The Benefits of Smart Grid Technology for Buildings, Cities, and Sustainability


Published on

June 15, 2011

Audrey Zibelman's presentation from America’s Sustainable Future: How U.S. Cities Are Making Energy Work, an invitational conference of public-private partnership efforts from U.S. cities pursuing innovative energy management and smart grid initiatives. The assembled leaders in industry, research and policy-making will explore the diverse energy strategies emerging in Philadelphia and across the United States.

“We’re really looking forward to both learning from the great examples set by other cities represented in the conference, and showing off the groundbreaking work happening right here in Philadelphia,” says Laurie Actman, Viridity Energy’s director of strategic partnerships and public policy.

“With smart ideas and smart policy, we should be able to build support for smart grid projects and microgrids at the federal, state and local level.”"Energy technology is changing at such a rapid pace, it's crucial to examine who's doing it right in smart grid and microgrid projects all around the country," says Eugenie Birch, Penn IUR co-director.

"With the right policy moves—which we'll be exploring at the conference—Philadelphia can be a national leader in energy innovation," noted Susan Wachter, Penn IUR co-director.
