The Earth Hour has become the most popular mobilization campaign for the protection of the environment in the past years.
In 2014, more than 7,000 cities in 150 countries turned off the lights of their main monuments and emblematic buildings to send a message: small gestures can generate large changes.
Bet on efficiency and reduce your energy consumption, reduce CO2 emissions.
Next March 28, from 8:30pm to 9:30pm turn off the light.
