Gabe Klein is a key figure in the Biden administration’s plans to build out infrastructure for America’s future electric cars, buses and trucks. But his biggest accomplishment may involve bicycles.

In September, Klein, who has run transportation departments in Washington and Chicago, was named executive director of the new Joint Office of Energy and Transportation, which was created by the Bipartisan Infrastructure Law signed by President Joe Biden last November.

Just as the EV is a fusion of vehicle and an electrical appliance, the joint office fuses expertise from two federal agencies, the departments of Energy and Transportation. As far as anyone knows at DOE or DOT, it is the first joint office between government departments in U.S. history.
