The Eiffel Tower is going to go dark early as the French capital tries to save energy.

Every day from dusk until 1 a.m. the tower is lit up.

The lights on the tower give the "Iron Lady" a golden glow. The 20,000 bulbs twinkle for five minutes at a time.

The tower's lights are expected to be turned off more than an hour before the last visitors leave to save electricity.

The head of the tower's management told The Guardian that it was a symbolic gesture.

4% of the tower's annual energy consumption is accounted for by the nighttime lighting.

As countries prepare for the coming winter, the reduction of city illumination is seen as a way of setting an example. Insider has reported that Russia's Gazprom has stopped sending natural gas to France because of a payment dispute.

The Pharo Palace will be one of the monuments that will be turned off from the end of September.

There are other cities that are aware of energy consumption. Cities in Germany turned off lights to save energy.

After Queen Elizabeth II died, the Eiffel Tower went dark. Following terrorist attacks in Paris, the tower's lights were turned off.
