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.

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.
