First there is the scenery, with this exterior view of a huge ball projecting spectacular images in the middle of Las Vegas. Inside, a dome covered with LED panels on 15,000 m2 with this room with a bird's eye view and breathtaking special effects. The Sphere, this futuristic 17,500-seat theater inaugurated on September 29 with the concert of U2 in front of stunned spectators, offers an extraordinary experience. Never seen before. But there is also behind the scenes... With its million LEDs, The Sphere is also a huge energy sinkhole. With its 95,000 MWh consumed in one year, the Las Vegas ball devours the equivalent of what 20,000 French homes consume in electricity in a city like Valenciennes.

Highly criticized on social networks for its energy cost, The Sphere cost more than 2 billion euros and can accommodate 18,000 people. However, its designers say they want to provide 70% of the room's electricity through solar. A goal set over 25 years.
