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.
