  • 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 ...

  • Powering Renewable Programs: The Utility Perspective

    When considering how to build out a renewable energy portfolio, there are a lot of factors and many points of view to consider. For purposes of this narrative, we will take the point of view of the electric utility itself. Your electricity providers are quite familiar with the concept of a “smart grid.” According to the Department of Energy (DOE), a smart grid “generally refers ...

  • Energetic and exergetic assessment of solar and wind potentials in Europe

    This paper deals with a physics–based assessment of renewable energy potential in Europe, particularly solar and wind energy sources, using two literature models. A sensibility analysis with the weather data is first done. Actual temperature, pressure, relative humidity, global radiation and wind speed data are employed to develop energy and exergy maps for Europe, based on iso–areas of land–use. ...

  • Energy and exergy assessments for potential wind power in Turkey

    The main objective of the study is to estimate wind power potential of Turkey and provide suitable data for evaluating potential wind power by using the wind data collected at 23 different wind-monitoring stations. In this study, energy and exergy analyses of wind power are used to estimate wind power potential in these areas. Exergy analysis of wind power is investigated according to air ...

  • Comparative life cycle assessment of 2.0 MW wind turbines

    Wind turbines produce energy with virtually no emissions, however, there are environmental impacts associated with their manufacture, installation, and end of life. The work presented examines life cycle environmental impacts of two 2.0 MW wind turbines. Manufacturing, transport, installation, maintenance, and end of life have been considered for both models and are compared using the ReCiPe 2008 ...

  • Multi-megawatt wind turbines for offshore use: aspects of Life Cycle Assessment

    Life Cycle Assessment (LCA) is an instrument to quantify environmental impacts of the entire energy supply chain. According to the LCA, an appropriate indicator system should comprise all steps of a system's life cycle: production, operational and disposal processes ("cradle-to-grave"). Cumulative Energy Demand (CED) might be seen as one part of LCA as far as the depletion of energy resources in ...

  • On wind energy, electricity free market, and life cycle assessment in Brazil

    This paper assesses strategies to foster market development for the wind energy in Brazil, based on the importance of the consumption of this renewable energy to minimise environmental and social impacts of the productive life cycles, assuming the existence of economic and legal incentives. The analysis encompasses five descriptive phases. The first one describes the Brazilian wind energy ...

  • An integrated assessment for wind energy in Lake Michigan coastal counties

    The benefits and challenges of onshore and offshore wind energy development were assessed for a four‐county area of coastal Michigan. Economic, social, environmental, and spatial dimensions were considered. The coastal counties have suitable wind resources for energy development which could contribute toward Michigan's ten percent renewable energy standard. Wind energy is cost‐effective with ...

  • Carnedd Wen Wind Farm

    In 2005 npower renewables began investigating the possibility of building one of the largest wind farms in Wales. The farm would consist of 65 turbines standing up to 137 metres high on around 2,600 hectares (ha) of hillside near Llanbrynmair in Powys. To help enhance the impact of the wind farm, npower renewables propose an extensive habitat restoration scheme following clearance of over ...

  • Prospects of wind energy in India

    This paper is a modest attempt to study the growth and performance of wind farms in India. India occupies the 5th place in the world in wind energy generation after Germany, the USA, Denmark and Spain, and has an installed capacity of more than 2485 MW of wind energy, comprising both commercial projects (2418 MW) and demonstration projects (65.415 MW) as of 31 March 2004. This paper discusses the ...

  • 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 ...

  • The Future Cost of Wind Power

    Chapter 1 The economics of wind power Wind power is capital intensive with most of the investment required upfront. The largest capital cost component is the turbine itself which can account for between 40% and 80% of the total capital cost of an onshore wind installation. Costs offshore are higher because of the more expensive operating environment and the greater difficulty establishing ...

  • 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 ...


  • New methods for measuring the wind

    Although computer models of wind flow over terrain have improved dramatically in the past few years, there is still no substitute for data recorded at the site. So you want to build a wind farm. Good for you. With the global drive towards a low carbon economy, it is surely the right way to go for many individuals, companies and, indeed, Governments around the world. As information from the ...


  • 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 ...

  • Life cycle assessment of a 150 MW offshore wind turbine farm at Nysted/Roedsand, Denmark

    The purpose of this life cycle assessment (LCA) was to illuminate and describe the potential environmental impacts caused by an offshore wind turbine farm (WTF) throughout its lifetime and use this knowledge in the planning and improvement of future WTFs. The LCA was based on experience from the LCA on Danish electricity and district heating [1] as well as the offshore WTF project at ...

  • A review of wind energy developments in India

    Climate change, dwindling reserves of fossil fuels and shortage of electricity have prompted the government to give an impetus to renewable energy sources. Wind energy, with an average growth rate of 30%, is the fastest growing source of renewable energy in the world. India has a potential capacity of over 45,000 MW out of which 1869 MW has been extracted from this eco-friendly source. India ...
