In view of the energy crisis in Europe, the lights of all historical places in Berlin, the capital of Germany, were turned off at night.
According to the news agency AFP, a campaign has been launched at the national level in Germany to deal with the shortage of gas supplied from Russia and to save electricity.
In this regard, around 200 important buildings, including the Charlottenburg Palace and the official Oprah House in Berlin, will be kept dark at night.
Bettina Jarsch, Berlin's chief environmental officer, has said that in the context of the ongoing war against Ukraine and Russia's energy threats, it is important that we use energy carefully.
Green Party member Bettina Jarsish's office says the policy will turn off 200 buildings and 1400 spotlights over the next four weeks.
German President Frank Walter said this week that the exterior of the presidential palace will also remain dark to set an example for the public.
To combat rising gas and electricity prices, the German chancellor has launched a national energy-saving campaign, while the European Union has also agreed to cut gas consumption.
EU officials have warned that Russia could cut gas supplies to Europe this winter in response to economic sanctions imposed during the Ukraine war.
Germany emphasizes minimum use of air conditioning and maximum use of public transport.
Before the Ukraine war, Germany used to buy 55% of its natural gas from Russia, but in June this amount has decreased to 35%.
Europe says dependence on Russia for energy is being used as a 'weapon' by Moscow.
