USPS OIG: Electric Delivery Vehicles and the Postal Service
"In this white paper, the OIG sought to identify opportunities and challenges in adopting electric delivery vehicles. We assessed the suitability of using electric vehicles as delivery vehicles and analyzed the potential long-term cost savings of a new electric delivery vehicle compared to a new gas-powered vehicle. We also benchmarked the electric vehicle experiences of other federal agencies, foreign posts, and companies in the logistics and shipping sector."
