Two wind turbines have been successfully installed on the Eiffel Tower to offset some of the structure’s energy use, renewable energy company UGE and the public service authority in charge of the iconic landmark announced this week.
The two turbines, which were placed 400 feet above ground level, are expected to produce 10,000 kWh annually. This will offset the power used by commercial activities on the tower’s first floor, according to UGE. The turbines are of the vertical axis variety, as opposed to the larger and more common horizontal axis turbines that rotate like traditional windmills, and they are painted to match the tower.
The project is part of a larger efficiency upgrade that also includes LED lighting and rooftop solar panels on a visitor pavilion.
LED lights have illuminated Rio’s famous mountaintop statue of Christ since 2011.
Sydney Opera House
The Sydney Opera House has implemented several steps to improve the facility’s sustainability, including more efficient air conditioners and lighting, along with a cooling system that uses seawater and saves millions of gallons of drinking water annually.
