This weekend people across the world will celebrate Earth Hour by turning off the lights for 60 minutes — sending a powerful message about our commitment to a sustainable future for the planet.

In Los Angeles, on Saturday, March 19 we will flip the switch at 8:30 p.m. We would love to mark the occasion together. The Mayor’s Office of Sustainability and the Los Angeles Department of Water and Power (LADWP) are co-hosting a community gathering at the John Ferraro Building (111 North Hope Street in Downtown L.A.). You are invited to come over and watch several L.A. landmarks — City Hall, the Central Library, downtown skyscrapers — go dark, to the sound of live music.

Our City has been an active Earth Hour participant for several years and 2016 marks our biggest effort to date. Thanks to a collaboration with City departments and partners like the Building Owners and Managers Association of Greater Los Angeles and the Los Angeles Better Buildings Challenge millions of square feet of office space will join the cause on Saturday.

Between the City’s own facilities -- LAX’s iconic pylons and the Port of Los Angeles’ famed Vincent Thomas Bridge will power down -- and the efforts of our community partners, including places like the Getty and Broad museums, Staples Center, and LA Live, we expect to save enough electricity in one hour to light over 100 homes for an entire month.

That is impressive, but the most meaningful impact comes from the participation of our residents. Though difficult to quantify, your combined participation will surely make a larger impact than the biggest building or tallest skyscraper.

And we can magnify that impact by remembering that this time is about more than just turning off the lights for 3,600 seconds; it’s an excellent opportunity to connect with our families, friends, and neighbors and talk about what steps we can take in our everyday lives to better protect the planet. After all, Earth Hour may end Saturday night at 9:30 p.m. — but our dedication to keeping our planet healthy should last a lifetime.
