The post office will no longer deliver letters on Saturdays. The move comes as the United States Postal Service struggles with shrinking mail volume and rising operating costs.
The Postal Service owns and operates the world's largest civilian vehicle fleet with more than 213,000 cars, trucks, and vans that travel 1.2 billion miles each year. In fiscal year 2010, USPS vehicles consumed about 146 million gasoline gallon equivalents (GGE), or about 700 GGE if you include contract vehicles. The cost of fueling and maintaining USPS vehicles runs about $1 billion a year.
