The Eiffel Tower goes green, two wind turbines installed on the iconic monument

Two wind turbines have been installed on France’s most iconic site, the Eiffel Tower, as part of the famous tower’s extensive green retrofit project. In addition to wind energy, the renovation also includes LED lighting and 10 m² of roof-mounted solar panels on a visitor pavilion whose output will meet approximately 50% of the water heating needs of the two pavilions.

The two wind turbines, located about 120 meters up in the tower, are capable of delivering 10,000kWh of electricity annually, which is equivalent to the power used by the commercial areas on the Eiffel tower’s first floor.

"The Eiffel Tower is arguably the most renowned architectural icon in the world, and we are proud that our advanced technology was chosen as the Tower commits to a more sustainable future," said Nick Blitterswyk, CEO of Urban Green Energy (UGE), the US-based company which installed the wind turbines. "When visitors from around the world see the wind turbines, we get one step closer to a world powered by clean and reliable renewable energy."

The two UGE VisionAIR5 turbines are so-called vertical axis wind turbines, and these tend to have much lower production capabilities compared to the more traditional wind turbines. But UGE says the two wind turbines have been strategically placed on the Eiffel Tower so that their electricity generation can be maximized. UGE also add that these vertical axis wind turbines are designed to work in urban environments where both the wind’s speed and direction can be less predictable.

The wind turbines have been painted in a brown-grey hue to match the Eiffel Tower's frame and the company says the two turbines will be “virtually silent”. The turbines, which are only accessible through a restricted staircase, are located in the southwest corner of the Eiffel Tower, overlooking the Champs de Mars.
