In the summer of 2003, the structure was "dressed" in a new lighting outfit of 20,000 bulbs mounted on 40 km of wires. The new illumination, custom-made, cost the French treasury €4.6 million
The tower's lighting was last upgraded in 2015. To save electricity, the electric lights were replaced by LEDs. At the same time, two wind turbines, heat panels, and rainwater harvesting systems were installed.
On important days for the country or in honor of some public holidays, the Eiffel Tower is decorated with special color illumination. Thus, in 2008 (the year of France's presidency of the EU) it was illuminated for a while by the colors of the EU flag.
