Gasoline is so yesterday

At the Postal Service, the future is now. USPS has already delivered more than 1 million pieces of mail using vehicles that eliminate pollution and don’t use gasoline.

During a three-year evaluation period, some letter carri­ers in Fort Belvoir and Springfield, VA, and Irvine, CA, began delivering their routes using fuel-cell vans developed by General Motors. The vehicle’s fuel cell combines stored hydrogen with oxygen from the air to produce the electric­ity that powers the car. The only output — pure water.

Last summer, General Motors introduced the Chevrolet Equinox, its next-generation fuel-cell vehicle. The Postal Service will again partner with General Motors to test and evaluate the Equinox.
