Earth Hour was famously started as a lights-off event in Sydney, Australia in 2007. Since then it's grown to engage more than 162 countries and territories worldwide. Earth Hour is much more than just switching off your lights for an hour; it promotes the idea that individuals can make a difference, no matter how small or big. You can get involved in the worlds largest environmental movement by turning off your lights for an hour (or the whole night), attending or hosting one of the many events, and by making the pledge to switch to renewable energy.
