The BBC reports that the northern city of Hannover "has turned off the heating and switched to cold showers in all public buildings because of the Russian gas crisis."

This is a result of the war in Ukraine, and the resulting sanctions against Russia, which has in turn caused Russia to reduce supplies of natural gas to Europe.

Several cities in Germany have already taken action to reduce gas consumption; the action by Hannover is just one example.

The report also states "Other cities - such as Augsburg in Bavaria - have already introduced their own measures such as turning off public fountains." Well, that certainly doesn't include Munich (also in Bavaria), where public fountains are still running, as you can see from this photo, taken yesterday on Prinzregentenplatz.
