Drive down your gas costs this Memorial Day weekend

Did you know that your GPS device and certain smartphone apps can give you real-time gas mileage tips, and point you to the cheapest nearby gas station? How about the fact that every extra pound of luggage decreases your fuel economy, as does driving faster than 60 miles per hour? Learn these gas-saving secrets and more from this video, as well as six other videos on fuel efficiency from the Alliance to Save Energy.

Here are a few more tips:

  • Avoid aggressive driving. Speeding, rapid acceleration and rapid braking can lower gas mileage by 33% at highway speeds and by 5% around town, according to the Alliance to Save Energy.
  • Avoid excessive idling. Idling can waste a quarter to a half gallon of fuel per hour, depending on engine size and air conditioner use. But it only takes a few seconds’ worth of fuel to restart your engine, according to the U.S. Department of Energy.
  • Combine errands into one trip. Several short trips taken from a cold start can use twice as much fuel as a multipurpose trip covering the same distance when the engine is warm.
  • Beat the traffic. When possible, drive during off-peak hours to avoid stop-and-go or bumper-to-bumper traffic conditions, thereby reducing gas costs, time and stress.
  • Keep tires inflated. Properly inflated tires can improve mileage by up to 3.3%. Conversely, under-inflated tires can lower gas mileage by 0.3% for every 1 psi drop in pressure in all four tires. In addition, proper inflation improves tire longevity and driving safety. Find the proper tire pressure for your vehicle on a sticker on the driver’s side door jamb, in the glove box, and/or in your owner’s manual.

This chart shows how much you can save from each fuel efficiency tip. These suggestions can also improve your driving, increase the life of your tires, and help you beat traffic.

FUEL EFFICIENCY TIPS

MPG INCREASE ANNUAL SAVINGS
Smart Driving
Avoid aggressive driving up to 33% $981
Drive safe (highway) up to 10% $218
Lose 100 pounds from trunk up to 2% $40
Car Maintenance
Tune up vehicle up to 4% $82
Fix oxygen sensor up to 40% $1,308
Keep tires inflated up to 3% $61
Use recommended oil up to 2% $40
Fuel Efficient Car Switching from
20 MPG to 30
MPG vehicle
$930 in fuel costs*
The MPG increases and dollar savings are estimated for each tip based on data from 2011 Transportation Energy Data Book and U.S. Energy Information Administration (EIA) assuming vehicle fuel economy as 21.2MPG, average national gas price as $3.69/gallon, and annual 11,300 miles of travel. Actual results depend on how well you already follow these practices, whether you use more than one tip at a time, and other factors.

Expanding solar power in Massachusetts

Solar power is one of several steps we’re taking toward our big goal of being supplied 100 percent by renewable energy. Earlier this year, we had 115 rooftop solar installations in seven countries. And yesterday, the Boston Globe reported that Walmart will install solar panels on top of 27 Massachusetts stores. That’s enough to power 2,600 homes, according to the story, which you can read here.

Burning energy for the better

Before there were smart cars, there were bicycles. And aside from walking, riding a bike is still one of the most energy-efficient ways to get anywhere.

With summer approaching, now is the perfect time to hop on a different set of wheels. Not only is May National Bike Month, but May 18 is Bike to Work Day. Today, Walmart started a bike sharing program at its corporate headquarters, providing 80 bicycles for associates to check out for free during their time at the office.

In addition to its environmental benefits, bicycling is a fun way to get active. Here’s a look at a few more facts.

Building a renewable energy strategy, one block at a time

Marty Gilbert

Marty Gilbert walks along an installation of ground-based solar panels.

When I’m not working, I enjoy spending time with my family.  The schedule at our house revolves around our two boys – Jake, 14, and Harrison, 10.  In the last three years, as I’ve gotten more deeply involved in helping Walmart find ways to use renewable energy, I’ve been more aware of how what I do at work can help contribute to a better world for Jake and Harrison for years to come.  Continue reading
