Earth Hour was born in Sydney, Australia in 2007, when 2 200 000 people turned their lights off during sixty seconds to draw attention on the need to face climate change. In its second edition, this WWF initiative became a global phenomenon with over 50 million participants in 370 cities. For 2009, the proposed target was one billion participants in one thousand cities and Peru participated for the first time.
On Saturday, March 28th, 2009 at 8: 30 pm from the pyramids of Egypt to the Beijing National Stadium, lights were turned off in a gesture of optimism to face climate change, involving nearly 4000 cities and over one billion participants. In Peru, 40 cities turned their lights off, authorities, artists and businessmen publicly joined the Earth Hour initiative and the most important commercial establishments, monuments, plazas, parks and cathedrals were left in the dark.
The official reading determined an impressive decrease of over 15 % in energy consumption nationwide during Earth Hour. In other words, 8 million Peruvians – or 1 in every 3 with access to electricity - turned their lights off, making it the most successful environmental campaign in our country and Peru into one of the countries with most participation and commitment to face climate change in Latin America and the World
