EH2ED Day 16: Plant a row for the Hungry!

Backyard gardeners, plant an extra row in your and donate the extra harvest to a soup kitchen, food or hunger relief agency. Visit www.GroGood.com to take a pledge, obtain tips and techniques on how to grow an edible garden, and find information on local food agencies that accept fresh produce donations.

EH2ED Day 15: Pay Your Bills Online!

Eliminating your paper trail by banking and paying bills online does more than save trees. It also helps reduce fuel consumption by the trucks and planes that transport paper checks. If every U.S. home viewed and paid its bills online, the switch would cut solid waste by 1.6 billion tons a year and curb greenhouse-gas emissions by 2.1 million tons a year.

EH2ED Day 14: Get Out of Hot Water

Turn your hot water heater down by just ten degrees and knock off three to five percent from your power bill.

Make a Pet-Safe Carpet Deodorizer

Having a pet increases the odors in your home, especially on the carpets and upholstery they spend all day lounging on. While strongly scented carpet powders can most certainly help you get the smells outs, most store bought powers have all sorts of compounds in them you may not want your pets sniffing up. Fortunately over at the home design blog Re-Nest, they've shared a simple and pet-friendly alternative to store bought powders:

Baking soda is an ever-popular deodorizer and it's pet-safe. Crush up a handful of dry lavender and mix with a cup of baking soda, and sprinkle that over your carpet. If you'd like to use essential oils, mix a few drops of your favorite(s) in with baking soda (not enough to make it wet), and then break up any clumps and sprinkle that over your carpet.

Let it sit for a bit, vacuum it up, and you've got fresher and fido-friendly carpets. If you have your own pet-friendly cleaning tips, share them in the comments below.

PepsiCo Tests Green Vending Machines

NEW YORK (Reuters) - 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.

The green machines, which have won the praise of Greenpeace, are the latest step PepsiCo is taking to promote its more environmentally friendly ways. Both PepsiCo and Coca-Cola Co have come under fire for issues such as using too much plastic, and have made changes such as making lighter bottles and conserving more water.

CUTTING COSTS

The new machines are more expensive than current equipment, Lewis said, but declined to say by how much.

PepsiCo, whose brands include Pepsi, Mountain Dew, Sierra Mist and Aquafina, currently has about 4 million to 5 million vending machines and coolers around the world.

Vending machines are typically owned and serviced by the company's bottlers, which share their revenue with the offices, schools and stores that house them. Therefore, those customers will not incur any charges for the new machines, yet will benefit from lower energy bills, Lewis said.

PepsiCo worked with Greenpeace Solutions, an arm of the large environmental organization, to develop the program.

Greenpeace Solutions Director Amy Larkin said PepsiCo was leading the way to improve a technology that people use every day but rarely think about.

"They're transforming the industry in a way that is going to be more climate-friendly to a great degree, so what can I do but applaud that," Larkin said.

While Pepsi's greener vending machines are the first in the United States, Unilever Plc's Ben & Jerry's ice-cream brand introduced coolers that use carbon dioxide, she noted.

Coca-Cola has introduced HFC-free vending machines in Britain, and used them at official venues at last year's Beijing Olympics.
