So how many trucks/vans do you have on the road? Two, ten, 100? Think it's going to be expensive to replace them with alternative fuel vehicles? Chin up, bucky! You could have 220,000 trucks, cars, and vans out there! The USPS maintains the nation's largest civilian fleet with nearly 220,000 vehicles to support 37,000 Post Offices staffed by more than 785,000 employees who annually collect, process and deliver nearly half the world's mail volume -- 212 billion pieces -- to 148 million addresses six days a week. Of that 220,000, 195,000 are vehicles often seen in neighborhoods delivering mail. And 43,000 are already alternative fuel capable. Did you know? The USPS began testing alternative fuel vehicles beginning in 1899 with battery power. A one-cent increase in a gallon of fuel annually adds $8 million to USPS expenses. Fuel costs last year were $1.7 billion. This year's will increase by $600 million.
