‘Light Up the Night’: Ecology-minded celebrities and community leaders turned out Saturday night to launch Empowered by Light, a nonprofit foundation working on delivering renewable-energy lighting to rural communities in Africa. The party, held at Roe in San Francisco’s South of Market area and co-hosted by actor-activist Adrian Grenier and Peter Glatzer, raised more than $100,000 for the organization’s first project, Solar: Zambia.
