he turbines took place 122 meters above the ground, on the second level of the building. A location designed to allow better wind absorption and thus maximize their performance. These VisionAIR5 vertical wind turbines are capable of beating the wind coming from any direction. The yield is substantial as they can produce nearly 10 kWh per year, which would be enough to power the entire first floor of the tower.
Of course, the company could not simply install this equipment, it had to meet special requirements due to the unprecedented location of these turbines. Wind turbines are neither visible nor audible. With more than 7 million visitors since its creation, the monument cannot be disturbed by noise pollution or even by the appearance of two wind turbines in this postcard landscape. Thus the blades have a particular movement which makes no noise. In addition, the color of the wind turbines has been specially chosen to perfectly match the decor of the tower. These two wind turbines are therefore both useful and imperceptible.

"It's quite symbolic", we recognize in the Company operating the Eiffel Tower. But they mark the Tour's "commitment to sustainable development". The two vertical axis wind turbines blend into the structure of the "iron maiden", with their color between gray and taupe. The initiative is in addition to other eco-friendly efforts of the most visited paid monument in the world: fully Led type lighting, solar panels on one of its pavilions, rainwater recovery, heat pumps, electricity supplied by the Grenoble-based company GEG, "to supply the monument with 100% renewable energy", adds SETE.
The annual electricity consumption of the Tower is 6.7 GWh, that of a city of around 3.000 inhabitants.
The Tower received 7.0976.302 visitors in 2014.
Off Fukushima, the world's largest floating wind turbine
By Anne-Katell Mousset - Usine Nouvelle on August 04, 2015,
In pictures: Japan has just installed a giant floating wind turbine 100m high, a few kilometers from its coast, capable of withstanding tsunamis.
Off Fukushima, the world's largest floating wind turbine has just been installed, reports NBC News. With its 7 MW of power, the latter is weighted by four 20-ton anchors nearly 20km from the coast. The structure measures more than 100 meters in height in order to withstand possible 20-meter waves or tsunamis.
This wind turbine is part of a national government plan to create the world's first offshore wind farm. Objective: to study the economic feasibility of wind energy as an alternative to nuclear, explains NBC.
10 companies are involved in this project, including Shimizu Construction and Mitsubishi Heavy Industries.
China wind energy capacity now stands at 105.53 GW
July 27, 2015 evwind
China connected an additional 9.16 gigawatts (GW) of wind power to its grid in the first half of 2015, according to figures published by China's top energy regulator on Monday, raising the total by 9.5 percent compared to the end of last year.
Total grid-connected wind capacity now stands at 105.53 GW, the National Energy Administration (NEA) said.
110 million euros for the Seine-Rive gauche-Nord wind farm
By PHILIPPE SCHILDE - Usone Nouvelle on September 17, 2015,
Located between Troyes and Romilly-sur-Seine (Aube), the third most powerful wind farm in France (75 MW of installed capacity) was put into service during the summer by the developer H2air and the turbine manufacturer Nordex on behalf of the KGAL investor.
In France, onshore wind farms have an average of seven or eight machines. The Seine-Rive gauche-Nord (SRN) farm, inaugurated on September 11 in the Aube region of the municipalities of Châtres, Mesgrigny, Orvilliers-Saint-Julien and Vallant-Saint-Georges, lists thirty 2,5 MW each, planted in the middle of the grain plain. 150 meters tall (pale included) and equipped with the latest technologies, these wind turbines are capable of producing 183 MWh / year of green electricity, covering the needs of 000 households, excluding heating.
This is "clean and inexpensive" energy, according to the managers of the Picardy company H2air (developer and managers of wind farms) and of the French subsidiary of the German group Nordex (turbine manufacturer and maintenance operator) who came to emphasize the originality of this "flagship operation" carried out in partnership (co-design and co-realization) on behalf of the investor KGAL Investment Management. The amount of the investment is estimated at 110 million euros. About 300 people, mostly from regional companies, worked on this site, which lasted a year.
PRIVATE CONNECTION STATION
Both Catherine de Tourtier, President of Nordex France, and Roy Mahfouz, founder of H2air, have insisted on the importance of building large-scale parks to meet national objectives in terms of renewable energy production. The ambition displayed by the State is to reach 23% of electricity consumption by 2020 before climbing to 32% by 2030.
The operators of the project believe that the SRN fleet alone should save 73 tonnes of CO000 per year, but they insist on the regulatory constraints which slow down the hoped-for developments. On land suitable for wind power in Champagne-Ardenne, region number 2 for this activity in France (1 MW of power connected to the grid out of the 1 MW provided for in the regional plan by 595), they had to remove two obstacles, in particular.
The first was to obtain authorization to build a private connection station. This installation, which brings together the energy produced by the thirty wind turbines (with an output voltage each of 20 volts) and raises the voltage to 000 volts to inject energy into the RTE network, is a case in point. quite rare in France. "We had to discuss with the electricity distributor ERDF and obtain authorization from the Dreal. In the end, with this private station, we managed to better control deadlines and costs", observes Roy Mahfouz, hoping to be able to repeat elsewhere this type of operation.
IN THE FIELD OF MILITARY RADARS
The second major negotiation that H2air and Nordex had to conduct was with National Defense. The SRN park is located only a dozen kilometers from the Prunay-Belleville (Aube) radar station, which depends on Saint-Dizier Air Base 113 (Haute-Marne).
"It was not easy, but we found common ground with the Defense. Above all, to limit the risk of disturbances (interference) we respected a perfect alignment of our machines, with very precise angles. We are proud of the solution currently in operation, which symbolizes the possibility of cohabitation between military radars and wind turbines ", underlines Catherine de Tourtier.
Poma diversifies in the onshore wind industry
September 30, 2015 actu-environnement.com
The French group Poma, designer of cable transport solutions, is diversifying into the onshore wind industry, he announced on September 29. Poma, via its subsidiary Leitwind, manufacturer of wind turbines, will build an assembly site in Rhône-Alpes which will produce "multi-megawatt" onshore wind turbines from 2017. The nacelles, generators and power converters will be assembled there.
Leitwind has installed more than 300 wind turbines worldwide, with rotors from 70 to 101 meters in diameter and unit powers up to 3 MW. In 2014, Poma's turnover amounted to 290,6 million euros.
