BANGKOK, Thailand – Bangkok has reported a substantial drop in electricity usage during Earth Hour 2025, with the city saving 134 megawatts of power in just one hour on Saturday night (March 22). Organized by the Bangkok Metropolitan Administration (BMA), the “60+ Earth Hour 2025” campaign encouraged residents, businesses, and institutions to switch off non-essential lights and appliances from 8:30 p.m. to 9:30 p.m., aligning with global participation across more than 7,000 cities in 190 countries.
Key landmarks across the capital, including the Grand Palace, Wat Arun, the Giant Swing, Rama VIII Bridge, and the Golden Mount, went dark during the hour to signal Bangkok’s support for climate awareness. The Metropolitan Electricity Authority reported that this short period of reduced consumption led to savings of over 621,000 baht and prevented an estimated 58.6 metric tonnes of carbon dioxide emissions.
The BMA praised the public’s involvement and described the campaign as part of its ongoing environmental strategy. Over the past three years, Bangkok’s participation in Earth Hour has saved a combined 138.65 megawatts and cut 36.2 tons of carbon emissions. The events have continued since 2008 and involve cooperation with government departments, private companies, and local communities.
Simple practices such as unplugging devices, reducing air conditioning use, turning off lights, cycling or walking, and using public transport were promoted as long-term habits that collectively reduce emissions and energy consumption. While Earth Hour is a symbolic event, Bangkok authorities see it as a starting point for broader environmental action. (NNT)
