Bangkok officials have called on residents to participate in Earth Hour 2026 by turning off non-essential lights and appliances from 8.30pm to 9.30pm on March 28. This initiative aligns the city with thousands worldwide, emphasizing energy conservation and climate action. The Metropolitan Electricity Authority (MEA) encourages involvement from Bangkok, Nonthaburi, and Samut Prakan communities.

Earth Hour began in Sydney, Australia in 2007, launched by WWF Australia to spotlight the climate impact of carbon emissions. It has since evolved into a global movement in over 190 countries, marking its 20th anniversary this year. Last year, Bangkok noted a significant reduction of 134 megawatts during Earth Hour.

The MEA will switch off non-essential lighting at its buildings to lead by example, urging households to follow suit. Experts highlight Earth Hour's power in raising awareness, although critics sometimes question its impact beyond symbolism. Still, it fosters community engagement and awareness.

Looking forward, the success of Earth Hour could inspire further initiatives for energy efficiency in the region. Continued participation can reinforce the importance of daily efforts in combating climate change, reported Bangkok Post.

The amount of energy that could be saved if hospitals, dentists, and doctor's offices would turn their AC thermostats from 19 to a comfortable 27.
Almost every visit I make to a doctor or dentist or a private Hospital, I need to put a coat on to stay comfortably warm. If I use my AC its to keep my room around 30C where I'm acclimatized. "Dim lights?" Modern lights are LED that draw very small amounts of power. AC's in Thailand - probably suck the lion's share. That and those Electric Vehicles that everyone's been urged to buy to "save the planet." Well, I'm glad EGAT here in Northwest Thailand still burns coal for energy. If electric skyrockets? Sucks to have an EV unless you have Solar Panels.

Earth Hour? Save Gaia? Right. How about moderating the use of energy 24/7?

The amount of energy saved if they stopped blowing stuff up in wars would be far more

not to mention the not killed innocent civilians who would not be dead..or the wasted energy rebuilding after the pointless war in the first place.
