Earth Hour 2013 took place on Saturday, March 23-2013 in over 7000 cities, towns and municipalities in more than 150 countries and territories around the globe and again this year, Berlin was one of those cities.
Exact at 8:30pm, the Brandenburger Tor went black for a whole hour and during this hour Singer-Songwriter Ashley Hicklin performed his song “City Lights” unplugged and a neon sign, showing the slogan “Ja zur Energiewende!” was illuminated by a group of WWF Members riding bicycles.
