The Eiffel Tower Goes Green

Paris’s most iconic landmark gets a new, eco-friendly addition.

The Eiffel Tower, built in 1889, was created with the sole intention of acting as the entrance to the 1889 World’s Fair, meant to last only a few years. Paris’s most iconic landmark has seen various additions and decorations for holidays and events in its 126 year life span, but it’s latest renovation is a new symbolic and practical addition. Last week, Urban Green Energy, a renewable energy firm, installed two wind turbines near the second level of the tower within the metal scaffolding. The turbines will produce 10,000 kilowatts per hours, enough to offset all the electricity used on the first floor, which includes restaurants, a souvenir shop, and historical exhibits, in a given year.

According to CNET, the vertical axis turbines are installed 400 feet from the ground, a height meant to optimize the amount of wind (from any direction) captured. The turbines will not be a sight for sore eyes or ears either; they have been specifically painted to blend in with the tower and the sound produced by the turbines registers at about 40 decibels, or the sound of a whisper.

The tower’s architecture was better suited for wind energy rather than solar power. “Being up on the tower, it was very evident wind was the right choice,” Jan Gromadzki, an engineer for UGE, told Fast Company. “We're so far up above the rest of Paris that we actually get very strong winds, very powerful winds that can be used and harnessed to produce energy. Solar would have required quite a bit of space, which they really don't have on the tower. It would also look like glass, and they didn't want to cover any of the structure.”

Beyond practicality, the Eiffel Tower’s newest addition will serve as a symbol for renewable energy. Paris has enacted greener policies recently as it looks ahead to the end of 2015 when it will host a global summit on climate change. The city’s sustainability goals include powering all municipal buildings and public lighting using electricity from renewable resources by 2016 and banning all diesel vehicles within city limits by 2020. The latter goal was presented as a plan by Mayor Anne Hidalgo in an attempt to reduce the city’s air pollution. With installing unobtrusive wind turbines on the city’s most famous building, Paris is looking to encourage other cities and people to consider utilizing green technology.

“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 told the Verge. “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.”

The phrase "stay in your lane" is usually lobbed at celebrities who talk about politics on Twitter by people who disagree with them. People in the sports world will often get a "stick to sports" when they try to have an opinion that lies outside of the field of play.

The Free the Nipple movement is trying to remove the stigma on women's breasts by making it culturally acceptable and legal for women to go topless in public. But it turns out, Free the Nipple might be fighting on the wrong front and should be focusing on freeing the nipple in a place you'd never expect. Your own home.

In August, the Recording Academy hired their first female CEO, Deborah Dugan. Ten days before the Grammys, Dugan was placed on administrative leave for misconduct allegations after a female employee said Dugan was "abusive" and created a "toxic and intolerable" work environment. However, Dugan says she was actually removed from her position for complaining to human resources about sexual harassment, pay disparities, and conflicts of interest in the award show's nomination process.

Just five days before the Grammys, Dugan filed a complaint with the Equal Employment Opportunity Commission, and her claims are many. Dugan says she was paid less than former CEO Neil Portnow. In 2018, Portnow received criticism for saying women need to "step up" when only two female acts won Grammys. Portnow decided to not renew his contract shortly after. Dugan says she was also asked to hire Portnow as a consultant for $750,000 a year, which she refused to do.
