Faced with record-breaking heat, Vietnam's capital Hanoi has turned off some street lights to save electricity as demand for air conditioning soars.
Parks in the city of eight million people are now plunged into total darkness after 11 pm, while two-thirds of street lights are also switched off at the same hour.
Scientists have warned that global warming is intensifying extreme weather events such as heatwaves.
In early May, Vietnam recorded its highest-ever temperature -- 44.1 degrees Celsius (111.38 degrees Fahrenheit) -- breaking a previous record set in 2019.
The country sweltered under a heatwave in April, and another in late May, and state electricity company EVN has warned that huge demand from air conditioners and fans has put the national power system under strain.
"I am worried about a power shortage, which may badly impact us during the hot summer," Hanoi resident Do Tung Duong said while on a walk in the dim city centre.
Another resident, Vu Thi Hoa, told AFP she agreed with the measure to cut public lighting.
"We should turn off unnecessary electric equipment, especially the lights. It feels hotter if there are too many lights on," she said.
"We need power for fans and air conditioners. It will be terrible if there is a power cut."
Public lighting is switched on half an hour later than usual, and turned off half an hour sooner.
Although some cuts are made to street lights every year, "the power saving scheme is in a wider area this year, covering 70 percent of the city's public lighting system," HAPULICO deputy director Le Trung Kien told local media.
"We still ensure enough lighting for traffic, security and order."
HAPULICO said the cuts may last until the end of August.
