Earth Hour Wrap-Up 2013

Most of the Sydney Opera House was turned off - except for some green lights powered by renewable energy - as part of Earth Hour Australia's theme of Switch on to renewable energy.


With more than 7000 cities taking part, Earth Hour has an inspiring summary - including stories from India, Libya, Taiwan, Indonesia, Malaysia, Vietnam and Jamaica.


First-timers included Palestine, Suriname, Rwanda and Tunisia. Also for the first time Russia's Kremlin turned out the lights.
