Wind Energy Installations: New insight!
American Institute of Physics (AIP)
Researchers have developed a new way to study Wind Energy Installations wake effects that includes the airflow both within and around a wind farm and challenges the conventional belief that turbines arrayed in checker board patterns produce the highest power output. Their study provides insight into factors that determine the most favorable positioning.
s wind farms grow in importance across the globe as sources of clean, renewable energy, one key consideration in their construction is their physical design — spacing and orienting individual turbines to maximize their efficiency and minimize any “wake effects,” where the swooping blades of one reduces the energy in the wind available for the ing turbine.
Optimally spacing turbines allows them to capture more wind, produce more power and increase revenue for the farm. Knowing this, designers in the industry typically apply simple computer models to help determine the best arrangements of the turbines. This works well for small wind farms but becomes less precise for larger wind-farms where the wakes interact with one another and the overall effect is harder to predict.
Now a team of researchers at Johns Hopkins University (JHU) has developed a new way to study wake effects that takes into account the airflow both within and around a wind farm and challenges the conventional belief that turbines arrayed in checker board patterns produce the highest power output. Their study provides insight into factors that determine the most favorable positioning — work described in a new paper in the Journal of Renewable and Sustainable Energy, which is produced by AIP Publishing.

The intersection of the oil and gas and geothermal industries is one that is rich in unexpected ways, be it in drilling technologies or the new frontier of co-production of both fossil fuels and geothermal power from the same well.
Enel Green Power North America announced on Thursday that it has signed a power purchase agreement (PPA) between its subsidiary White Cloud Wind Project, LLC and Associated Electric Cooperative Inc. (AECI), a power utility based in Springfield, Missouri. In line with the agreement, AECI will purchase the entire output generated by the 236.5 MW White […]
CleanChoice Energy on Thursday said it was opening an additional 20.51 MW of community solar capacity for residential customers of Xcel. The new capacity is being supplied by fifteen solar farms owned and operated by AltusPower America in various locations in Minnesota. CleanChoice Energy is the largest community solar provider in Minnesota with more than […]
This week, Southern California Edison announced that it has signed on the first developer, SharedSolarCA, to its Community Renewables Program that will allow residential and business customers to take advantage of solar energy without having to install it directly on their roofs or facilities.
On Thursday this week, Mayor Steven Fulop welcomed EnBW North America to Jersey City in a ribbon-cutting ceremony. New Jersey Economic Development Authority Senior Vice President Brian Sabina and others gathered to officially open the German subsidiary’s first U.S. office and marking its entrance into the competitive New Jersey/New York offshore wind market.
Quantum Composers, designer and manufacturer of DPSS lasers, has announced an addition to their Jewel Laser Series, the MiniJewel Laser. This innovative new compact laser has a small footprint (165mm x 97mm x 36mm), weighs less than 3lbs, and is easily customizable. Mr. Will Bomar, VP of Sales clarified that “this will allow seamless integration… […]
Scientists have found a new way to control light emitted by exotic crystal semiconductors, and this finding might lead to more efficient solar cells as well as other advances in electronics, according to a Rutgers-led study in the journal Materials Today. The discovery involves crystals called hybrid perovskites, which consist of interlocking organic and inorganic… […]
