  • Spin Doctors: How GE’s Service-Savvy Approach Squeezes the best from a fleet of 900 Wind Turbines

    Over 150 years ago, a budding English economist named William Stanley Jevons warned that a policy of energy efficiency might not be sufficient to conserve Britain’s dwindling coal reserves. His argument, now known as the Jevons paradox, was simple: Squeeze more energy from less coal, and people will just want more coal. ...

  • Ultrasonic wind sensor for smart wind turbine control - Polaris / USA - Case Study

    The American wind turbine manufacturer Polaris trusts for their wind turbine applications anemometers from Lufft. Over 50 wind turbines have already been equipped with our ultrasonic anemometers Ventus-UMB and V200A-UMB. Crucial in these applications is a high degree of precision and a long, maintenance-free useful life. In addition, controlling of the turbine complex requires a high frequency of ...

  • Mechanical vs. Ultrasonic Anemometers for Wind Turbine Control

    What do you think? Does the replacement of mechanical wind sensors trough ultrasonic anemometers in wind turbine control pay off after less than a few years? Free Cost Benefit Analysis about Replacement of Mechanical Wind Sensors Anemometers are vital components of utility-scale wind turbines and determine the performance of the turbine’s ...

  • 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 ...

  • What can blockchain do for the environment?

    “A lot of crypto-currency proponents say that blockchains are going to save the planet. Well, I just can’t see it.” This is not the resounding endorsement you might expect from widely acknowledged blockchain expert Michael Mainelli for the technology most famously associated with the internet-based currency known as Bitcoin. ...

  • Case study - Use of the Nor848A acoustic camera on wind turbines

    The acoustic camera system Nor848 is a powerful tool to investigate noise sources. In realtime you listen to a beamformed audio signal so that you can hear individual sources one by one. Immediately you can identify the strongest over all noise source in a multisource environment, and you can do the same analysis for single frequencies, 1/3 or 1/1 octave bands or any given frequency range. This ...

  • Change is the only constant

    2016 was a year of big changes for Lufft: A change in the ownership structure took place in January and in August I took the reins as the new Managing Director. After more than 100 days at the innovative measuring technology manufacturer with a long company history, I would like to share with you my experiences and impressions in the new position. What characterizes Lufft? A good mix! ...

  • 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 ...

  • Africa’s green energy challenge: Mega projects, off-grid or somewhere in between?

    South of the Sahara, getting electricity to 620 million people may require an all-of-the-above strategy. A 310-megawatt wind farm sprouting up in a remote, barren landscape near Lake Turkana in northern Kenya has the clean energy world buzzing — and for good reason. Africa’s largest wind farm, with 365 towering turbines, is creating more than 500 stable jobs in an ...

  • Does Wind Turbine Blade Length Really Matter?

    Simply put: Longer wind turbine blade length means greater power production. Blades capture the wind which forces the rotation of the rotor; longer blades means more area for the wind to push against, which means greater force and rotational power. However, how much difference does blade length make overall, in comparison to other factors? There is a standard formula that can be used to apply the ...

  • What’s the Future of R&D in the Wind Industry?

    When the wind industry finally reacted to the world’s financial crisis—it didn’t fully hit us until 2010—at once, we lost both an incredibly vibrant global wind market and sufficiently robust profit margins. The market recovery is rebounding nicely now, thanks largely to government incentives, but profit margins will probably never fully recover—at least, not to 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 ...
