  • 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 ...

  • Reducing avian collisions with wind turbines

    Wind is an important renewable energy source for Europe. The wind power capacity installed in 2014 could produce enough electricity to meet over 10% of the EU’s electricity consumption. However, wind power structures can also be harmful to birds, which can collide with turbines. This study assessed methods of reducing avian collisions with wind turbines and makes several practical ...

  • 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 ...

  • 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 ...

  • 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 ...


  • Wind modelling based on wind input data conditions using Weibull distribution

    Weibull distribution can be used to model the wind speed distribution at a particular site and hence, it can help in wind resource assessment (WRA) of a site. By calculating the shape (k) and scale (c) parameters for Weibull distribution, the wind speed frequency curve for a site can be made. Once this wind speed distribution for site is determined, it can be convolved with the power curve for a ...

  • Offshore wind costs and development risk

    How procurement strategies, manufacturing costs and new technology stack up against development risk in Offshore Wind Projects. Offshore wind is changing, and it is changing for the better. In 2006, offshore wind deployment costs started rising significantly, from £1.5m/ MW, in 2016 prices, to over £4m/MW in 2012, without a clear indication as to what the price ceiling would ...

  • 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 ...

  • Technological innovations driving down lifetime costs of producing wind power

    This report analyzes the opportunities and challenges facing wind power in North America – particularly turbine manufacturers – in the current economic and political climate. It assesses drivers of growth include rising demand for electricity, pro-wind regulatory environments, advantages over other renewables, and technological innovations driving down lifetime costs of producing wind power. Key ...


  • Renewable, clean energy: the petroleum footprint - wind farms under analysis

    This paper presents a methodology to assess projects for the generation of clean, renewable energy. Such methodology is applied here to estimate the consumption of fossil fuels (referred to as 'oil'), required for the construction, operation and maintenance of a wind farm consisting of 97 turbines of 3 MW each. Results show that such consumption represents a conservative 8–9% of the total energy ...

  • How sustainable are our energy technologies? Photovoltaics and wind energy systems as examples

    The energy sector plays a key role within the concept of Sustainable Development. Therefore, sustainability aspects should be considered when new energy systems are assessed. How does a specific supply option contribute to a desired sustainable development of the energy system? To answer this question, indicators are needed. These should cover the most significant sustainability issues of the ...

  • 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 ...

  • Offshore Wind Versus Solar in the Eastern US: An Unexpected Rivalry

    Less than a decade ago, offshore wind energy and solar PV were similarly priced energy sources. Unsubsidized installed costs for both exceeded $5 per watt, or more than double that for land-based wind. Despite their cost, both technologies were seen as the best hopes for supplying urban centers with green power, especially in the BOSNYWASH (Boston-New York-Washington, DC) corridor of the eastern ...
