As the operator of the largest civilian fleet of vehicles in the country, the United States Postal Service (USPS) could save money by gradually substituting its gas-powered vehicles with hybrid (gas/electric) and/or electric-only vehicles. For residential deliveries, for instance, hybrids would run on electricity alone during delivery stops, and quick runs from one residence to another. Some of the benefits from this investment:
* Reduced fuel costs (benefits the Agency);
* Shipping costs do not need to increase with frequency (benefits consumers);
* Less pollution in the environment (benefits local residents);
* Increased production of domestic vehicles demanding additional workforce (benefits Detroit, parts manufacturers, the unemployed & the economy in general).
