According to statistics on national electricity consumption of the National Electricity System and Market Operation Company Limited (NSMO), after 1 hour of turning off the lights in response to the Earth Hour Campaign 2025 (from 8:30 p.m. to 9:30 p.m. on March 22), the whole country saved 448,000 kWh of electricity, equivalent to about 942.2 million VND.
Earth Hour is one of the annual global events on environmental protection, with the response of many countries and territories.
The Earth Hour campaign in Vietnam, co-chaired by the World Wildlife Fund (WWF) in Vietnam and the Ministry of Industry and Trade, attracted the attention and response of 63 provinces and cities and many people from all walks of life.
Vietnam Electricity Group (EVN) is one of the typical units, always actively cooperating to effectively implement the program. 2025 marks the 17th time Vietnam has participated in this campaign.

With the spreading effect of the Earth Hour event, promoting the implementation results over the years, the Ministry of Industry and Trade launched the movement "All people save energy in response to Earth Hour 2025" with the message "Green transition - Green future".
The movement does not stop at calling for electricity saving, but also aims at a broader goal of encouraging sustainable energy production activities, increasing the use of renewable energy, promoting the application of energy-saving products and equipment, contributing to improving energy efficiency in both economic and environmental aspects.
After many years of active participation, the Earth Hour campaign in Vietnam has spread strongly across the country, becoming a meaningful annual activity taking place every March.
