Moscow saved 399 megawatt of electric power in the Earth Hour worldwide event, Moscow fuel and energy department chief Pavel Livinsky said on Saturday.
"Fifteen megawatt were saved by switching off illumination of more than 800 buildings," Livinsky said.
He called on Muscovites to be economical on a daily basis.
"The city is carrying out an energy saving program, and energy saving behavior is one of its goals. You do not have to deprive yourself of comfort, it would suffice to use resources to the benefit of your budget," the department chief said.
Lights were turned off throughout the Kremlin to observe the annual Earth Hour. The only illumination left was that of the president's banner hoisted above the residence of the chief of state and ruby-glass stars on top of Kremlin towers.
The illumination was switched off for one hour along the Red Square perimeter, including walls of the History Museum, the GUM department store, St. Basil's Cathedral and the Alexander Gardens. The Unknown Soldier's Tomb eternal flame was on.
The House of Government on Krasnopresnenskaya Embankment joined the Earth Hour action, too. Exterior illumination with the exception of the state flag illumination on the roof and some of the interior lights were switched on.
Earth Hour is the most massive public event ever. It is annually supported by hundreds of countries, several thousands of cities and more than 2 billion people.
