines (56%) were situated in poor eagle habitat; thus, risk to eagles is lower there than in the Ridge and Valley, where only 1% of turbines are in poor eagle habitat. Risk within individual facilities was extremely variable; on average, facilities had 11% (SD 23; range = 0-100%) of turbines in highest risk landscapes and 26% (SD 30; range = 0-85%) of turbines in the lowest risk landscapes. Our results provide a mechanism for relocating high-risk turbines, and they show the feasibility of this novel and highly adaptable framework for managing risk of harm to wildlife from industrial development. © 2014 Society for Conservation Biology.

A review on global wind energy policy

2010-01-01

With the increasing negative effects of fossil fuel combustion on the environment in addition to limited stock of fossil fuel have forced many countries to inquire into and change to environmentally friendly alternatives that are renewable to sustain the increasing energy demand. Energy policy plays a vital role to mitigate the impacts of global warming and crisis of energy availability. This paper explores the wind energy industry from the point of view of the wind energy policy. It is noticed that energy policy could help increasing wind power generation as well as stimulating the energy industry. It may be stated that without specific energy policy, a country would not be able to solve the acute problems like reducing greenhouse gases (GHGs) emission, scarcity of energy, etc. This paper discussed the existing successful energy policies for few selected countries. Based on literatures, it has been found that FIT, RPS, incentives, pricing law and Quota system are the most useful energy policies practiced by many countries around the world. Then, status of wind energy policy for Malaysia was investigated and compared with few selected countries around the world. (author)

Wind energy is a 'winning reality' in the Netherlands. This is apparent from the results by researchers, industry and the market. During recent years the market has acquired confidence in wind energy. At the start of 1987 there was about 15 MW of installed wind power in the Netherlands. Halfway through 1990 this has almost quadrupled, with 45 MW in operation and 35 MW under construction. The power companies have specific capital expenditure plans for further growth to approximately 400 MW by 1995. This investment scheme will consist of existing turbines (< 600 kW). (Author)

Among all the renewable energies, wind energy knows the strongest progression. The EEC, and more particularly Germany, are at the world top position. Many countries now consider offshore as an alternative to land sites saturation. The three-bladed horizontal axis wind turbines largely dominate the market. The tendency lies now in the multi-megawatts wind turbines exceeding 80 m in diameter. Wind energy takes benefits from mature technologies, since there are less and less expensive and easily exploitable. However many technological challenges still remain to raise. In some countries, the obligation to buy the electricity produced by wind energy at attractive rates allowed the growth of a wind industrial sector, exporting technologies and generating employment. Within the framework of sustainable development, the resource durability has direct repercussions on the local economies. (author)

A Wind Power Plant with Thermal Energy Storage for Improving the Utilization of Wind Energy

Directory of Open Access Journals (Sweden)

Chang Liu

2017-12-01

Full Text Available The development of the wind energy industry is seriously restricted by grid connection issues and wind energy generation rejections introduced by the intermittent nature of wind energy sources. As a solution of these problems, a wind power system integrating with a thermal energy storage (TES system for district heating (DH is designed to make best use of the wind power in the present work. The operation and control of the system are described in detail. A one-dimensional system model of the system is developed based on a generic model library using the object-oriented language Modelica for system modeling. Validations of the main components of the TES module are conducted against experimental results and indicate that the models can be used to simulate the operation of the system. The daily performance of the integrated system is analyzed based on a seven-day operation. And the influences of system configurations on the performance of the integrated system are analyzed. The numerical results show that the integrated system can effectively improve the utilization of total wind energy under great wind power rejection.

The politics and economics of wind energy have played an important role in the development of the industry and contributed to its present success. Engineering is, however, pivotal. As the wind industry has become better established, the central place of engineering has become overshadowed by other issues. This is a tribute to the success of the engineers and their turbines. This volume addresses the key engineering Issues: 1) The turbines - their past achievements and future challenges - a remarkable tale of technical endeavour and entrepreneurship. 2) The wind - its characteristics and reliability - how can it be measured, quantified and harnessed? 3) The wind farms - an assembly of individual turbines into wind power stations or wind farms - their optimisation and development. 4) The grid - transporting the energy from remote locations with plentiful wind energy to the loads - the key technical and strategic challenges. This volume provides an historical overview of turbine development, describes the present status and considers future challenges. This is a remarkable story starting in the nineteenth century and then accelerating through the last two decades of the twentieth century on a course very similar to the early days of aeronautics. The story is far from finished but it has certainly started with a vengeance. Wind must be treated with great respect. The speed of the wind on a site has a very powerful effect on the economics of a wind farm; it provides both the fuel to generate electricity and the loads to destroy the turbine. This volume describes how it can be quantified, harnessed and put to work in an economic and predictable manner. The long-term behaviour of the wind is described as well as its short-term behaviour. The latter can be successfully forecast to allow wind energy to participate in electricity markets. In order for wind to live up to its raw potential promise, individual turbines must be assembled into wind farms or wind power stations

2008-04-15

This article discussed the opportunities that wind energy technology can bring to developing countries in Africa. Solar, hydro and wind energy along with biofuels are among the renewable energy sources being used in Africa, although wind energy is not being used to its potential due to a lack of financial means; constraints in regulatory legislation; lack of structure; lack of knowledge concerning wind energy; and the lack of competent human resources for the installation and management of wind turbines. Technical barriers also exist, such as the lack of interconnection networks and the already existing facilities for power generation. According to a 2004 Canadian study, the greatest potential for wind energy development lies in the northern part of Africa followed by regions in the east, west and south of the continent. Morocco and Tunisia have established regulations regarding wind energy development. Countries such as Algeria and Egypt, which have abundant fossil fuel, would turn to wind energy from an environmental standpoint. The countries of Djibouti, Lesotho, Tchad, Seychelles, Mauritius rely on other forms of renewable energy, including hydro, geothermal, photovoltaic and biofuels. It was concluded that the future of wind energy relies on regional cooperation, technology transfer and subsidies from industrialized nations. 1 fig.

There is now emerging a consensus that the sensitive development of renewable sources of energy, and in particular wind energy, is going to be of major environmental significance for the UK. Primarily, renewable sources of energy can act as a means of combating the Greenhouse Effect and of reducing the other environmental impacts of conventional energy technology, including the build-up of radioactive waste and the damaging emissions from fossil fuelled power stations. The UK has a large natural potential for harnessing energy from the wind (between 20% and 200% of our current electrical requirements). This potential is beginning to be tapped. Wind energy is now in a position where it can take advantage of the profound changes taking place in the form of the privatisation of the Electricity Supply Industry. In other countries wind energy has developed successfully. (author).

Reductions in the cost of producing wind energy are helping to make this renewable energy source competitive with conventional energy sources. The market for this type of energy in Italy, however, hasn't yet gained a foothold even though close examination of Italy's geomorphology reveals that this country is in fact endowed with many areas having good potential for wind power production. This paper discusses the measures to be taken to bolster wind energy commercialization efforts in Italy. It provides a brief assessment of the current state of wind power technology, national and international market trends, and the directions being taken by other national governments to promote wind turbine manufacturing industries and applications. The comparative analysis indicates that in order to have this energy source alternative taken seriously as an economically viable energy option in Italy, greater financial assistance should be given to local manufacturers involved in commercialization efforts. In addition, a suitable rate structure should be created favouring wind power by taking into account cost benefits afforded by this renewable energy source in terms of reduced air pollution, as well as, reduced national dependency on foreign energy imports

France is currently engaged in the energy transition where ambitious goals are at stake to allow the country to be one of the leading European countries in renewable energies. The cost of onshore wind is getting more and more competitive and for this reason, wind energy professionals are committed in contributing actively to reach the 32 % objective of renewable energies in the final energy consumption and 40 % of renewable energies in the electricity mix for 2030. 2014 was marked by a swift growth of the installed onshore wind energy, the positive trend is confirmed in 2015 with more than 500 MW connected to the grid in the first half of the year, corresponding to the annual forecast of 1,200 MW for 2015. Thanks to the energy transition law, operational policies will be implemented through the multi-annual energy programming (PPE- programmation pluriannuelle de l'energie). France will therefore continue increasing its development of renewable energies. This law will also allow France to develop offshore wind energy and to strengthen its position regarding wind energy: with an objective of 15 GW of fixed offshore wind energy and 6 GW of floating wind energy to be built in the 2030 horizon, the sector will be able to guarantee its development, especially in the current context of strong worldwide competition. Some 10,000 direct and indirect jobs are awaited for offshore wind energy on the national territory and wind energy professionals underline that the development of the offshore wind sector will contribute to the economic dynamism of the country. This sector is thus a job creating sector as confirmed in the figures of the wind employment monitor (observatoire de l'emploi) in France, recording a significant growth in 2013 with 10,800 jobs. This upward trend was confirmed in 2014. This proves the continuous commitment of the wind industry in seeing the success of the energy transition in France in a context marked by numerous energy and climate events

Government intervention in green industries: lessons from the wind turbine and the organic food industries in Denmark

. While the electricity market share of wind energy reached 20% in 2007, organic food consumption lags behind with a food market share of approximately 8.5% in 2007. This paper compares the packages of policy instruments applied in the two industrial sectors and assesses whether differences in instrument...... choice may explain the significant differences in market shares. It is demonstrated that government intervention in the wind turbine industry has emphasised the use of policy instruments designed to increase demand for wind energy, whereas organic farming policy has put more emphasis on instruments...... motivating farmers to increase supply. This may be an important factor explaining variance in growth. Finally, the paper analyses whether the lessons from government policy aimed at promoting the wind turbine industry can be transferred to organic farming policy....

This project developed relationships among the lead institution, U of Delaware, wind industry participants from 11 companies, and two other universities in the region. The participating regional universities were University of Maryland and Old Dominion University. Research was carried out in six major areas: Analysis and documentation of extreme oceanic wind events & their impact on design parameters, calibration of corrosivity estimates measured on a coastal turbine, measurment and modeling of tower structures, measurement and modeling of the tribology of major drive components, and gearbox conditioning monitoring using acoustic sensors. The project also had several educational goals, including establishing a course in wind energy and training graduate students. Going beyond these goals, three new courses were developed, a graduate certificate program in wind power was developed and approved, and an exchange program in wind energy was established with Danish Technical University. Related to the installation of a Gamesa G90 turbine on campus and a Gamesa-UD research program established in part due to this award, several additional research projects have been carried out based on mutual industry-university interests, and funded by turbine revenues. This award and the Gamesa partnership have jointly led to seven graduate students receiving full safety and climb training, to become “research climbers” as part of their wind power training, and contributing to on-turbine research. As a result of the educational program, already six graduate students have taken jobs in the US wind industry.

Issues concerning the social acceptance of wind energy are major challenges for policy-makers, communities and wind developers. They also impact the legitimacy of societal decisions to pursue wind energy. Here we set out to identify and assess the factors that lead to wind energy disputes in Ontario, Canada, a region of the world that has experienced a rapid increase in the development of wind energy. Based on our expertise as a group comprising social scientists, a community representative and a wind industry advocate engaged in the Ontario wind energy situation, we explore and suggest recommendations based on four key factors: socially mediated health concerns, the distribution of financial benefits, lack of meaningful engagement and failure to treat landscape concerns seriously. Ontario's recent change from a feed-in-tariff-based renewable electricity procurement process to a competitive bid process, albeit with more attention to community engagement, will only partially address these concerns.

With over 5, 660 MW installed in end-2010, France ranks fourth in Europe, behind Germany, Spain and Italy. The wind power industry currently employs almost 11, 000 people in France throughout the value chain. In 2009, the first edition of this directory listed over one hundred companies working in around twenty different areas. Encouraged by these initial positive results, and with the help of ADEME, the French syndicate for renewable energies (SER) asked Capgemini Consulting to undertake a study to identify and raise awareness among French industrials likely to enter into the wind energy market. The French Ministry for Ecology, Energy, Sustainable Development and the Sea, along with the Ministry for the Economy, Finance and Employment, were involved in the work. 400 companies were questioned as part of the study. Over 150 replies testified to the dynamic character of the wind power market in France and overseas, and the opportunities for diversification that it represents for traditional industries like metallurgy, aeronautics, defence and shipyards, etc. The study led to the creation of the initiative Windustry France, which currently groups over 300 companies either active in the French wind power market or set to enter it. Windustry France is a showcase of the industrial know-how that can be used in the wind power industry both onshore and offshore. It includes local set-ups developed around major fields of activity (e.g. car industry, aeronautics, mechanics, etc.) and industrial port zones (Dunkerque, Rouen/Le Havre, Brest, Nantes Saint-Nazaire, Bordeaux, etc.). Several ministries, regional stakeholders and authorities are also involved (local authorities, Regional directorates for industry, research and the environment (DReal) networks and chambers of commerce and industry), all of which contribute to making Windustry France a collective approach to industrial policy.

1997-07-01

The report describes the business plan for the establishment of a Wind Energy Centre in Gujarat. This Wind Energy Center has to provide a reliable delivery of a range of development and technical quality assurance services to the wind energy industry in northern India on the basis of sustained operations and recovery of all operating costs and - contingent on the way the Centre is financed - at least part of the initial investment costs. Core activities of the Wind Energy Centre are: Research and development supporting activities for the wind energy sector; Testing and certification of wind energy equipment; Consultancy, monitoring and information services; and Training courses on wind energy technology and implementation. The wind energy centre aims with its services at a number of customers: the manufacturing industry, wind farm developers and governmental authorities. An exploration of the market for the services of the envisaged wind energy centre shows that the concept is financially viable. A set of assumptions has been made about the growth rate of the installed wind power capacity in Northern India and about the number of wind turbine manufacturing companies in the target area of the centre. From these assumptions the total number of new wind turbine types coming on the Indian market annually is derived for a period of ten years. These figures have served as a basis for the determination of the required manpower and facilities of the centre for design and development support activities, feasibility and siting studies, testing and certification. Furthermore a projection has been made for providing expert manpower capacity for carrying out R and D, consultancy and other services. 14 tabs., 1 ref

The destiny of wind energy manufacturers

International Nuclear Information System (INIS)

Weller, Th.

1996-01-01

Today's market of wind energy manufacturers and its future development is analysed by use of a trend based scenario method, taking into account all future dynamics of the industry. The status quo of the industry is found to be fundamentally unstable and has already started to change its structure. Dependent on social acceptance of renewables and political behaviour (''conventional'' versus ''innovative'') four different extreme markets are described into which the development may go. Conclusions are drawn how to increase the probability of positive wind energy scenarios. Manufacturers of wind energy systems are categorised into four different groups: stars, problem children, dogs and cash cows. Each group is analysed based on its present market position, its innovative power and its capability to adapt to the requirements of the four considered ''futures''. The summary is that - wherever future developments will go - most of today's manufacturers will cease to exist in their present form, will leave the market, be merged into larger units or migrate to service providers.

The performance of thermal and nuclear power plants is assessed routinely and precisely, whereas the performance assessment of wind turbines is lagging far behind. This increases operational costs, reduces energy capture, and makes wind energy less competitive. The paper presents a technology and system with improved 24-h power forecasting, as well as condition monitoring of the rotor blades. The system can be employed by any wind power plant and offers potentials to increase the competitiveness of the power industry. (orig.)

Based on papers from Norway, Sweden, Spain and Denmark, submitted to the ECWEC'93 conference in Travemuende, Germany, and the draft 1992 annual report of the IEA R+D Wind Programme, a general review is given of national wind energy programmes in European countries. First, tendencies of the past wind energy programmes are described and linked to the present developments. Not only the separate aspects are reviewed (R+D, wind turbine development, market stimulation, utility involvement, regulatory issues and operational experiences), but also the synergetic aspects of their integration is addressed. The main conclusion is that the integration of R+D, industrial development and market stimulation works. 3 tabs

Concerns for potential wildlife impacts resulting from land-based and offshore wind energy have created challenges for wind project development. Research is not always adequately supported, results are neither always readily accessible nor are they satisfactorily disseminated, and so decisions are often made based on the best available information, which may be missing key findings. The potential for high impacts to avian and bat species and marine mammals have been used by wind project opponents to stop, downsize, or severely delay project development. The global nature of the wind industry - combined with the understanding that many affected species cross-national boundaries, and in many cases migrate between continents - also points to the need to collaborate on an international level. The International Energy Agency (IEA) Wind Technology Collaborative Programs facilitates coordination on key research issues. IEA Wind Task 34 - WREN: Working Together to Resolve Environmental Effects of Wind Energy-is a collaborative forum to share lessons gained from field research and modeling, including management methods, wildlife monitoring methods, best practices, study results, and successful approaches to mitigating impacts and addressing the cumulative effects of wind energy on wildlife.

International Nuclear Information System (INIS)

Wang, Zhongying; Qin, Haiyan; Lewis, Joanna I.

2012-01-01

Since 2005 the Chinese wind power technology industry has developed rapidly, with China becoming the largest installer of wind power capacity in the world in 2010. This paper reviews the policy system implemented in China to support the wind power industry, centered on China's 2005 Renewable Energy Law. It examines the industry's achievements over the past two decades, including the development of wind power technology and equipment, the utilization of China's wind power resources, and the cost reductions achieved. It then explores the obstacles affecting the ongoing sustainability of the Chinese wind industry, including regulatory barriers, grid integration challenges, and challenges to continued technological innovation. It recommends that integration challenges be addressed through policy reforms, establishing interconnection standards, and creating predictability with forecasting and storage; that market signals be established with long-term development goals and pricing reforms; and that industry limitations be addressed with targeted R and D, improved wind resource assessment and transparency, domestic and international collaborations, and the cultivation of a skilled workforce. - Highlights: ► Review the policy system and the achievements of Chinese wind industry. ► Analyze the obstacles affecting the sustainability of the industry. ► Provide recommendations for how China can address these obstacles.

The European renewable energy industry has the potential to be a world leader. This has been achieved within the European region for specific technologies, through a set of policy activities at a national and regional level, driven primarily by employment, energy self-sufficiency and industrial competitiveness. Using the experience gained in recent years, European industry has the opportunity to continue to expand its horizons on a worldwide level. Through the use of the SAFIRE rational energy model, an assessment has been made of the future penetration of renewable energy within Europe and the effects on these socio-economic factors. In conjunction with these outputs, assessments of the worldwide markets for wind, photovoltaics, solar thermal plant and biomass have been assessed. A case study of the Danish wind industry is used as a prime example of a success story from which the learning opportunities are replicated to other industries, so that the European renewable energy industry can achieve its potential.

Results presented in this report provide the first published investigation into the detailed makeup of the wind energy workforce, educational infrastructure and training needs of the wind industry. Insights from this research into the domestic wind workforce will allow the private sector, educational institutions, and federal and state governmental organizations to make workforce-related decisions based on the current employment and training data and future projections in this report.

Human resources challenges for wind energy

Energy Technology Data Exchange (ETDEWEB)

Cottingham, C. [Electricity Sector Council, Ottawa, ON (Canada)

2006-07-01

The potential role of the Electricity Sector Council in wind power workforce development was reviewed. Canada is a major exporter of electricity, and production of electricity in the country has grown by 10 per cent in the last 10 years. The electric industry has become increasingly interested in the development of renewable and sustainable energy sources in order to reduce the environmental impacts of electricity production and use, as well to address potential supply shortages. However, total labour force growth in Canada is expected to drop to 0.5 per cent by 2010, and is expected to keep falling. Engineering and science enrolments in post-secondary institutions are declining. Many immigrants to Canada choose to settle in metropolitan areas, and only 4 in 10 immigrants are able to achieve validation of their credentials in the Canadian education system. One-third of Canadian employees are expected to retire in the next 8 years. The wind energy sector is the fastest growing energy source sector in Canada, and there are limited training facilities available. Competency profiles for roles in the industry are not clearly defined. Many provinces have very little development to support or sustain educational services for wind power training. This presentation suggested that the wind energy sector should prepare for the anticipated workforce shortage by planning training programs and building partnerships in workforce development. Investments in wind power research and development should have contract provisions regarding labour and skills development. Retiring electricity workers may provide a source of labour support. Sector councils provide a neutral forum for employers, educators, and employees, with a focus on human resource development for specific industry sectors. The councils represent an estimated 45 to 50 per cent of the labour market, and have significant federal funding. The Electricity Sector Council offers advanced career and workforce training; youth

Oteri, F.

2008-12-01

Due to increased energy demand in the United States, rural communities with limited or no experience with wind energy now have the opportunity to become involved in this industry. Communities with good wind resources may be approached by entities with plans to develop the resource. Although these opportunities can create new revenue in the form of construction jobs and land lease payments, they also create a new responsibility on the part of local governments to ensure that ordinances will be established to aid the development of safe facilities that will be embraced by the community. The purpose of this report is to educate and engage state and local governments, as well as policymakers, about existing large wind energy ordinances. These groups will have a collection of examples to utilize when they attempt to draft a new large wind energy ordinance in a town or county without existing ordinances.

Wind energy is rapidly growing. In 2006 the installed generating capacity in the world increased by 25%, a growth rate which has more or less been sustained during the last decade. And there is no reason to believe that this growth will slow significantly in the coming years. For example, the United Kingdom's goal for installed wind turbines by 2020 is 33 GW up from 2 GW in 2006, an average annual growth rate of 22% over that period. More than half of all turbines are installed in Europe, but United States, India and lately China are also rapidly growing markets. The cradle of modern wind energy was set by innovative blacksmiths in rural Denmark. Now the wind provides more than 20% of the electrical power in Denmark, the industry has professionalized and has close ties with public research at universities. This focus issue is concerned with research in wind energy. The main purposes of research in wind energy are to: decrease the cost of power generated by the wind; increase the reliability and predictability of the energy source; investigate and reduce the adverse environmental impact of massive deployment of wind turbines; build research based educations for wind energy engineers. This focus issue contains contributions from several fields of research. Decreased costs cover a very wide range of activities from aerodynamics of the wind turbine blades, optimal site selection for the turbines, optimization of the electrical grid and power market for a fluctuating source, more efficient electrical generators and gears, and new materials and production techniques for turbine manufacturing. The United Kingdom recently started the construction of the London Array, a 1 GW off-shore wind farm east of London consisting of several hundred turbines. To design such a farm optimally it is necessary to understand the chaotic and very turbulent flow downwind from a turbine, which decreases the power production and increases the mechanical loads on other nearby turbines.

Over the past 30 years, wind power has become a mainstream source of electricity generation around the world. However, the future of wind power will depend a great deal on the ability of the industry to continue to achieve cost of energy reductions. In this summary report, developed as part of the International Energy Agency Wind Implementing Agreement Task 26, titled 'The Cost of Wind Energy,' we provide a review of historical costs, evaluate near-term market trends, review the methods used to estimate long-term cost trajectories, and summarize the range of costs projected for onshore wind energy across an array of forward-looking studies and scenarios. We also highlight the influence of high-level market variables on both past and future wind energy costs.

Wind energy developments in the Americas

This paper will highlight the key wind energy activities and programs of American countries. In South and Central America, wind technology awareness and opportunity is spreading. Countries have projects in the beginning stages of development and many sites with excellent wind resources are believed to exist. Argentina, Costa Rica, Colombia, Mexico, and several Caribbean countries are among those active in wind energy development. In Canada, after a decade of research and systems development, the Department of Energy Mines and Resources is conducting a review of all renewable energy technologies, including wind, to develop a strategic plan for future activities. Canadian industry continues development of various vertical axis projects and the Province of Alberta has begun a program to assess wind potential in that region. In the United States, commercial application of wind energy is continuing to expand. During 1989, over 140 MW of new wind turbine capacity was installed in wind power plants, bringing the total operating in the U.S. to 14600 turbines and 1,400 MW. During 1989, these machines produced over 2.1 billion kWh, enough to supply the residential needs of Washington D.C. or San Francisco. This is an increase of 15% over the 1988 total, even though installed operating capacity dropped by about 10% as smaller, out-dated turbines were phased out or replaced. The U.S. government is in the process of formulating a new National Energy Strategy. It seems clear that renewable energy and energy efficiency will play an increasingly important role in this strategy. The U.S. wind program continues to emphasize broad-based technology development, but has also initiated conceptual design studies for an advanced wind turbine for power generation in the late 1990s.

Toward Robust and Efficient Climate Downscaling for Wind Energy

Science.gov (United States)

Vanvyve, E.; Rife, D.; Pinto, J. O.; Monaghan, A. J.; Davis, C. A.

2011-12-01

This presentation describes a more accurate and economical (less time, money and effort) wind resource assessment technique for the renewable energy industry, that incorporates innovative statistical techniques and new global mesoscale reanalyzes. The technique judiciously selects a collection of "case days" that accurately represent the full range of wind conditions observed at a given site over a 10-year period, in order to estimate the long-term energy yield. We will demonstrate that this new technique provides a very accurate and statistically reliable estimate of the 10-year record of the wind resource by intelligently choosing a sample of ±120 case days. This means that the expense of downscaling to quantify the wind resource at a prospective wind farm can be cut by two thirds from the current industry practice of downscaling a randomly chosen 365-day sample to represent winds over a "typical" year. This new estimate of the long-term energy yield at a prospective wind farm also has far less statistical uncertainty than the current industry standard approach. This key finding has the potential to reduce significantly market barriers to both onshore and offshore wind farm development, since insurers and financiers charge prohibitive premiums on investments that are deemed to be high risk. Lower uncertainty directly translates to lower perceived risk, and therefore far more attractive financing terms could be offered to wind farm developers who employ this new technique.

Circular economy opportunity in the wind industry. Final report

2015-05-01

The objective of this study is to identify how the circular economy can be an opportunity for the French wind industry. A broad review of circular economy issues for the wind industry value chain has been conducted in order to be used as a decision making tool for ADEME and the wind industry stakeholders. First of all, a 'flow analysis' (including material, logistic and services related to wind power) has been carried out in order to highlight the specific challenges of circular economy for the wind sector. The strategic opportunities that meet these issues have then been identified. A selection of six opportunities has been further investigated to assess the benefits, to analyze the barriers and to identify actions that ADEME could initiate to foster these opportunities. These investigated opportunities are the following: - To structure a recycling chain for wind blades; - To promote the business model of the extension of wind turbine's lifetime; - To promote skills improvement of local providers for reconditioning and maintenance services; - To adapt the offshore hubs to integrate dismantling activity of onshore equipments; - To increase the manufacturing capacity of wind towers in France to increase local sourcing; - To encourage the creation of a leading French manufacturer to optimize the supply chain. In the light of this analysis, it can be concluded that circular economy represents a strategic opportunity for the French wind energy sector. The opportunities we focused on make up a consistent set of initiatives that improve the environmental, economic and social performance of the wind energy sector by strengthening industrial activities and services throughout all the life cycle: manufacturing stage (optimization of logistics flows and local manufacturing), use phase (maintenance, repair) and end-of-life phase of wind turbine (dismantling, recycling). While the sector has so far been focused on better solving technological challenges and

This report is a valuable tool for members of the wind industry and policy makers alike to learn about the market opportunities and the legal and regulatory framework in India. In addition, it gives us insights into the challenges going forward and offers suggestions for overcoming remaining hurdles for wind power development. According to the outlook 65.2 GW of wind power could be installed in Indian by 2020, up from 13.1 GW at the end of 2010. This would attract around USD 10.4bn of annual investment to the sector, and create 170,000 'green collar' jobs in manufacturing, project development, installation, operation, maintenance, consulting etc. At the same time, it would save 174 tons of CO2 every year. By 2030, the installed capacity could reach as much as 160.7 GW. In order to fully exploit the indigenous energy source at its doorstep, the Indian government needs to address several challenges and barriers that are holding back development. This includes a national renewable energy law, incentives for repowering, and rapid up-scaling of grid infrastructure to transport increasing amounts of wind power to the demand centres. It highlights the key role wind power could play in fueling India's growing energy demand, by delivering substantial amounts of clean energy.

Wind power is an inexhaustible form of energy that is being captured throughout the U.S. to power the engine of our economy. A robust, domestic wind industry promises to increase U.S. industry growth and competitiveness, strengthen U.S. energy security independence, and promote domestic manufacturing nationwide. As of 2016, ~82GW of wind capacity had been installed, and wind power now provides more than 5.5% of the nation’s electricity and supports more than 100,000 domestic jobs, including 500 manufacturing facilities in 43 States. To reach the U.S. Department of Energy’s (DOE’s) 2015 Wind Vision study scenario of wind power serving 35% of the nation's end-use demand by 2050, significant advances are necessary in all areas of wind technologies and market. An area that can greatly impact the cost and rate of innovation in wind technologies is the use of advanced manufacturing, with one of the most promising areas being additive manufacturing (AM). Considering the tremendous promise offered by advanced manufacturing, it is the purpose of this report to identify the use of AM in the production and operation of wind energy systems. The report has been produced as a collaborative effort for the DOE Wind Energy Technology Office (WETO), between Oak Ridge National Laboratory (ORNL) and the National Renewable Energy Laboratory (NREL).

Progress and plans for wind energy in the United States

Under its wind energy research and development program, the U.S. Department of Energy (DOE) works as a partner with industry to improve understanding of wind system technology and to develop and deploy advanced wind turbines in multi-regional markets. Installed capacity in the U.S. reached 1770 MW by the end of 1995. However, this figure does not include some capacity that was retired or brought off line. Growth of about 140 MW during 1995, is attributed to improved and lower cost turbines and was stimulated in part by the availability of energy tax credits and production and financial incentives. In addition, there are nearly 500 MW of firm contracts for new domestic wind plants. Recently, there has been substantial growth in both Europe and the rest of the world, those countries other than Europe and the U.S. The U.S. DOE Wind Energy Systems Program is continuing broad based research and technology development focusing on advanced wind turbine development. Contracts have been placed with industry for next generation design studies, innovative subsystems applied research, and value engineering to improve existing turbines. Some of these turbines are now being deployed in utility verification projects. Over the past year, the U.S. opened its National Wind Technology Center, located near Golden, Colorado. The center will include a new user facility to serve as a wind turbine blade and system testing and research center for industry. (author)

Prospects for a wind pump industry in Sri Lanka

Fernando, S.

1991-01-01

Since 1977 considerable effort has been made in Sri Lanka to develop and disseminate wind pumping systems primarily in the small-scale agricultural sector in the island's dry zone. Through close cooperation with the Consultancy Services Wind Energy Developing Countries (CWD) in the Netherlands this programme has been successful in developing the necessary hardware but the broad objective of promoting wide spread use of wind pumping in Sri Lanka is yet to materialize. In analyzing probable reasons for this, the paper highlights that the basic arguments underlying the origin of the project in 1976, such as foreign exchange savings and local industrial development, became irrelevant to the post 1977 political and economic policies of the new government. Thus, the general economic framework adopted in Sri Lanka since 1977 does not seem to provide the necessary pre-conditions for development of a local industry for wind pumps. Due to this reason and the fact that kerosene oil used in conventional agriculturla pumps is subsidized, the ability of wind pumps to compete in the wind pump market seems highly constrained. It is concluded that under such conditions the prospects for the manufacturing and marketing of wind pumps on an industrial scale are not very favourable

The purpose of this guideline is to establish a clear and consistent vocabulary for conveying offshore wind resource potential and to interpret this vocabulary in terms that are familiar to the oil and gas (O&G) industry. This involves clarifying and refining existing definitions of offshore wind energy resource classes. The terminology developed in this guideline represents one of several possible sets of vocabulary that may differ with respect to their purpose, data availability, and comprehensiveness. It was customized to correspond with established offshore wind practices and existing renewable energy industry terminology (e.g. DOE 2013, Brown et al. 2015) while conforming to established fossil resource classification as best as possible. The developers of the guideline recognize the fundamental differences that exist between fossil and renewable energy resources with respect to availability, accessibility, lifetime, and quality. Any quantitative comparison between fossil and renewable energy resources, including offshore wind, is therefore limited. For instance, O&G resources are finite and there may be significant uncertainty associated with the amount of the resource. In contrast, aboveground renewable resources, such as offshore wind, do not generally deplete over time but can vary significantly subhourly, daily, seasonally, and annually. The intent of this guideline is to make these differences transparent and develop an offshore wind resource classification that conforms to established fossil resource classifications where possible. This guideline also provides methods to quantitatively compare certain offshore wind energy resources to O&G resource classes for specific applications. Finally, this guideline identifies areas where analogies to established O&G terminology may be inappropriate or subject to misinterpretation.

Innovation and the price of wind energy in the US

International Nuclear Information System (INIS)

Berry, David

2009-01-01

In the last ten years, the wind energy industry has experienced many innovations resulting in wider deployment of wind energy, larger wind energy projects, larger wind turbines, and greater capacity factors. Using regression analysis, this paper examines the effects of technological improvements and other factors on the price of wind energy charged under long-term contracts in the United States. For wind energy projects completed during the period 1999-2006, higher capacity factors and larger wind farms contributed to reductions in wind energy contract prices paid by regulated investor owned utilities in 2007. However, this effect was offset by rising construction costs. Turbine size (in MW) shows no clear relationship to contract prices, possibly because there may be opposing factors tending to decrease costs as turbine size increases and tending to increase costs as turbine size increases. Wind energy is generally a low-cost resource that is competitive with natural gas-fired power generation.

In January 2010, the University of Minnesota, along with academic and industry project partners, began work on a four year project to establish new facilities and research in strategic areas of wind energy necessary to move the nation towards a goal of 20% wind energy by 2030. The project was funded by the U.S. Department of Energy with funds made available through the American Recovery and Reinvestment Act of 2009. $7.9M of funds were provided by DOE and $3.1M was provided through matching funds. The project was organized into three Project Areas. Project Area 1 focused on design and development of a utility scale wind energy research facility to support research and innovation. The project commissioned the Eolos Wind Research Field Station in November of 2011. The site, located 20 miles from St. Paul, MN operates a 2.5MW Clipper Liberty C-96 wind turbine, a 130-ft tall sensored meteorological tower and a robust sensor and data acquisition network. The site is operational and will continue to serve as a site for innovation in wind energy for the next 15 years. Project Areas 2 involved research on six distinct research projects critical to the 20% Wind Energy by 2030 goals. The research collaborations involved faculty from two universities, over nine industry partners and two national laboratories. Research outcomes include new knowledge, patents, journal articles, technology advancements, new computational models and establishment of new collaborative relationships between university and industry. Project Area 3 focused on developing educational opportunities in wind energy for engineering and science students. The primary outcome is establishment of a new graduate level course at the University of Minnesota called Wind Engineering Essentials. The seminar style course provides a comprehensive analysis of wind energy technology, economics, and operation. The course is highly successful and will continue to be offered at the University.

2012-12-18

DNV Renewables (USA) Inc. (DNV KEMA) received a grant from the U.S. Department of Energy (DOE) to develop the curriculum for a series of short courses intended to address Topic Area 5 Workforce Development, one of the focus areas to achieve the goals outlined in 20% Wind by 2030: Increasing Wind Energy's Contribution to Electricity Supply. The aim of the curriculum development project was to provide material for instructors to use in a training program to help professionals transition into careers in wind energy. Under this grant DNV KEMA established a knowledge boosting program for the wind energy industry with the following objectives: 1. Develop technical training curricula and teaching materials for six key topic areas that can be implemented in a flexible format by a knowledgeable instructor. The topic areas form a foundation that can be leveraged for subsequent, more detailed learning modules (not developed in this program). 2. Develop an implementation guidance document to accompany the curricula outlining key learning objectives, implementation methods, and guidance for utilizing the curricula. This curriculum is intended to provide experienced trainers course material that can be used to provide course participants with a basic background in wind energy and wind project development. The curriculum addresses all aspects of developing a wind project, that when implemented can be put to use immediately, making the participant an asset to U.S. wind industry employers. The curriculum is comprised of six short modules, together equivalent in level of content to a one-semester college-level course. The student who completes all six modules should be able to understand on a basic level what is required to develop a wind project, speak with a reasonable level of confidence about such topics as wind resource assessment, energy assessment, turbine technology and project economics, and contribute to the analysis and review of project information.

2009-01-01

Wind power in China registered a record level of expansion recently, and has doubled its total capacity every year since 2004. Many experts believe that China will be central to the future of the global wind energy market. Consequently, the growth pattern of wind power in China may be crucial to the further development of the global wind market. This paper firstly presented an overview of wind energy potential in China and reviewed the national wind power development course in detail. Based on the installed wind capacity in China over the past 18 years and the technical potential of wind energy resources, the growth pattern was modeled in this study for the purpose of prospect analysis, in order to obtain projections concerning the development potential. The future perspectives of wind energy development in China are predicted and analyzed. This study provides a comprehensive overview of the current status of wind power in China and some insights into the prospects of China's wind power market, which is emerging as a new superpower in the global wind industry.

Templin, R.J.; Rangli, R.S.

1992-01-01

The current status of wind energy technology in Canada is reviewed, the technical potential of wind energy in Canada is estimated, and the economic market potential is assessed under several scenarios over about the next 25 years. The technical potential is seen to be large, with applications to water pumping on farms, the coupling of wind turbines to diesel-electric systems in remote communities where fuel costs are high, and the supply of electricity to main power grids. The main-grid application has greatest technical potential, but it cannot be economically exploited under the present utility buyback rate structure for intermittent power sources. A change in government policy toward market development of renewable energy sources, such as is already taking place in several European countries, would greatly increase market potential, decrease emissions of CO 2 and SO 2 , and benefit the Canadian wind energy industry. 2 figs., 1 tab

This report is a valuable tool for members of the wind industry and policy makers alike to learn about the market opportunities and the legal and regulatory framework in India. In addition, it gives us insights into the challenges going forward and offers suggestions for overcoming remaining hurdles for wind power development. According to the outlook 65.2 GW of wind power could be installed in Indian by 2020, up from 13.1 GW at the end of 2010. This would attract around USD 10.4bn of annual investment to the sector, and create 170,000 'green collar' jobs in manufacturing, project development, installation, operation, maintenance, consulting etc. At the same time, it would save 174 tons of CO2 every year. By 2030, the installed capacity could reach as much as 160.7 GW. In order to fully exploit the indigenous energy source at its doorstep, the Indian government needs to address several challenges and barriers that are holding back development. This includes a national renewable energy law, incentives for repowering, and rapid up-scaling of grid infrastructure to transport increasing amounts of wind power to the demand centres. It highlights the key role wind power could play in fueling India's growing energy demand, by delivering substantial amounts of clean energy.

Offshore wind energy, who will risk investment?

International Nuclear Information System (INIS)

Dupin, Ludovic; Moragues, Manuel

2013-01-01

As Europe plans to install 40 GW of offshore wind energy production by 2020 and only 5 GW are already installed, investment is a crucial issue for a still immature industry and in a context where risk management is critical, notably during construction (harsh working conditions, costs of construction, of maintenance and costs related to delays). Other aspects are also related to financial risks like, for example, the cost of offshore wind farm connection to the grid (this has been an underestimated issue in Germany). Then operation and exploitation have to face climate events although, according to relatively recent exploitation data, availability is quite good. The durability of political support is not so sure in a context of political and regulatory instability and of economic crisis. In France, after the first bidding, the wind energy industrial sector is emerging and many small and medium companies enter this activity in the trail of Areva and Alstom, with thousands of job creations and export perspectives. Some offshore wind turbines are briefly presented (by Alstom, Areva, RE Power, Siemens and Vestas)

2010-01-01

The wind power industry is now experiencing rapid growth in many of the developed countries who seek to expand their renewable energy portfolios and reduce harmful emissions into the atmosphere. The annual Canadian Wind Energy Association (CanWEA) conference and exhibition provides a forum for members of the wind power industry as well as various other experts and stakeholders to exchange information and to discuss innovations and technologies designed to increase wind power capacity in Canada. The environmental impacts of wind turbines were examined, as well as some of the issues that are currently inhibiting growth of the wind power industry. New construction and operational strategies were presented. Business approaches for ensuring adequate investment in the industry were reviewed, and recommendations for government regulations and renewable energy investment incentives were provided. Advances in forecasting were outlined, and issues currently influencing the electric power industry in relation to wind power, reliability, and growth were also discussed. Methods of ensuring the reliability and safety of turbines in the event of icing and other meteorological events were also presented. The conference was divided into the following 5 tracks over a 3 day period: (1) project assessment, (2) project development, (3) business development, (4) technical, and (5) small wind. Each track was further sub-divided into sessions that covered a range of topics. Twenty-nine presentations were included in a poster session. The conference featured 118 presentations, of which 108 have been catalogued separately for inclusion in this database. refs., tabs.

Following the request for proposal (RFP)-fueled explosion in renewable energy source development over the past 3 years, independent power producer (IPP) financial expertise has become critical to successful project implementation. This presentation reviewed aspects of Canadian wind market related to independent power producer (IPP) investment activity. A map of major Canadian wind farms operational at the end of 2005 was provided, as well as a map of provinces with utility RFP activity. Planned projects were listed by MW. Recent provincial RFP winners were listed. It was suggested that project execution experience and financial security were highly valued in the recent Hydro-Quebec and Ontario RFP solicitations. Developer consolidation and scaling is likely to continue as large wind IPPs are in the best position to maximize efficiency gains in project economics. Financial strength will continue to be key to winning provincial wind RFPs, and Quebec and Ontario RFPs are likely to be dominated by players with balance sheet security. Smaller developers are losing their competitive position in RFP negotiations as more national and international energy giants move into the wind industry. The consolidation trend is ramping up quickly, and may be closing the window in which international investors can find acquisition targets with experience and viable projects. It was concluded that while small developers with robust projects still exist, they are being acquired at a rapid rate. refs., tabs., figs

In Denmark, wind energy makes a visible contribution to energy planning. Since 1976, over 1,800 wind turbine units have been installed in Denmark, representing a capacity of ca 140 MW out of a grid capacity of 8,000 MW. These units are all grid-connected and the unit sizes range from 55 kW to 400 kW. The installed wind energy capacity represents a substantial development of technologies for wind energy utilization during the last 15 years, involving participation from research institutes, electric utilities, private industry, and the national energy administration. A considerable improvement of the technical and economic performance of wind turbines, along with increased reliability and durability, has been strongly supported by comprehensive government programs. In 1985, another large construction program was initiated which will add 100 MW wind power capacity by the end of 1990. Parallel with commercial development, Danish utilities have developed and constructed a number of megawatt-size wind turbines on a pilot basis. In general terms the wind energy resources in Denmark are rather good, and many suitable sites exist, but installed wind energy capacity is limited by the high population density. Consequently, research is being conducted on the feasibility of offshore wind turbines. In other countries, wind energy developments similar to those in Denmark are taking place. In communities with no connection to the national grid, special attention should be paid to hybrid systems such as wind-diesel and hydro-wind systems. A substantial transfer of technology is required for facilitating significant development of hybrid systems in developing countries. 11 refs., 7 figs., 2 tabs

Academics, practitioners, and policy makers continue to debate the benefits and costs of alternative sources of energy. Environmental and economic concerns have yet to be fully reconciled. One view is that decisions that incorporate both society's concern with the environment and investors' desire for shareholder value maximization are more likely to be truly sustainable. We coin the term dual sustainability to mean the achievement of environmental and financial sustainability simultaneously. Many experts believe that wind energy can help to meet society's needs without harming future generations. It is clean and renewable. Because the fuel is free it provides the ultimate in energy independence. Wind energy has emerged as a leading prospect, in part, because it is considered by many to be environmentally sustainable. However, a key question that remains is whether wind energy is financially sustainable without the extensive government support that has helped to create and nurture this growth industry. Using reliable, proprietary data from field research, our analysis employs a capital budgeting framework to evaluate the financial economics of investments in wind energy. We find that because of the convergence of improved technology, greater efficiency, and with the increasing cost of traditional, competing sources such as oil and natural gas, wind energy is close to becoming self-sustaining financially without the extensive federal government support that exists today. Wind energy can provide the best of both worlds. It is sustainable from an environmental perspective and it is becoming sustainable financially. In short, those companies investing in wind energy will be able to do well by doing good. Perhaps the achievement of dual sustainability is true sustainability. Our research findings and dual sustainability have several interesting and important implications for public policy towards wind energy. All imply that public policy can now be

From its rebirth in the early 1980s, the rate of development of wind energy has been dramatic. Today, other than hydropower, it is the most important of the renewable sources of power. The UK Government and the EU Commission have adopted targets for renewable energy generation of 10 and 12% of consumption, respectively. Much of this, by necessity, must be met by wind energy. The US Department of Energy has set a goal of 6% of electricity supply from wind energy by 2020. For this potential to be fully realized, several aspects, related to public acceptance, and technical issues, related to the expected increase in penetration on the electricity network and the current drive towards larger wind turbines, need to be resolved. Nevertheless, these challenges will be met and wind energy will, very likely, become increasingly important over the next two decades. An overview of the technology is presented.

Among the renewable energies, wind energy has gained the rapidest development in China. Moreover wind power generation has been penetrated into power system in a large scale. However, the high level wind curtailment also indicates a low efficiency of wind energy utilization over the last decade in China. One of the primary constraints on the utilization of wind energy is the lack of an electricity market, in which renewable energies can compete equally with traditional fossil fuel generation. Thus the new round electric power industry reform is essential in China. The reform involves implementing new pricing mechanism, introducing retail-side competition, promoting the consumption of renewable energy. The new round reform can be a promising solution for promoting the development and consumption of wind energy generation in China. Based on proposed reform policies of electric power industry, this paper suggests a roadmap for retail electricity market reform of China, which consists of three stages. Barriers to the efficient utilization of wind energy are also analysed. Finally, this paper introduces several efficient measures for mitigating wind curtailment in each stage of reform.

Scheduled to be published on an annual basis, it relies on both market and modeled data to maintain a current understanding of wind generation cost trends and drivers. It is intended to provide insight into current component-level costs and a basis for understanding current component-level costs and a basis for understanding variability in the LCOE across the industry. Data and tools developed from this analysis are used to inform wind technology cost projections, goals, and improvement opportunities.

From technology transfer to local manufacturing: China's emergence in the global wind power industry

Science.gov (United States)

Lewis, Joanna Ingram

This dissertation examines the development of China's large wind turbine industry, including the players, the status of the technology, and the strategies used to develop turbines for the Chinese market. The primary goals of this research project are to identify the models of international technology transfer that have been used among firms in China's wind power industry; examine to what extent these technology transfers have contributed to China's ability to locally manufacture large wind turbine technology; and evaluate China's ability to become a major player in the global wind industry. China is a particularly important place to study the opportunities for and dynamics of clean energy development due to its role in global energy consumption. China is the largest coal consuming and producing nation in the world, and consequently the second largest national emitter of carbon dioxide after only the United States. Energy consumption and carbon emissions are growing rapidly, and China is expected to surpass the US and become the largest energy consuming nation and carbon dioxide emitter in coming decades. The central finding of this dissertation is that even though each firm involved in the large wind turbine manufacturing industry in China has followed a very different pathway of technology procurement for the Chinese market, all of the firms are increasing the utilization of locally-manufactured components, and many are doing so without transferring turbine technology or the associated intellectual property. Only one fully Chinese-owned firm, Goldwind, has succeeded in developing a commercially available large wind turbine for the Chinese market. No Chinese firms or foreign firms are manufacturing turbines in China for export overseas, though many have stated plans to do so. There already exists a possible niche market for the smaller turbines that are currently being made in China, particularly in less developed countries that are looking for less expensive

Public acceptability of California's wind energy developments: three studies

Energy Technology Data Exchange (ETDEWEB)

Bosley, P.; Bosley, K.

1988-01-01

Qualitative and quantitative research was conducted during 1988 to determine perceptions and attitudes regarding wind energy development as held by government and regulatory officials involved with windfarm development in the three major wind resource regions in California; environmentalists and community activists in these regions; and members of the wind industry. Results indicate that realization of large windfarm projects is being affected by local opposition which exists partly because of lack of knowledge about the technical maturity and economics of today's windpower; opposed interests between the developers and the locality; and development-created problems such as ''Visual Intrusion''. Public acceptability, essential for industry success, may be hindered because wind energy benefits to a locality are not perceived to equal the risks incurred by that particular region. Therefore, the industry needs to continue improving its performance as well as its communications with all affected parties.

Wind energy. To produce electricity with the wind

Bareau, Helene

2015-11-01

This guide addresses the different aspects of wind-based power generation. It outlines the role of wind energy to meet objectives related to the share of renewable energies in the French energy mix, that wind energy is actually replacing fossil energies, that it is based on local resources within higher safety and less wastage, that current advances are made to integrate wind energy production into the grid, and that it is a solution to diversify energy production. Some figures are presented and commented, regarding onshore wind energy production in France, the location of wind farms, and wind energy production in comparison with other renewable sources. The operation of a wind turbine is described and the different types of wind turbines are evoked. The issue of wind farm planning with citizen participation is addressed: regional planning, studies of pre-feasibility for location selection, procedure, and content of the impact study (radars, fauna and flora, landscapes, safety, health). Other features are outlined: a planned dismantling, and a globally favourable perception. The next part addresses offshore wind energy: the interesting potential of stronger and more reliable wind at sea (European situation, French opportunities, elements comprised in an offshore wind farm), impacts (on marine ecosystems, on neighbouring localities, and interests for visitors). Economic aspects are then addressed: cost and profitability, economic spin-offs, and perspectives. The last part concerns individuals and the possibilities to participate to wind farm projects or to invest in small wind turbines with some prerequisites (constant and steady winds, installation assessment, required expertise, indispensable preliminary steps, costs, aids and profitability)

2014-01-01

As a new and developing green energy business in emerging economies such as China, the wind power industry chain faces some complex issues that are further compounded by turbulent internal and external environments. To deal with the complex environment, the wind power industry needs to improve its level of flexibility so that it can become more adaptable to the changing environment. Hence it is important to explore the dynamics of the wind power industry chain flexibility with respect to the ever changing environment. This study uses questionnaire surveys and expert interviews to identify the influential flexibility components of the wind power industry chain. Subsequently a fuzzy cognitive mapping (FCM) methodology was used to establish a flexibility operating mechanism model. The research found that special attention should be paid to competition flexibility, technology flexibility, and intellectual property and talent flexibility. Policies play a pivotal role in regulating the driving effects of these components of flexibility with the aim being long term sustainability of a healthy level of overall flexibility of the wind power industry chain. This should in turn facilitate the sustainable development of the industry. - Highlights: • Wind power industry shall improve flexibility to deal with complex environment. • Critical components of flexibility of wind power industry chain were identified. • An operating mechanism model for flexibility of wind power industry is proposed. • Fuzzy cognitive mapping method is employed to model the dynamics of flexibility. • Policies play a pivotal role in fostering an industry environment toward flexibility

The resilience of Australian wind energy to climate change

2018-02-01

The Paris Agreement limits global average temperature rise to 2 °C and commits to pursuing efforts in limiting warming to 1.5 °C above pre-industrial levels. This will require rapid reductions in the emissions of greenhouse gases and the eventual decarbonisation of the global economy. Wind energy is an established technology to help achieve emissions reductions, with a cumulative global installed capacity of ~486 GW (2016). Focusing on Australia, we assess the future economic viability of wind energy using a 12-member ensemble of high-resolution regional climate simulations forced by Coupled Model Intercomparison Project (CMIP) output. We examine both near future (around 2030) and far future (around 2070) changes. Extractable wind power changes vary across the continent, though the most spatially coherent change is a small but significant decrease across southern regions. The cost of future wind energy generation, measured via the Levelised Cost of Energy (LCOE), increases negligibly in the future in regions with significant existing installed capacity. Technological developments in wind energy generation more than compensate for projected small reductions in wind, decreasing the LCOE by around 30%. These developments ensure viability for existing wind farms, and enhance the economic viability of proposed wind farms in Western Australian and Tasmania. Wind energy is therefore a resilient source of electricity over most of Australia and technological innovation entering the market will open new regions for energy production in the future.

This paper surveys the landscape of systems engineering methods and current wind modeling capabilities to assess the potential for development of a systems engineering to wind energy research, design, and development. Wind energy has evolved from a small industry in a few countries to a large international industry involving major organizations in the manufacturing, development, and utility sectors. Along with this growth, significant technology innovation has led to larger turbines with lower associated costs of energy and ever more complex designs for all major subsystems - from the rotor, hub, and tower to the drivetrain, electronics, and controls. However, as large-scale deployment of the technology continues and its contribution to electricity generation becomes more prominent, so have the expectations of the technology in terms of performance and cost. For the industry to become a sustainable source of electricity, innovation in wind energy technology must continue to improve performance and lower the cost of energy while supporting seamless integration of wind generation into the electric grid without significant negative impacts on local communities and environments. At the same time, issues associated with wind energy research, design, and development are noticeably increasing in complexity. The industry would benefit from an integrated approach that simultaneously addresses turbine design, plant design and development, grid interaction and operation, and mitigation of adverse community and environmental impacts. These activities must be integrated in order to meet this diverse set of goals while recognizing trade-offs that exist between them. While potential exists today to integrate across different domains within the wind energy system design process, organizational barriers such as different institutional objectives and the importance of proprietary information have previously limited a system level approach to wind energy research, design, and

Thabit, S. S.; Stark, J.

This paper investigates the impact of the provisions of the new Energy Act, 1983 on industrial wind-powered private generators of electricity and the effects of published tariffs on various industrial working patterns. Up to 30 percent savings can be achieved in annual electricity bill costs for an industrial generator/user of electricity working a single daily shift, if located in a favorable, 7 m/s mean annual wind speed regime. Variation of the availability charge between Electricity Boards about a base value of 0.70 pounds sterling/kVA was found to have insignificant (+ or - 1.3 percent) impact on total electricity bill costs. It was also shown that for industrial users of electricity, the simpler two-rate purchase terms were commercially adequate when compared with the four-rate alternative where expensive metering becomes necessary.

A new remote sensing based research infrastructure for atmospheric boundary-layer wind and turbulence measurements named WindScanner have during the past three years been in its early phase of development at DTU Wind Energy in Denmark. During the forthcoming three years the technology will be disseminated throughout Europe to pilot European wind energy research centers. The new research infrastructure will become an open source infrastructure that also invites collaboration with wind energy related atmospheric scientists and wind energy industry overseas. Recent achievements with 3D WindScanners and spin-off innovation activity are described. The Danish WindScanner.dk research facility is build from new and fast-scanning remote sensing equipment spurred from achievements within fiber optics and telecommunication technologies. At the same time the wind energy society has demanded excessive 3D wind flow and ever taller wind profile measurements for the wind energy resource assessment studies on- and off shore of the future. Today, hub heights on +5 MW wind turbines exceed the 100 m mark. At the Danish DTU test site Oesterild testing is ongoing with a Siemens turbine with hub height 120 meters and a rotor diameter of 154 meters; hence its blade tips reaches almost 200 meters into the sky. The wind speed profiles over the rotor planes are consequently no longer representatively measured by a single cup anemometer at hub height from a nearby met-mast; power curve assessment as well as turbine control call for multi-height multi point measurement strategies of wind speed and wind shear within the turbines entire rotor plane. The development of our new remote sensing-based WindScanner.dk facility as well as the first measurement results obtained to date are here presented, including a first wind lidar measurement of turbulence in complex terrain within an internal boundary layer developing behind an escarpment.

Wind Energy Development in India and a Methodology for Evaluating Performance of Wind Farm Clusters

Directory of Open Access Journals (Sweden)

2016-01-01

Full Text Available With maturity of advanced technologies and urgent requirement for maintaining a healthy environment with reasonable price, India is moving towards a trend of generating electricity from renewable resources. Wind energy production, with its relatively safer and positive environmental characteristics, has evolved from a marginal activity into a multibillion dollar industry today. Wind energy power plants, also known as wind farms, comprise multiple wind turbines. Though there are several wind-mill clusters producing energy in different geographical locations across the world, evaluating their performance is a complex task and is an important focus for stakeholders. In this work an attempt is made to estimate the performance of wind clusters employing a multicriteria approach. Multiple factors that affect wind farm operations are analyzed by taking experts opinions, and a performance ranking of the wind farms is generated. The weights of the selection criteria are determined by pairwise comparison matrices of the Analytic Hierarchy Process (AHP. The proposed methodology evaluates wind farm performance based on technical, economic, environmental, and sociological indicators. Both qualitative and quantitative parameters were considered. Empirical data were collected through questionnaire from the selected wind farms of Belagavi district in the Indian State of Karnataka. This proposed methodology is a useful tool for cluster analysis.

Wind energy systems and their potential in the UK

Energy Technology Data Exchange (ETDEWEB)

Musgrove, P

1977-01-01

Wind Energy systems have the potential to provide at least one quarter of our present electricity requirements. The UK has much relevant technological experience, in its Aerospace and Engineering Industry, and if a Wind Energy research and development programme were adequately funded, we could start to produce significant quantities of wind generated electricity in little more than a decade. Preliminary cost studies indicate that even at today's fuel prices, wind generated electricity is very close to being economically viable. Given the expectation that the demand for oil will exceed available supplies within the next decade, and the knowledge that present reserves of oil and gas will be largely depleted within the next generation, large increases in the real cost of fossil fuels must be anticipated in the near future. These expected fuel cost increases provide the economic justification for developing and deploying wind energy systems as rapidly as possible.

Wind energy development in the light of Danish experiences

Frandsen, S.

1991-01-01

Wind energy will undoubtedly play a significant role in the future energy supply being a nonpolluting energy source, which on a technical basis has proved to be an economically feasible and thus a realistic alternative to traditional power production. This conclusion may be drawn from Danish experiences where energy planning comprises a visible contribution from wind energy. Since 1976 more than 3200 wind turbine units have been installed in Denmark, representing a capacity of roughly 340 MW out of a grid capacity of 8,000 MW. These units are all grid-connected and the unit sizes range from 55 kW to 450 kW. The installed wind energy capacity represents a substantial development of technologies for wind energy utilization during the last 15 years, involving participation from many sides: research institutes, electric utilities, the national energy administration, and private industry. The development has implied a considerable improvement of the technical and economic performance of wind turbines along with increased reliability and durability. The successful development has been strongly supported by comprehensive government programmes, i.e. establishment of a national wind energy research programme, establishment of the Riso Test Station for Windmills and a subsidy scheme for private turbine owners. The improved economic performance is partly the result of a development in rotor size of commercially available wind turbines. In 1981 the largest commercial wind turbine size in Denmark was 55 kW, while today it is close to 500 kW. In the same period the average energy production per installed unit capacity almost doubled, due to enhanced aerodynamic rotor design, increased tower height and improved overall design and production methods.

Wind energy economics

Milborrow, D.J.

1995-01-01

The economics of wind energy have improved rapidly in the past few years, with improvements in machine performance and increases in size both contributing to reduce costs. These trends are examined and future costs assessed. As bank loan periods for wind projects are shorter than for thermal plant, the effect on the price of wind energy is discussed. It is argued that wind energy has a higher value than that of centralised plant, since it is fed into the low voltage distribution network and it follows that the price of wind energy is converging with its value. The paper also includes a brief review of the capacity credit of wind plant and an assessment of the cost penalties which are incurred due to the need to hold extra plant on part load. These penalties are shown to be small. (author)

Denmark has an established wind energy industry. For more than 10 years they have had companies which manufacture production wind turbines for sale on the open market. Over the last five years this industry has matured considerably and there are now at least five companies which sell wind turbines as off the shelf products. Many thousands of Danish wind turbines have been sold around the world and the industry has benefitted greatly from this experience. There are no other European manufacturers who have access to such a large bank of experience. Within Denmark itself, wind energy is considered to be an essentially proven technology. As a result it is an accepted part of the investment market. Approximately 1% of the Danish population (50,000 people) have money invested in wind turbines. Borrowing money for this purpose is almost as well established as the house mortgage system in the UK. (Author)

The wind energy or eolic energy is a consequence of solar energy, the one which is absorbed by the atmosphere and is transformed into energy of movement of large bulks of air. In this process the atmosphere acts as the filter to the solar radiation and demotes the ultraviolet beams that result fatal to life in the Earth. The ionosphere is the most external cap and this is ionized by means of absorption process of ultraviolet radiation arising to the Sun. The atmosphere also acts as a trap to the infrared radiation, it that results from the continual process of energetic degradation. In this way, the interaction between Earth - Atmospheres, is behaved as a great greenhouse, maintaining the constant temperatures, including in the dark nights. Processes as the natural convection (that occur by the thermodynamic phenomenon), equatorial calmness, trade winds and against trade winds and global distribution of the air currents are described. The other hand, techniques as the transformation of the wind into energy and its parameters also are shown

Offshore Wind Energy Permitting: A Survey of U.S. Project Developers

Energy Technology Data Exchange (ETDEWEB)

Van Cleve, Frances B.; Copping, Andrea E.

2010-11-30

The U.S. Department of Energy (DOE) has adopted a goal to generate 20% of the nation’s electricity from wind power by 2030. Achieving this “20% Wind Scenario” in 2030 requires acceleration of the current rate of wind project development. Offshore wind resources contribute substantially to the nation’s wind resource, yet to date no offshore wind turbines have been installed in the U.S. Progress developing offshore wind projects has been slowed by technological challenges, uncertainties about impacts to the marine environment, siting and permitting challenges, and viewshed concerns. To address challenges associated with siting and permitting, Pacific Northwest National Laboratory (PNNL) surveyed offshore wind project developers about siting and project development processes, their experience with the environmental permitting process, and the role of coastal and marine spatial planning (CMSP) in development of the offshore wind industry. Based on the responses to survey questions, we identify several priority recommendations to support offshore wind development. Recommendations also include considerations for developing supporting industries in the U.S. and how to use Coastal and Marine Spatial Planning (CMSP) to appropriately consider ocean energy among existing ocean uses. In this report, we summarize findings, discuss the implications, and suggest actions to improve the permitting and siting process.

Offshore wind energy : balancing risk and reward

International Nuclear Information System (INIS)

Nerland, C.

2010-01-01

Offshore wind energy developments are expected to increase as the demand for renewable energy sources grows. This poster presentation described a method of balancing risk and reward in offshore wind energy projects. The method was based on risk assessment strategies used by the oil and gas industry. The dedicated framework considered schedules; budgets; performance; and operating and maintenance costs. A value chain assessment method was used to optimize the balance between risk and reward by evaluating uncertainties and risk related to each project element and its relationship to other elements within an integrated dynamic model designed to determine the net present value of a project. The decision-making criteria included the RISKEX risk expenditure strategy designed to consider the balance between risk exposure, capital expenditures, and operational expenditures in relation to the statistical cost of unplanned repairs, and lost production capacity. A case study of a large offshore wind farm was used to demonstrate the method. tabs., figs.

This project addresses both fundamental and applied research problems that will help with problems defined by the DOE “20% Wind by 2030 Report”. In particular, this work focuses on increasing the capacity of small or community wind generation capabilities that would be operated in a distributed generation approach. A consortium (KWEC – Kansas Wind Energy Consortium) of researchers from Kansas State University and Wichita State University aims to dramatically increase the penetration of wind energy via distributed wind power generation. We believe distributed generation through wind power will play a critical role in the ability to reach and extend the renewable energy production targets set by the Department of Energy. KWEC aims to find technical and economic solutions to enable widespread implementation of distributed renewable energy resources that would apply to wind.

The Comunidad Autonoma de Madrid (Autonomous Community of Madrid, in the following Madrid Region), is a region located at the geographical centre of the Iberian Peninsula. Its area is 8.028 km{sup 2}, and its population about five million people. The Department of Economy and Technological Innovation of the Madrid Region, together with some organizations dealing on energy saving and other research institutions have elaborated an Energy Plan for the 2004-12 period. As a part of this work, the Fluid Mechanics Laboratory of the Superior Technical School of Industrial Engineers of the Polytechnic University of Madrid has carried out the assessment of the wind energy resources [Crespo A, Migoya E, Gomez Elvira R. La energia eolica en Madrid. Potencialidad y prospectiva. Plan energetico de la Comunidad de Madrid, 2004-2012. Madrid: Comunidad Autonoma de Madrid; 2004]; using for this task the WAsP program (Wind Atlas Analysis and Application Program), and the own codes, UPMORO (code to study orography effects) and UPMPARK (code to study wake effects in wind parks). Different kinds of data have been collected about climate, topography, roughness of the land, environmentally protected areas, town and village distribution, population density, main facilities and electric power supply. The Spanish National Meteorological Institute has nine wind measurement stations in the region, but only four of them have good and reliable temporary wind data, with time measurement periods that are long enough to provide representative correlations among stations. The Observed Wind Climates of the valid meteorological stations have been made. The Wind Atlas and the resource grid have been calculated, especially in the high wind resource areas, selecting appropriate measurements stations and using criteria based on proximity, similarity and ruggedness index. Some areas cannot be used as a wind energy resource mainly because they have environmental regulation or, in some cases, are very close

International wind energy development. World market update 1998. Forecast 1999-2003

International Nuclear Information System (INIS)

1999-03-01

This is the fourth issue of the annual World Market Update from BTM Consult ApS, covering the year 1998. All figures in the status part refer to end of the year 1998, the past 3 years development is also assessed and the forecast looks 5 years ahead. The most significant figures and trends in 1998 were: The marketplace - The annual installation of new wind power capacity increased by 55% resulting in a cumulative installation by the end of 1998 of 10.153 MW. 1.766 MW was installed in Europe and the region is still the leading market regarding utilization of wind energy. The US market took a rapid pace and installed 577 MW during the year. The large Enron Wind Corp has taken the larger part of this market. On the supply side Danish NEG Micon A/S has consolidated the position as being the supplier of the most MW wind capacity in the world and the company has a world market share of 23,5 per cent. The company acquired the Danish Wind World af 1997 A/S which was among the larger companies in 1997. Also the Dutch manufacturer NedWind B.V. was acquired by NEG Micon A/S curing 1998. The group of 'other' manufactureres represents a minor percentage of deliveries than earlier and concentration in the industry seems to continue. The liberalized Energy Market and how to position the industry in this different economic environment will be a challenge for the wind industry way into the next century. In Europe, the European Commission's draft Directive with proposal for an outline of common rules for support of among other renewables wind energy has been set on another route which seems to delay the paper. In the US there are still hopes for a new period with PTC (Production Tax Credit). There are in some States hopes among the wind energy people that the 'Green Market Programs' will play a more dominant role in the future. In Asia the crises seems to halt the wind power development.

2012-12-01

Wind energy is amongst the fastest growing sources of renewable energy in the U.S. and could supply up to 20 % of the U.S power production by 2030. An accurate and reliable wind resource assessment for prospective wind farm sites is a challenging task, yet is crucial for evaluating the long-term profitability and feasibility of a potential development. We have developed an accurate and computationally efficient wind resource assessment technique for prospective wind farm sites, which incorporates innovative statistical techniques and the new NASA Earth science dataset MERRA. This technique produces a wind resource estimate that is more accurate than that obtained by the wind energy industry's standard technique, while providing a reliable quantification of its uncertainty. The focus now is on evaluating the socio-economic value of this new technique upon using the industry's standard technique. Would it yield lower financing costs? Could it result in lower electricity prices? Are there further down-the-line positive consequences, e.g. job creation, time saved, greenhouse gas decrease? Ultimately, we expect our results will inform efforts to refine and disseminate the new technique to support the development of the U.S. renewable energy infrastructure. In order to address the above questions, we are carrying out a cost-benefit analysis based on the net present worth of the technique. We will describe this approach, including the cash-flow process of wind farm financing, how the wind resource assessment factors in, and will present current results for various hypothetical candidate wind farm sites.

Improving weather forecasts for wind energy applications

Science.gov (United States)

Kay, Merlinde; MacGill, Iain

2010-08-01

Weather forecasts play an important role in the energy industry particularly because of the impact of temperature on electrical demand. Power system operation requires that this variable and somewhat unpredictable demand be precisely met at all times and locations from available generation. As wind generation makes up a growing component of electricity supply around the world, it has become increasingly important to be able to provide useful forecasting for this highly variable and uncertain energy resource. Of particular interest are forecasts of weather events that rapidly change wind energy production from one or more wind farms. In this paper we describe work underway to improve the wind forecasts currently available from standard Numerical Weather Prediction (NWP) through a bias correction methodology. Our study has used the Australian Bureau of Meteorology MesoLAPS 5 km limited domain model over the Victoria/Tasmania region, providing forecasts for the Woolnorth wind farm, situated in Tasmania, Australia. The accuracy of these forecasts has been investigated, concentrating on the key wind speed ranges 5 - 15 ms-1 and around 25 ms-1. A bias correction methodology was applied to the NWP hourly forecasts to help account for systematic issues such as the NWP grid point not being at the exact location of the wind farm. An additional correction was applied for timing issues by using meteorological data from the wind farm. Results to date show a reduction in spread of forecast error for hour ahead forecasts by as much as half using this double correction methodology - a combination of both bias correction and timing correction.

Danish and Norwegian wind industry: The relationship between policy instruments, innovation and diffusion

International Nuclear Information System (INIS)

Buen, Jorund

2006-01-01

This article compares the role of policy instruments in stimulating long-term technological change in Danish and Norwegian wind industry. It concludes that although predictability has periodically been low, Denmark's broad portfolio of policies and measures has been well adapted to the different stages in the development of its wind industry. This has contributed to a high degree of innovation, successful establishment in niche markets, high degree of diffusion and establishment of domestic and international mass markets, and-in recent years-an increasingly successful replacement of senescent technology with new. The motivation of Norway's wind energy policies and measures-at least up until the late 1990s-has been to increase power supply rather than to stimulate industrial development and technological change. Policies and measures have been weaker than in Denmark; have been less stable over time; and stimulated the demand side much less. They have not sufficiently covered the wind industry's perceived needs on different stages in the development of new technology, and have not sufficiently stimulated continuous improvement, learning and new product development (dynamic efficiency) in industry. This has been part of the reason why there has been only a limited extent of innovation and diffusion of wind technology in Norway

In the context of the wind power use increase in the european union, the average wind turbines power increases also. These turbines are more adapted to little wind conditions. The offshore wind power is certainly the more adapted to the problem of implementation sites, meanwhile the offshore project costs are more expensive. More competitive costs are a challenge for the offshore wind channel. The author presents also the main technological evolutions, the french wind power industry and the future of this energy in France. (A.L.B.)

Wind energy in Europe

1992-02-01

Interest in wind energy as a supplementary source for the production of electricity has recently gained renewed momentum due to widespread concern about environmental impacts from the large scale use of fossil fuels and nuclear energy. In addition, political unrest in the Middle East has drawn attention to the importance of national energy self-sufficiency. European government administrations, however, have not yet fully appreciated the real worth of the 'clean energy' afforded by wind energy. In this regard, the European Wind Energy Association (EWEA) is acting as a strong voice to inform the public and energy planners by stimulating international wind energy R ampersand D cooperation, and organizing conferences to explain the advantages of wind energy. In October 1991, EWEA published a strategy document giving a picture of the real possibilities offered by wind energy within the geographical, social, and European economic context. This paper provides an overview of the more significant features to emerge from this document which represents a useful guideline for wind power plant technical/economic feasibility studies in that it contains brief notes on resource availability, land requirements, visual and acoustic impacts, turbine sizing, performance, interconnection to utility grids, maintenance and operating costs, safety, as well as, on marketing aspects

Swainson’s hawks (Buteo swainsoni) are a long-distance migratory species that breed in western North America and winter in Argentina. As a grassland species, they can also be found in agricultural settings, such as croplands and pastures. Wind energy is expanding rapidly across the breeding range of the population we chose to study, and we suspect the industry is also expanding in their wintering range and across the migratory pathway. Wind turbines pose a threat to birds, and migratory species may be especially susceptible to turbine-related mortality when these structures are placed in important migratory pathways. The purposes of this longterm study were to examine potential threats that wind energy might pose to Swainson’s hawks on the breeding range, wintering range, and during migration, add to the body of ecological knowledge on migration and wintering habits, and describe breeding habits in a portion of their range that is relatively understudied.

Full Text Available One of the fundamental tasks of modern power system is finding ways to produce stable and continuous electricity from scarce energy resources. One of the possible solutions is introduction, implementation and improvement of alternative forms of energy such as renewable energy sources, particularly wind energy as an increasingly important energy source which is expected to further increase its share in total electricity production. Numerous methods can be used in assessing the efficiency of wind energy companies, and in the focus of this research is the Data Envelopment Analysis method (DEA, a widely accepted methodology given its interdisciplinary approach and flexibility. This method represents a step forward in the field of renewable energy management, because it provides the possibility to compare the selected companies with the best in the industry (the most efficient and the possibility of determining sources of inefficiency and, consequently, the possibilities of their elimination.

Full Text Available The clean energy industry has been growing in Costa Rica, especially wind energy, during the last years. However, at least for the best of our knowledge, published scientific information about diversity, and collision rates, upon bats and birds in wind farms of Costa Rica is not-existent. In this manuscript we highlight the importance of establish biological monitoring programs in the wind farms, to determinate changes in the diversity of flying vertebrates, as well to evaluate the impact of wind towers upon the local and regional biodiversity. We suggest to public and private actors involving in wind energy production and conservation in Costa Rica to work together in order to answer the questions formulated in this manuscript as a priority, and eventually mitigate effectively any potential threat on our biodiversity. The development of research and politics related with those issues is critical to make correct decisions in relation with the wind energy future of the country in armony with nature.

1995-01-01

The National Government of Colombia assigned to INEA (Institute of Nuclear Sciences and Alternative Energies), the paper of promotion, diffusion and utilization of sources of energy not - conventional, the one which includes the wind energy. These studies were accomplished mainly in winding zones as the Department La Guajira, area of the Eastern Plains and some sites of mountain chains of the Andes. Internationally, renewable energies utilization is widely used and is included as an important factor in the energetic strategic planning in some countries, where this renewable energy becomes more than 20% to total energy supply. An introduction to the wind energy in some aspects as: the wind resource, global traffic standards of the wind, calculation of the potential of the wind and methods for the calculation of speed measure of the wind are presented. The methodologies for the evaluation of the wind as an energy source, the wind energy technologies, the equipment to wind energy utilization and the implementation of small systems of energy conversion of wind are described

Mobilising for marine wind energy in the United Kingdom

International Nuclear Information System (INIS)

Jay, Stephen

2011-01-01

Since 2000, the United Kingdom has enthusiastically adopted marine wind energy as a potentially major source of electricity production and has become the leading nation in terms of output. This is in contrast to its relatively poor attainment of wind energy on land, and raises questions about the reasons for this difference in performance. This article traces the phases of development of marine wind energy in the UK with reference to factors that are instrumental in the uptake of this form of renewable energy. A number of features emerge from this analysis that stand in some contrast to the situation on land and help to explain the UK's current status. These include: recognition of an exceptional resource and relative ease of exploitation; government commitment and policy geared to controlled growth and strategic oversight, adequate economic support and start-up investment; the unusual rights and interests of the Crown Estate; and growing scale, confidence and organisation on the part of the industry. Set against these factors are the complexities of consenting, supply bottlenecks, and some stakeholder and public resistance, though these are outmatched by the drivers in favour of development and are being partly addressed. - Highlights: → The United Kingdom is demonstrating enthusiastic commitment to marine wind energy. → The features contributing to marine wind energy growth are analysed. → The UK has unique factors favouring the uptake of marine wind energy. → UK policy is geared to controlled growth and strategic oversight. → The Crown Estate's seabed rights and interests are a driver in implementation.

Suitability analysis of wind energy development on brownfields, landfills and industrial sites in the city of Chicago

Science.gov (United States)

Fyodorova, Valeryia A.

In 2011 renewable energy generated only about 5% of total U.S. electricity and 3% came from wind power. Wind power is the oldest and fastest growing renewable energy, and U.S. Department of Energy (DOE) anticipates that by 2030 the potential of the U.S. to generate wind power will rise up to 20% (National Renewable Energy Laboratory 2008). Currently, the rural areas serve as the primary choice of wind turbine installation because there are less wind obstacles that create wind turbulence, which in turn is disruptive for the proper functioning of the wind turbines, and allows more laminar (streamline) wind flow. However according to various literatures, the installation of wind turbines in rural areas has its drawbacks. The infrastructure is underdeveloped and usually the selected sites require the construction of new roads and transmission lines. The new construction and occasional deforestation lead to soil erosion and environmental degradation. On top of that transporting energy to cities that are the primary consumers of wind energy results in energy transmission loss. Urban areas, on the other hand, have well developed infrastructure, and the installation of turbines on abandoned and contaminated urban lands which are expensive to clean and rehabilitate for other uses would lower installation costs and would have little environmental degradation effect. The objective of this research was to provide a preliminary wind power suitability analysis for installing medium (100 -1000 kW) and large (1000 - 3000 kW) size wind turbines in urban areas, such as city of Chicago. Geographic Information Systems (GIS) and a multi attribute Weighted Linear Combination (WLC) method that is based on the concept of weighted average were primary tools utilized to conduct the analysis. The criteria that were used to select suitable sites were the same criteria used for rural wind farms, such as wind speeds, historic landmarks, avian and wildlife habitat, conservation lands, proximity

Highlights: • Integrated assessment model perform a series of scenarios of technology advances. • Explore the potential roles of wind energy technology advance in global energy. • Technology advance impacts on energy consumption and global low carbon market. • Technology advance influences on global energy security and stability. - Abstract: To avoid additional global warming and environmental damage, energy systems need to rely on the use of low carbon technologies like wind energy. However, supply uncertainties, production costs, and energy security are the main factors considered by the global economies when reshaping their energy systems. Here, we explore the potential roles of wind energy technology advancement in future global electricity generations, costs, and energy security. We use an integrated assessment model performing a series of technology advancement scenarios. The results show that double of the capital cost reduction causes 40% of generation increase and 10% of cost ​decrease on average in the long-term global wind electricity market. Today’s technology advancement could bring us the benefit of increasing electricity production in the future 40–50 years, and decreasing electricity cost in the future 90–100 years. The technology advancement of wind energy can help to keep global energy security and stability. An aggressive development and deployment of wind energy could in the long-term avoid 1/3 of gas and 1/28 of coal burned, and keep 1/2 biomass and 1/20 nuclear fuel saved from the global electricity system. The key is that wind resources are free and carbon-free. The results of this study are useful in broad coverage ranges from innovative technologies and systems of renewable energy to the economic industrial and domestic use of energy with no or minor impact on the environment.

Weather-power station. Solar energy, wind energy, water energy

Energy Technology Data Exchange (ETDEWEB)

Schatta, M

1975-10-02

A combined power station is described, which enables one to convert solar energy and wind energy into other forms of energy. The plant consists of a water-filled boiler, in which solar energy heats the water by concentration, solar cells, and finally wind rotors, which transform wind energy into electrical energy. The transformed energy is partly available as steam heat, partly as mechanical or electrical energy. The plant can be used for supplying heating systems or electrolysis equipment. Finally, by incorporating suitable motors, a mobile version of the system can be produced.

A Wind Forecasting System for Energy Application

Science.gov (United States)

Courtney, Jennifer; Lynch, Peter; Sweeney, Conor

2010-05-01

Accurate forecasting of available energy is crucial for the efficient management and use of wind power in the national power grid. With energy output critically dependent upon wind strength there is a need to reduce the errors associated wind forecasting. The objective of this research is to get the best possible wind forecasts for the wind energy industry. To achieve this goal, three methods are being applied. First, a mesoscale numerical weather prediction (NWP) model called WRF (Weather Research and Forecasting) is being used to predict wind values over Ireland. Currently, a gird resolution of 10km is used and higher model resolutions are being evaluated to establish whether they are economically viable given the forecast skill improvement they produce. Second, the WRF model is being used in conjunction with ECMWF (European Centre for Medium-Range Weather Forecasts) ensemble forecasts to produce a probabilistic weather forecasting product. Due to the chaotic nature of the atmosphere, a single, deterministic weather forecast can only have limited skill. The ECMWF ensemble methods produce an ensemble of 51 global forecasts, twice a day, by perturbing initial conditions of a 'control' forecast which is the best estimate of the initial state of the atmosphere. This method provides an indication of the reliability of the forecast and a quantitative basis for probabilistic forecasting. The limitation of ensemble forecasting lies in the fact that the perturbed model runs behave differently under different weather patterns and each model run is equally likely to be closest to the observed weather situation. Models have biases, and involve assumptions about physical processes and forcing factors such as underlying topography. Third, Bayesian Model Averaging (BMA) is being applied to the output from the ensemble forecasts in order to statistically post-process the results and achieve a better wind forecasting system. BMA is a promising technique that will offer calibrated

Economics of wind energy

International Nuclear Information System (INIS)

Ranganathan, V.; Kumar, H.P.S.

1991-01-01

Conventional economic analysis of wind energy often ignores the fact that it is not an energy source available on tap, but is intermittent. The analysis at times is discriminatory in the sense that the costs of transmission and distribution are added to the central grid alternative but the costs of the locational constraints of wind energy siting are not quantified. This paper evaluates wind energy after correcting for these two factors. The results are not encouraging

Wind power - research and development. The wind turbine industry's view of the promotion of state-supported research and development

International Nuclear Information System (INIS)

Kroh, S.

1995-10-01

The windmill industry in Denmark is currently confronted with making a choice between competing technologies so that the role of the stimulus of state subsidies for research has lately increased in importance. The Ministry of Energy, it is claimed, must be aware of this as possibilities for making use of research results are dictated by the market and competition. The industry is not sympathetic to the idea of state research contracts with specified goals for which manufacturers must produce a technical solution. Consultancy firms should work towards solving general problems which could help the industry as a whole. Wind turbines which are cheap to produce and operate are of more interest to industry than those which are technologically advanced or of a lighter construction. It is not thought to be advantageous to concentrate the allocation of subsidies on one key project chosen by the Ministry itself, such as the current intense interest in turbine blades. Aerodynamics, noise pollution and materials are considered as more vital areas for research. A special interest in smaller windmills is not currently relevant. Evaluations of the quality of research projects demanding subsidies should be more critical. A detailed list of subjects within this field which are considered as being relevant for research is given. The Danish windmill industry advises a centralized wind power research institution and a gradual shift of the test station at Risoe National Laboratory to Jutland as wind conditions at Risoe are not considered satisfactory. A better communication between Risoe test station and the wind power industry is recommended. (AB)

CNE has conducted a feasibility study on the Chilocco property in north-central Oklahoma since the grant award on July 20, 2003. This study has concluded that there is sufficient wind for a wind farm and that with the Production Tax Credits and Green Tags, there will be sufficient energy to, not only cover the costs of the Nation’s energy needs, but to provide a profit. CNE has developed a wind energy team and is working independently and with industry partners to bring its renewable energy resources to the marketplace. We are continuing with the next phase in conducting avian, cultural and transmission studies, as well as continuing to measure the wind with the SoDAR unit. Cherokee Nation Enterprises, Inc. is a wholly-owned corporation under Cherokee Nation and has managed the Department of Energy grant award since July 20, 2003. In summary, we have determined there is sufficient wind for a wind farm at the Chilocco property where Cherokee Nation owns approximately 4,275 acres. The primary goal would be more of a savings in light of the electricity used by Cherokee Nation and its entities which totals an estimated eight million dollars per year. Cherokee Nation Enterprises (CNE), working independently and with industry partners, plans to bring its renewable energy resources into the marketplace through a well-documented understanding of our undeveloped resource. Our plan is to cultivate this resource in a way that will ensure the development and use for our energy will be in an environmentally and culturally acceptable form.

Assessing climate change impacts on the near-term stability of the wind energy resource over the United States.

The energy sector comprises approximately two-thirds of global total greenhouse gas emissions. For this and other reasons, renewable energy resources including wind power are being increasingly harnessed to provide electricity generation potential with negligible emissions of carbon dioxide. The wind energy resource is naturally a function of the climate system because the "fuel" is the incident wind speed and thus is determined by the atmospheric circulation. Some recent articles have reported historical declines in measured near-surface wind speeds, leading some to question the continued viability of the wind energy industry. Here we briefly articulate the challenges inherent in accurately quantifying and attributing historical tendencies and making robust projections of likely future wind resources. We then analyze simulations from the current generation of regional climate models and show, at least for the next 50 years, the wind resource in the regions of greatest wind energy penetration will not move beyond the historical envelope of variability. Thus this work suggests that the wind energy industry can, and will, continue to make a contribution to electricity provision in these regions for at least the next several decades.

Impact of public policy uncertainty on renewable energy investment: Wind power and the production tax credit

International Nuclear Information System (INIS)

Barradale, Merrill Jones

2010-01-01

It is generally understood that the pattern of repeated expiration and short-term renewal of the federal production tax credit (PTC) causes a boom-bust cycle in wind power plant investment in the US. This on-off pattern is detrimental to the wind industry, since ramp-up and ramp-down costs are high, and players are deterred from making long-term investments. It is often assumed that the severe downturn in investment during 'off' years implies that wind power is unviable without the PTC. This assumption turns out to be unsubstantiated: this paper demonstrates that it is not the absence of the PTC that causes the investment downturn during 'off' years, but rather the uncertainty over its return. Specifically, it is the dynamic of power purchase agreement (PPA) negotiations in the face of PTC renewal uncertainty that drives investment volatility. With contract negotiations prevalent in the renewable energy industry, this finding suggests that reducing uncertainty is a crucial component of effective renewable energy policy. The PTC as currently structured is not the only means, existing or potential, for encouraging wind power investment. Using data from a survey of energy professionals, various policy instruments are compared in terms of their perceived stability for supporting long-term investment. - Research highlights: →The case of wind energy investment in the face of PTC uncertainty provides an important study in how industry structure, and in particular the process of contract negotiations, can amplify the impact of public policy uncertainty on corporate investment. →The finding that contract negotiations in the face of uncertainty are sufficient in themselves to hinder investment implies that the assumption that investment downturns reflect unfavorable economics is unfounded. This assumption falsely discourages interest and investment in wind energy. →Policy stability should be added to the list of criteria explicitly considered in designing policy

Does wind energy mitigate market power in deregulated electricity markets?

International Nuclear Information System (INIS)

Ben-Moshe, Ori; Rubin, Ofir D.

2015-01-01

A rich body of literature suggests that there is an inverse relationship between wind power penetration rate into the electricity market and electricity prices, but it is unclear whether these observations can be generalized. Therefore, in this paper we seek to analytically characterize market conditions that give rise to this inverse relationship. For this purpose, we expand a recently developed theoretical framework to facilitate flexibility in modeling the structure of the electric industry with respect to the degree of market concentration and diversification in the ownership of wind power capacity. The analytical results and their attendant numerical illustrations indicate that the introduction of wind energy into the market does not always depress electricity prices. Such a drop in electricity prices is likely to occur when the number of firms is large enough or the ownership of wind energy is sufficiently diversified, or most often a combination of the two. Importantly, our study defines the circumstances in which the question of which type of firm invests in wind power capacity is crucial for market prices. - Highlights: • Studies show that electricity prices decrease with increased wind power capacity. • We investigate market conditions that give rise to this inverse relationship. • Average prices for wind energy are systematically lower than average market prices. • Conventional generation firms may increase market power by investing in wind farms. • Energy policy should seek to diversify the ownership of wind power capacity

Planners to the rescue: spatial planning facilitating the development of offshore wind energy.

Science.gov (United States)

Jay, Stephen

2010-04-01

The development of offshore wind energy has started to take place surprisingly quickly, especially in North European waters. This has taken the wind energy industry out of the territory of planning systems that usually govern the siting of wind farms on land, and into the world of departmental, sectoral regulation of marine activities. Although this has favoured the expansion of offshore wind energy in some respects, evidence suggests that the practice and principles of spatial planning can make an important contribution to the proper consideration of proposals for offshore wind arrays. This is especially so when a strategic planning process is put in place for marine areas, in which offshore wind is treated as part of the overall configuration of marine interests, so that adjustments can be made in the interests of wind energy. The current process of marine planning in the Netherlands is described as an illustration of this. (c) 2009 Elsevier Ltd. All rights reserved.

2010-09-15

'Green Energy' is the call of the day, and significance of Wind Energy can never be overemphasized. But the key question here is - What if the wind resources are inadequate? Studies reveal that the probability of finding favorable wind at a given place on land is only 15%. Moreover, there are inherent uncertainties associated with wind business. Can we overcome inadequate wind resources? Can we scientifically quantify uncertainty and model it to make business sense? This paper proposes a solution, by way of break-through Wind Technologies, combined with advanced tools for Financial Modeling, enabling vital business decisions.

Critical materials: wind industry and solar industry are battling

2015-01-01

Neodymium, dysprosium, tellurium, indium and gallium are materials whose shortage and price fluctuations could have an impact on the development of wind energy and solar energy as about a quarter of the production of rare earth elements is used for the fabrication of permanent magnets. Between 1966 and 1984 the United States were the first producer in the world, then the production of these materials has moved little by little towards China. In 2010 China produced 97% of rare earth elements and in the same year it reduced the quantities to export which led to a panic in the market. Now governments and the industry are facing the challenge. New production capacities have been opened particularly in the United-States and Australia, ancient mines have been re-opened, recycling policies have been developed and an optimization of the use of rare-earth elements has been favored.

A wind energy system converts the kinetic energy of the wind into mechanical or electrical energy that can be harnessed for practical uses and transform the economy of rural areas where access to water and electricity is very restricted and industry is almost nonexistent in most of the developing countries like Rwanda. Assessing wind power potential for a location is an imperative requirement before making a decision for the installation of windmills or a wind electric generator and evaluating plans for relating projects. The aim of the present study was to evaluate the potential of wind resource in Rwanda and to constitute a database for the users of the wind power. A time series of hourly daily measured wind speed and wind direction for the period between 1974 and 1993 on five main Rwandan meteorological stations was provided by the National Meteorology Department. Statistical methods applying Weibull and Rayleigh distribution were presented to evaluate the wind speed characteristics and the wind power potential at a height of 10 m above ground level using hourly monthly average data. Those characteristics were extrapolated for higher levels in altitude. The results give a global picture of the distribution of the wind potential in different locations of Rwanda. (author)

results are often text-based demonstrations. WINS includes a powerful visualization tool and user interface capability for transmission analyses, planning, and assessment, which will be of great interest to power market participants, power system planners and operators, and state and federal regulatory entities; and (3) WINS can handle extended transmission models for wind integration studies. WINS models include limitations on transmission flow as well as bus voltage for analyzing power system states. The existing decision tools often consider transmission flow constraints (dc power flow) alone which could result in the over-utilization of existing resources when analyzing wind integration. WINS can be used to assist power market participants including transmission companies, independent system operators, power system operators in vertically integrated utilities, wind energy developers, and regulatory agencies to analyze economics, security, and reliability of various options for wind integration including transmission upgrades and the planning of new transmission facilities. WINS can also be used by industry for the offline training of reliability and operation personnel when analyzing wind integration uncertainties, identifying critical spots in power system operation, analyzing power system vulnerabilities, and providing credible decisions for examining operation and planning options for wind integration.

Spain is apparently contradictory. It figures among the European countries farthest from the Kyoto Protocol's objectives but is often cited as an example, even by President Obama, for its success in speeding up developments in renewable energy. Successes in solar and wind power have proven that Spanish industry can, with support from the state and within a decade, develop to become competitive internationally at the very time when climate change will be having repercussions on economic models and opening new markets. From this vantage point, big projects (like the Mediterranean Solar Plan or future European Union initiatives related to the Energy-Climate package) should stimulate the Spanish, who will probably soon be looking for European partners. Given its advantages in wind and solar energy, the country should be able to consolidate an efficient energy solution with a promising future, while reinforcing its particularly innovative industry.

Assessing Potential Wind Energy Resources in Saudi Arabia with a Skew-t Distribution

KAUST Repository

Tagle, Felipe

2017-03-13

Facing increasing domestic energy consumption from population growth and industrialization, Saudi Arabia is aiming to reduce its reliance on fossil fuels and to broaden its energy mix by expanding investment in renewable energy sources, including wind energy. A preliminary task in the development of wind energy infrastructure is the assessment of wind energy potential, a key aspect of which is the characterization of its spatio-temporal behavior. In this study we examine the impact of internal climate variability on seasonal wind power density fluctuations using 30 simulations from the Large Ensemble Project (LENS) developed at the National Center for Atmospheric Research. Furthermore, a spatio-temporal model for daily wind speed is proposed with neighbor-based cross-temporal dependence, and a multivariate skew-t distribution to capture the spatial patterns of higher order moments. The model can be used to generate synthetic time series over the entire spatial domain that adequately reproduces the internal variability of the LENS dataset.

Brazil's primary energy matrix is based on more than 47% of renewables, and more than 85% of its electricity is generated by hydro power sources. Despite this large fraction of renewable energy resources, less than 0.3% of the national energy supply comes from solar or wind sources. This paper presents a diagnostic review on the penetration of the solar and wind energy technologies in Brazil. It also includes a survey of the latest government policies and incentives for renewable energies deployment by entrepreneurs, industry and commercial and residential consumers. In addition, the paper analyses how to best meet the requirements for policy support and information technology to boost the deployment of solar technology and wind energy in Brazil. This study was mostly based on results of a widely distributed survey covering key issues, and also by personal interviews carried out with key stakeholders in order to better understand the issues highlighted in the survey responses.
