Eight Reasons We’re Using Less Oil

Uncle Sam’s Tougher Fuel Economy Rules

By the 2016 model year, automakers will have to achieve average fuel economy for their passenger cars and light trucks of 34.1 miles per gallon, up from 27.3 mpg in the 2011 model year. The rule change means auto companies will have to improve their models’ fuel efficiency by 4.3% each year between now and 2016.

Washington isn’t stopping there -- regulators are working on even stricter rules for model years 2017 through 2025, with final targets expected to range from 47 to 62 mpg for cars and light trucks. These conservation moves spell a huge reduction in oil use.

Electric Cars: Who Needs Gasoline?

Battery power promises to take fuel efficiency to the max, as automakers expand their offerings of conventional hybrid cars and roll out models that can run purely on electricity. The 50-mpg Toyota Prius, the most recognizable hybrid on the road, faces increasing competition from Honda, Ford, Hyundai and other manufacturers making their own hybrids.

Meanwhile, Nissan’s all-electric Leaf and Chevy’s plug-in hybrid Volt run on electrons and never or seldom need gas. Look for more manufacturers to join the electric-car rollout in the next few years, particularly as battery costs decline.

Guzzlers Out, Gas Sippers In

In response to rising consumer demand, automakers are designing downsized engines that keep horsepower up while cutting fuel consumption. How? They're using turbochargers, direct fuel injection and advanced transmissions with more gears. Result: Ford, Hyundai, Chevrolet and Honda have all recently introduced conventional gas-powered cars that achieve at least 40 mpg on EPA’s highway test cycle. These cars include models of Ford’s Fiesta and Focus, Chevrolet’s Cruze, Honda’s Civic and the Hyundai Elantra.

Until a year ago, the only gas-powered, nonhybrid car in the U.S. that could manage that trick was Daimler’s smart fortwo, a tiny two-seater. Meanwhile, lots of older gas guzzlers were retired as part of Uncle Sam’s recent cash-for-clunkers program.

We're Logging Fewer Miles on the Road

The number of miles driven by U.S. drivers grew every year from 1991 until 2005. But the trend reversed in 2006, as the number of miles driven dropped slightly from 2005’s 1.7 trillion.

The trend continued into 2007 and accelerated dramatically in 2008 -- down to just over 1.6 million -- when expensive oil pushed gas prices over $4 per gallon. The consensus among analysts is that the trend will continue. As the age-old axiom puts it: The cure for high prices is...high prices.

The Miracle of GPS

The rapid spread and widespread use of global positioning systems for finding the fastest, least-congested routes to work and other destinations is making travel more efficient. Truckers are leading the way. The price of diesel fuel is their biggest cost, and with diesel fuel now more costly than gasoline, trucking firms are doing all they can to wring more miles out of each gallon. GPS is playing a big role, helping drivers drive smarter and conserve fuel.

Meanwhile, railroads -- also a user of diesel fuel -- are switching to lighter rail cars, more-efficient locomotives and friction-reducing rails to cut their consumption.

Smarter Toll Collection

More than half of all states now employ some form of electronic toll collection, which allows drivers to pay road tolls without having to stop and fumble for change to hand an attendant while wasting fuel and, in turn, causing fuel-wasting backups.

E-ZPass and other such electronic systems will grow more prevalent as cash-strapped states look for ways to cut toll collecting expenses, including salaries for toll collectors. It’s a small change that can save millions of gallons of fuel each year.

Switching to Natural Gas

Abundant supplies of natural gas in the U.S. spell a viable and growing alternative to oil. Today, there are about 110,000 vehicles running on natural gas in the U.S. Most are in light-duty commercial roles -- city buses, for example.

But vehicle use of natural gas is poised to soar in coming years as new fields are tapped, driving the price of natural gas to rock bottom. It’s cheap, too -- engines burning compressed natural gas cost less to operate than oil-powered models. Truckers are eying a switch to liquefied natural gas that produces the same power as big diesel engines at about $1.50 less per gallon.

Filling Up with Corn (and Garbage)

Ethanol distilled from corn has already displaced about 10% of U.S. oil demand. That’s sure to go up, courtesy of the Environmental Protection Agency’s thumbs-up to a 50% increase in the amount of ethanol that refiners can blend into regular gasoline. Also helping the cause: Growing acceptance and use of E85 -- 85% ethanol and 15% gas -- in vehicles equipped with "flex fuel" engines.

Though cars running on E85 get fewer miles per fill-up, the cost of a gallon of E85 is now about 50¢ cheaper than a gallon of gasoline. That’s getting people’s attention. Biofuels will make even greater inroads as production expands from grains to nonfood materials such as algae, switchgrass and, yes, even household trash that’s now thrown into landfills.
