Five Energy and Environment Executives in Government Contracting

The departments of Energy and Transportation recently invested $5 billion in the buildout of a national electric vehicle charging infrastructure, with a focus on increasing charging access for rural, disadvantaged and hard-to-reach locations.

According to the DOE, the investment is part of the Biden administration’s larger effort to halve the United States’ greenhouse gas pollution from 2005 levels by 2030. The president also aims to fully decarbonize the American economy by 2050, according to a White House fact sheet.

The Potomac Officers Club—a division of Executive Mosaic—features five executives supporting the government’s energy and environmental goals.
