Innovative wind towers won't harm eagles
Wind farms killed about 573,000 birds in the United States last year, according to the Wildlife Society. Since 2008, there were more than 67 bald and golden eagles killed by wind turbines in the U.S., which does not include more than 60 eagles killed annually in California’s Altamont Pass, according to National Audubon Society.
To eliminate the risk for harming eagles or any wildlife there is now a new wind system called INVELOX –patented by SheerWind Inc. – that takes the spinning blades of a turbine out of the sky and puts them safely at or below ground level.
Not only does it eliminate the immediate issue of birds flying into the blades, it also puts an end to the issues from low frequency airborne vibration from the large turbine blades that have a negative influence on humans, wildlife, and livestock.
“This technology with no rotating blades at the top of a tower, will not harm eagles or any feathered friends," says Cyndi Lesher, SheerWind's executive VP and chief administrative officer and former president and CEO, NSP an Excel Energy Co. “By concentrating and accelerating wind, we create a similar effect to the natural wind corridors used by traditional wind towers.
“We can also install in low wind conditions, and close to human populations – safely out of the range of eagle flight patterns and nesting sites. With careful design and planning, who knows, the eagles may find an INVELOX tower the perfect place to build a new nest.”

INVELOX technology has been reviewed and validated by a technical advisory board, a team of experts from major research universities and agencies. Prototypes were tested under controlled laboratory conditions, and test results were used to build and validate full-scale computational fluid dynamic models. Field data collected to date has validated results.
The technology requires no subsidies, is price competitive with traditional energy, and has far less environmental impact than turbine-topped towers.
“This is just the beginning,” says Lesher. “INVELOX is a deep rethinking of wind harvesting and will change the course of power generation.”
In 2009, the U.S. Fish and Wildlife Service began a permitting program under the Bald and Golden Eagle Protection Act applicable to developers of renewable energy projects and other activities that may “take” (injure, kill or otherwise disturb) bald and golden eagles. The Eagle Act allows the Service to authorize the programmatic take of eagles, which is take associated with, but not the purpose of, an otherwise lawful activity and does not have a long-term impact on the population.
These permits have been for a maximum of five years – a period that does not reflect the actual operating parameters of most renewable energy projects or other similar long term project operations. The recently revised rule, a result of extensive stakeholder engagement and public comment, extends the maximum permit tenure to 30 years, subject to a recurring five-year review process throughout the permit life.
UK Nissan fleet owners receive commercial charging service
UK fleet owners of Nissan Leaf and e-NV200 models can avail of a new commercial charging service using vehicle-to-grid (V2G) technology.
The V2G technology developed by DREEV, which is a joint venture between EDF and Nuvve, which specialises in V2G technology, allows for two-way energy flow; both recharging an EV’s battery when electricity is at its cheapest, and discharging excess energy to sell back into the grid.
Fleet customers will save around £350 savings per charger each year, which equates to approximately 9,000 miles of driving charge per year.
EDF’s V2G business solution includes:
The supply and installation of a two-way connected compact 11kW charger capable of fully charging a Nissan LEAF, depending on the battery model, in 3 hours and 30 minutes - 50 per cent faster than a standard charger - with integrated DREEV technology.
A dedicated DREEV smart phone app, to define the vehicles’ driving energy requirements, track their state of charge in real time, and control charging at any time
Philip Valarino, Interim Head of EV Projects at EDF, said today’s announcement marks an important step on the UK’s journey towards electric mobility. "By combining the expertise and capabilities of EDF, Nissan and Dreev we have produced a solution that could transform the EV market as we look to help the UK in its journey to achieve Net Zero," he said. “Our hope is that forward-thinking businesses across the country will be persuaded to convert their traditional fleets to electric, providing them with both an environmental and economic advantage in an increasingly crowded market.”
Andrew Humberstone, Managing Director, NMGB, said Nissan has been a pioneer in 100% electric mobility since 2010, and the integration of electric vehicles into the company is at the heart of Nissan's vision for intelligent mobility.
He added the Nissan LEAF, with more than half a million units already sold worldwide - is the only model today to allow V2G two-way charging and offers economic opportunities for businesses "that no other electric vehicle does today". Click here for more information.
FirstEnergy Corp, which aims to electrify 30% of its approximately 3,400 light duty and aerial fleet vehicles by 2030, has joined the Electric Highway Coalition. The group of electric companies, which has grown to 14 members, is committed to enabling long-distance EV travel through a network of EV fast-charging stations connecting major highway systems.
The Edison Electric Institute estimates 18 million EVs will be on US roads by 2030. While many drivers recognize the benefits of driving an EV, some are concerned with the availability of charging stations during long road trips. Through their unified efforts, the members of the EHC are addressing this "range anxiety" and demonstrating to customers that EVs are a smart choice for traveling long distances as well as driving around town.
Volta Industries has installed new charging stations at Safeway in Upper Marlboro, Maryland, and Renton, Washington.
