Beginning at 8.30pm on Saturday, Earth Hour will be observed for an hour, during which people have been urged to switch off all non-essential lights and electrical appliances.
"BSES takes multiple steps to promote Earth Hour. SMSes are being sent to over 10 lakh customers, Earth Hour documentary is being screened at RWA meetings and posters are being displayed at offices and disseminated to RWAs," the statement said. All non-essential lights will also be switched off in the BSES offices, it added.
According to the statement, during the last Earth Hour observance in 2010, Delhi saved over 300 MW of power.
Delhi will join nearly a billion people in Mumbai, Los Angeles, London, Hong Kong, Sydney, Rome, Manila, Singapore, Dubai and over 6,000 other cities in 130 countries. "The message of the Earth Hour this year is to go beyond the hour, and commit to a more sustainable way of living, everyday and not just for an hour. It calls for individual action - albeit small - to sustain commitments and responsible actions beyond the hour," it said.
