  • Wind Energy Production Estimates: Moving Beyond Time Averages

    No need to be a statistician to see that averages are often useful to compare different things. And yet, they often fall short as a true measure of performance. For instance, we use averages to compare the current weather against the climate normals or to get a sense of how our favorite sport team or player is doing. Team (player) statistics are a concise way of combining the scores from many ...

  • ´More Stations. More Data. Better Forecasts.´ – the NYS Mesonet

    “More Stations. More Data. Better Forecasts.” – that’s the slogan of New York State Mesonet. The weather observation network consists of a total of 125 weather stations all over the state of New York and Lufft was selected as one of the vendors to support them in capturing the data. All 125 of the weathers stations have the standard instrumentation suite. Of those 125, 17 ...

  • Renewable energy production issues with the Cape Cod offshore wind energy programme

    This paper evaluates the first offshore wind farm proposal in the USA. It is being put forward by Cape Wind Associates, a Boston-based firm that wishes to build 170 turbines five miles offshore in Nantucket Sound. The proposed development would supply up to 95% Cape Cod's energy needs and 2% of the energy requirements for the eastern New England region, preventing the need for additional fossil ...

  • Wind energy today and in the 21st century

    Wind energy is the most promising of the new renewable sources of energy. By the end of 1998, the global installed capacity of modern grid connected wind turbines was some 10,000 MW, and the growth rates of installations worldwide are 30%-40% annually. The cost of wind energy was reduced by 30% between 1991 and 1997 and the cost reduction is foreseen to continue. This article reviews the reasons ...

  • Wind Energy Market in China 2014

    This latest market research report titled Wind Energy Market in China 2014 analyses how the renewable energy sector is gaining importance in China and how wind energy has become an indispensable part of this sector. With the gap in demand and supply of energy increasing at a steady pace, it has become necessary to look beyond conventional sources for generating energy. This has led to a shift in ...

  • Wind & solar energy and nature conservation

    Climate change and the degradation of ecosystems and biodiversity cannot be solved in isolation. Land and marine ecosystems play a crucial role in the climate system, capturing roughly half of carbon dioxide emissions generated by human activities (UNEP, 2009). Protecting biodiversity preserves ecosystem services that are important for regulating the climate and helping us to adapt to the impacts ...

  • Analysis of vertical wind shear in the Southern Great Plains and potential impacts on estimation of wind energy production

    This paper describes the analysis of near-surface wind speeds in Western Oklahoma. The goals of this research are to characterise the nocturnal low-level jet (LLJ) in the region, and to assess the impact wind variability, vertical shear and the LLJ on wind energy calculations. Results show the seasonal variability in wind characteristics as well as in the vertical wind shear, and also illustrate ...

  • Wind energy in Italy: regulatory and technical aspects

    Italy has carried out the deregulation of the electricity sector. The EU 'Renewable Directive' gave Italy a very ambitious burden sharing: by 2010, 25% of the demand will be faced by renewable energy against a 1997 baseline of 16%. To sustain such development, the producers/importers have a yearly obligation to inject into the system 'green production': in 2002 by 2% increasing to 3.05% by 2006 ...

  • Verification of wind energy related measurements with a SODAR system

    Abstract Complex terrain and growing wind energy converters (WEC) in wind parks generate increasing interest in determining wind profiles and turbulence besides the general forecast of annual energy production. Increasing hub heights and growing rotor diameters of advanced WEC make SODAR systems a valuable alternative to meteorological towers. SODAR systems provide wind profiles as well as ...

  • Ocean Thermal Energy and Water Production

    Introduction The scarcity of potable water is a growing problem worldwide, particularly in arid regions and among developing countries. Compounding this problem is the increasing contamination of freshwater sources, which comprise only about 2.5% of all water on Earth. Of this small portion, only 0.5% of the total fresh water available is found in easily accessible sources such as ...

  • Advanced offshore measurements to support wind energy production, weather forecasting, and emergency response

    Sonoma Technology, Inc. (STI), with support from the Bureau of Ocean Energy Management, is leading a unique partnership of corporate, government, and university researchers to develop a marine environmental observations program in the Gulf of Mexico. The primary goal of this project is to develop a framework of advanced offshore measurements to support emergency response, oil and gas exploration ...

  • Productivity of small wind turbines for various wind potentials conditions: application in Bulgaria and Corsica

    Less or more accurate power curve models are generally used to simulate the wind turbine electrical production versus the available wind speed. However, if such models are adapted to large machines, this is not the case for small ones. The objective of this paper is to study the impact of different small-scale wind turbines power curves and wind distributions on the electrical production. An ...

  • Wind farms benefting the region

    Wind farms as close as Benton and White counties—and others around the world—are boosting Tippecanoe County’s economy by at least $20 million a year, reports Jody Hamilton, director of economic development for Greater Lafayette Commerce. “From land title searches to construction labor and turbine components, businesses in Greater Lafayette are enjoying new revenues, and that figure doesn’t ...

  • Wind power growth in the US

    Last year was a banner year for renewable energy in the United States, especially for the wind industry. As the recent REN21 Renewables 2007 Global Status Report highlights, the industry broke all past global records, installing 5,244 megawatts (MW) of new wind energy capacity in 2007, or 30 percent of all new U.S. capacity added. This brings the cumulative national total close to 17,000 ...

  • Wind Generators as Role Models

    Advanced speed control methods are available for the regulation of wind generators. Working together with SET Sustainable Energy Technologies GmbH, Sulzer made use of one of these new concepts on pumps for the first time and implemented it with great success on a feedwater pump in a refinery. Unregulated pumps consume unnecessary drive energy when demand fluctuates. By controlling ...

  • Measuring Offshore Wind Resources

    To select the right offshore wind site, estimate the future energy output of a wind farm, and determine the best layout for the turbines, project developers must conduct wind resource assessment (WRA) campaigns on site. This is a critical phase of the successful development of wind farms. WRA campaigns on terrestrial sites have traditionally been performed using meteorological towers equipped ...

  • Wind turbine controlling of the future

    Higher, more robust, more reliable: Parallel to the growing requirements for wind turbines, the requirements for monitoring sensors grow as well. But how can wind sensor manufacturers fulfil these wishes? And how should a future wind sensors look like? After analysing the current conditions and trends on the wind energy market, our CEO Klaus Hirzel compiled a wish list for future wind sensors. ...

  • Drones for Wind Turbine Inspection

    Unmanned Aerial Vehicles and Inspection Services for Wind Turbines: Global Market Assessment and Forecasts By the beginning of 2015, there were nearly 270,000 individual wind turbines operating globally. The more than 800,000 blades spinning on these turbines are battered by the elements over time and gradually wear out. Deterioration can cause reduced energy ...

  • Amassing Wind Information

    Wind is a variable resource, but not an indecipherable one. Second Wind encourages harnessing the full range of wind sensing technologies that are available today. When it comes to wind information, much attention is focused on the choice of wind measurement technology and data collection practices in wind resource assessment and project design. Right now, wind data plays a limited role in the ...
