  • 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 ...

  • 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 ...


  • 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. ...

  • On the application of miniSoDAR technology to wind energy

    Introduction In the late 1990’s wind turbines with nacelle heights exceeding 60 meters were introduced to the wind energy community. Initially, wind prospecting and siting studies continued to use 50-meter wind towers and extrapolate the measurement to the nacelle heights. It was quickly determined that this approach was not sufficient for the placement of these tall turbines. The next ...

  • Community Wind Power for Renewable Income

    CONSIDERING its incredible history and environmental benefits, wind power is one of the most underutilized sources of renewable energy. Stretching back as early as 200 BC, communities have been harvesting the wind for power. However, the scale and popularity of wind power is only now starting to reach critical mass as concerns of climate change rise and energy usage continues to soar. While ...

  • 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 ...

  • Palmdale Water District Wind Turbine Project

    In response to the 2001 California energy crisis, Black & Veatch acted as the owner's engineer through the construction and commissioning phases of the largest net-metered wind energy project in the United States. The California energy crisis in 2001 made headlines around the world. The country's most populous state was caught in a power delivery squeeze and was beset with runaway ...

  • How much wind is needed to power a home turbine?

    First do you have what it takes? Whether you are considering a small rooftop unit or a large residential turbine you need to know how much wind power is in your area. Wind resource maps, published by the US Department of Energy show airflow speeds at 50 meters (150 feet) above the ground and are a great resource in deciding if you are in a viable location. That's great if you are installing a ...

  • 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 ...

  • Innovation risk slows offshore wind foundation development

    As offshore wind technology develops ever more gigantic machines further from shore into deeper waters, it is common wisdom that new foundation technologies are needed. But are they? Monopile, and some jacket foundations, still dominate the offshore wind market in commercial operation. Prototype floating foundations are performing well in demo or pilot projects, but scaling up is only ...

  • CU-Boulder leading study of wind turbine wakes

    While wind turbines primarily are a source of renewable energy, they also produce wakes of invisible ripples that can affect the atmosphere and influence wind turbines downstream -- an issue being researched in a newly launched study led by the University of Colorado Boulder's Julie Lundquist, assistant professor in the atmospheric and oceanic sciences department. The study, called the Turbine ...


  • Does Ultrasonic Wind Sensor VENTUS-UMB pass extreme tests?

    Sometimes we give our sensors a hard time. But this has a good cause: We want to guarantee the high quality and the keeping of our promises. A few weeks ago, the ultrasonic wind sensor VENTUS was the one to be challenged. We exposed the modern measurement device to extreme conditions. But did it endure these conditions? And where occurs enough wind to challenge the strong sensor at all? Wind ...

  • Contemporary approach to determination of magnetic induction in wind generator air gap

    Abstract The paper describes a system for measuring of magnetic induction on the wind generating unit. The manner of operation and the application of the Hall effect probe are detailed. Dynamic electromagnetic field computing results are shown through application of MKE on the synchronous generator model installed in a windmill unit and compared to the actual metering results. Two subsequent ...

  • Offshore wind installation vessel capacity to tighten after 2020

    The existing fleet of turbine and foundation installation vessels is well suited to serve the European offshore wind market in the short and mid-term but it will not be sufficient to support installation demand after 2020, Michael Guldbrandtsen, senior consultant at MAKE Consulting, told Wind Energy Update. The next 2-3 years will continue to be dominated by orders for jack-up ...

  • The price of wind energy in the U.S. hits an all-time low

    States hoping to increase their share of renewable energy to achieve the emissions reduction goals set forth in the President’s recently-announced Clean Power Plan may have just received an unexpected boost from wind energy. According to the U.S. Department of Energy’s ...

  • Air Flow Meters to Measure Air Velocity and Air Pressure

    Air flow meters are used to measure air velocity and air pressure. Depending on the type of application, air flow meters are made as hot-wire air flow meters or pocket weather flow meters, both of which can measure air velocity and air pressure. The results of measuring the air velocity can be stored in the memory of the device depending on the model. There are even data loggers for air velocity ...
