• In Tel Aviv, Israel, a free concert by Knesiyat Hasekhel was held at Rabin Square. Power needed for the concert was generated by a group of cyclists pushing pedal generators. The rest of the power was supplied by generators burning used falafel oil for power.
• In Atlanta, the CEO of WWF US, Carter Roberts, and the Mayor of Atlanta, Shirley Franklin, flipped a giant switch on live TV, symbolically starting the wave of lights going out on the buildings around the city.
• In San Francisco, a public event hosted by WWF US was attended by Mayor Gavin Newsom, Gold medal figure skater Brian Boitano, Grateful Dead drummer Mickey Hart, and other celebrities. They gathered to watch the lights go out, listening to the music of Jason Damato.
