PepsiCo Inc is testing greener vending machines, a move that helps the soft drink maker reduce its environmental footprint and gives businesses a little relief on their electric bills.
The test involving 30 machines in the Washington, D.C., area has just begun. Pepsi hopes to begin rolling them out worldwide over the next several years, said Robert Lewis, vice president of packaging and equipment development.
The new machines use 5.08 kilowatt-hours of energy per day, down about 15 percent from a nationwide average of 6 kilowatt-hours used by current machines. Current machines already use 44 percent less energy on average than the machines used six years ago.
"That was the equivalent of burning five 100-watt bulbs constantly," Lewis said, referring to the 2003-era machines. "We're currently down to about two 100-watt bulbs. They're not using a lot of energy as it is."

The new machines also emit about 12 percent less greenhouse gas, in part by keeping the drinks cool with carbon dioxide instead of the usual hydrofluorocarbons (HFCs), which scientists say contribute to global warming.
