Fuel Economy
In 2004 UPS announced that it would save fuel by minimizing left turns. Because drivers are idle at intersections while waiting to make left turns, UPS developed software that routes the day's packages with preference to right turns. Since UPS operates a fleet of over 100,000 ground vehicles, the fuel savings are considerable. In 2005, UPS eliminated 464,000 miles (747,000 km) from its travel and saved 51,000 US gallons (190,000 l) of fuel.

Famous quotes containing the words fuel and/or economy:
“The particular source of frustration of women observing their own self-study and measuring their worth as women by the distance they kept from men necessitated that a distance be kept, and so what vindicated them also poured fuel on the furnace of their rage. One delight presumed another dissatisfaction, but their hatefulness confessed to their own lack of power to please. They hated men because they needed husbands, and they loathed the men they chased away for going.”
—Alexander Theroux (b. 1940)
“War. Fighting. Men ... every man in the whole realm is in the army.... Every man in uniform ... An economy entirely geared to war ... but there is not much war ... hardly any fighting ... yet every man a soldier from birth till death ... Men ... all men for fighting ... but no war, no wars to fight ... what is it, what does it mean?””
—Doris Lessing (b. 1919)
