U-S Energy Secretary Steven Chu visits Metro Detroit today to tout the Obama Administration’s efforts in helping both the auto industry and the military. The Secretary is scheduled to tour the A123 Systems plant in Romulus, which makes batteries for electric vehicles. Company officials say they’ve hired a thousand new workers in Michigan, in part because of a nearly $250 million grant from federal stimulus funding. Chu is expected to highlight the Administration’s role in using stimulus money to help create jobs. Many Republican critics of the stimulus say it did little to stimulate the economy. The Energy Secretary will also address a workshop hosted by his agency and the U-S Army. The workshop is designed to find ways to enhance cooperation between Energy, the military and the private sector. Organizers say one example is creating more fuel-efficient military vehicles, which would lessen the need for long convoys of trucks carrying fuel to Army troops – convoys that are often targeted on battlefields.
