Former government official and current partner with the Silver Lake Kraftwerk green technology investment firm, Cathy Zoi commands a long history of successfully bringing innovations in energy and environmental protection to market, as well as to the forefront of government agendas. During her career, Cathy Zoi held high-profile federal positions with two U.S. administrations. 

Cathy Zoi most recently served as a Senate-confirmed Acting Under Secretary for the Department of Energy (DoE) and Assistant Secretary for Energy Efficiency and Renewable Energy from 2009 to 2011. In this position, she was responsible for overseeing several DoE programs, including the Offices of Environmental Management, Nuclear Energy, and Electricity Delivery & Energy Reliability. Zoi was recruited to the DoE from the nonprofit sector, where she worked as a founding CEO of the Alliance for Climate Protection, a nonpartisan group co-established by former Vice President Al Gore in 2006 and dedicated to climate change education and response. 

During the Clinton-Gore administration, Cathy Zoi helped improve federal energy and environmental policies as head of the White House Office on Environmental Policy and as a Manager with the Environmental Protection Agency (EPA). While working for the EPA, Zoi helped found and promote the international Energy Star rating program, which has since become a standard in producing and identifying energy-efficient products and buildings. 

Within the private sector, Cathy Zoi has led several energy-focused organizations. She worked as an Executive Director with The Bayard Group (now known as Landis+Gyr), a Swiss company involved in energy metering and similar technologies. Zoi also founded and served as CEO of the New South Wales, Australia-based Sustainable Energy Development Authority. With the latter organization, she helped invest millions of dollars in commercial greenhouse-friendly innovations.
