The Danish government has urged its citizens to cut shower time and dry their laundry outside in an effort to save energy after Russia cut off its gas supply.

Denmark wants to save €3.4 million with advice for households to reduce energy consumption. It is also recommended to remove plugs from sockets when people go on summer holidays. Households account for approximately 29% of gas consumption in Denmark.

“We hope that with this campaign, Danes will reduce their energy consumption, with benefits for their own wallet, the energy supply situation and the climate,” the agency said.

Denmark has been cut off from Russian gas because the Danish energy company Ørsted refused to pay in rubles. The country will receive additional gas from Norway in October via a new pipeline.

Other European countries have also called on citizens to save as much energy as possible by, for example, taking shorter showers, turning down the heating, and using more energy-efficient LED lamps.
