Air

The USPS has the nation's largest fleet of alternative-fuel vehicles. Instead of gasoline, they run on electric batteries, compressed natural gas, ethanol, and biodiesel fuel. All these vehicles produce less pollution than regular vehicles. The electric vehicles produce no pollution at all, and are clean, quiet and efficient to run. Using alternative-fuel vehicles shows our commitment to sustainable principles - and helps preserve our environment from harmful gasoline emissions.

Interesting Fact

The USPS tested the first electric mail vehicle in Buffalo in 1899 as an alternative to the horse and buggy. This was just a few years after Henry Ford tested his first car!

Lighting for homes

The USPS generates 30 million kilowatt hours of electricity annually by using less of Earth's non-renewable resources and more renewable energy sources. This is enough to light 300,000 homes for a year, and stops several pollutants being released into the atmosphere each year:

• 25 million pounds of carbon dioxide,
  
• 60 thousand pounds of nitrogen oxides,
  
• 18 thousand pounds of sulfur dioxide.
