The Eiffel Tower’s iron-clad frame turned slightly greener last week, with the installation of two new wind turbines along its lower deck. Perched some 400 feet above the ground, atop a ritzy, second-level restaurant, the slender turbines are part of a broader effort to make Paris’ most iconic monument more eco-friendly — even if only slightly.
When they go into operation next week, the 17-foot structures will provide enough electricity to power the tower's first-floor commercial areas — about 10,000kWh per year. Jan Gromadzki, an engineer who oversaw the project for New York-based Urban Green Energy (UGE), says that's enough to power an average American family’s home for one year. But for the Eiffel Tower — which consumes an estimated 6.7 GWh a year — “it's just a small drop in the ocean."
Paris has also embraced greener policies in recent months, ahead of hosting a global summit on climate change in December. The city recently called for all municipal buildings and public lighting to exclusively use electricity from renewable sources by the year 2016, and Mayor Anne Hidalgo wants to ban all diesel vehicles from Paris by 2020, in the hopes of easing its smog problems. The hope is that planting discrete wind turbines on the city’s most recognizable building will not only reaffirm Paris' eco-friendly agenda, but spur others to adopt similar technologies, as well.
"It really does represent this big leap forward for renewable energy as a whole, to have this technology to the point where it can be easily adopted by consumers like the Eiffel Tower," Gromadzki says. "And I think that was something that, five years ago, no one would've been ready for. It demonstrates that we’ve come this far to create renewable energy technologies that can be easily integrated into the daily lives of people around the world."
