Jakarta will switch off lights on major roads and landmarks like Monas and the Welcome Statue for one hour on June 13 from 8:30 to 9:30 PM. The move is part of World Environment Day 2026 and aims to reduce electricity use and carbon emissions. The DKI government says a similar blackout in April saved 96.91 MWh of electricity, cut costs by IDR 140.2 million, and reduced emissions by 77.53 tons of CO2 equivalent. This is a symbolic but measurable effort. The savings numbers are specific, which helps show that even small collective actions can add up. The article also mentions Governor's Instruction Number 14 of 2021 as the policy basis, so this is a recurring program, not a one-off. The real question is whether these one-hour events actually change daily behavior or just check a box. Still, the data gives a concrete benchmark for what a coordinated citywide outage can achieve.
