The Eiffel Tower is set to fall dark over an hour earlier, under new energy sobriety plans announced by Paris mayor Anne Hidalgo today. While the city council will be switching off its own grand home of Hôtel de Ville from 10pm as an example to residents.

It follows a raft of national measures from President Macron, who last week called for a 10 per cent reduction in energy use to avoid the risk of rationing this winter.

Most of the country's energy comes from nuclear, but with half of its reactors currently offline, France is seeking alternative supplies including electricity from Germany which is facing a severe gas shortage after Russia stopped its supply.

In stark contrast to the UK, Macron is fully renationalising state-owned electricity provider EDF, and continuing to cap energy prices at 4 per cent for consumers.

But the calls for "collective sobriety" in energy use in France are getting louder.

Where is Paris turning lights off?

The Eiffel Tower is typically illuminated until 1am by an elaborate lighting system that creates the iconic golden glow. Parisians are also used to an hourly twinkle from the tower at night, thanks to 20,000 flashing bulbs.

While monuments around the globe lit up with a British flag in honour of Queen Elizabeth's death on Thursday, Paris's most famous monument went dark in homage to Her Majesty.
