What makes up the price of Gasoline?

Consider the game of chicken that plays out every day across Pennsylvania Highway 441. In Marietta, where the road hugs the Susquehanna River, a Rutter's Farm Store gas station stands on one side, a Sheetz gas station on the other.

Kelly Bosley, who manages Rutter's, doesn't even have to look across the highway to know when Sheetz changes its price for a gallon of gas. When Sheetz raises prices, her own pumps are busy. When Sheetz lowers prices, she has not a car in sight.

She calls Rutter's headquarters to report the competition's new price and wait for instructions.

"I call a lot of times and say, 'They went down, hurry up! Hurry up! Call me! Call me!' Or it could be where theirs goes up, and I'll say, 'Take your time! You know, I like being busy.' But I have no control over that."

You think you feel helpless at the pump?

Bosley makes a living selling gas -- and even she has little control over what it costs.

So how exactly are gas prices set? What determines the hair-pulling figure you see displayed in large electronic or plastic numbers? Why is a gallon of gas, say, $4.11 -- not $4.10 or $4.12? Why is the price different across the street?

It all starts with oil.

The biggest factor in the skyrocketing price of gasoline is the historic ascent of crude oil, which has surged from $45 per barrel in 2004 to more than $135 last week, setting new record highs all the while.

In the first quarter of this year, based on a retail price of gas that now seems like a steal -- $3.11 a gallon -- crude oil accounted for all but about a dollar, or 70 percent, of the cost, according to the federal government.

The rest is a complex mix of factors, from the cost of turning oil into gas to taxes to marketing costs to, sometimes, nothing more than the competitive whims of gas station owners.

Not that understanding the breakdown makes it any less cringe-inducing to fill 'er up.

Step by step

First a primer on how gas gets to your tank:

Once oil is pumped from the ground, it can be sold on the spot market, a last-minute trading arena where oil companies and distributors buy and sell to each other, or straight to refiners. After it's brewed into gasoline, the product can again be sold on the spot market, or directly to wholesalers, who in turn can supply their own stations or sell it to other retailers.

Each step of the way, buyers and sellers negotiate a price.

At the starting point of all this is the price of oil -- which, like the oil itself, is nothing if not crude.

The knee-jerk villains are the oil companies, fat with multibillion-dollar profits, frequent targets of populist anger. But wait: The oil companies don't set the price of oil or the cost of gas.

Prices are a function of the open market, the result of futures contracts traded on the New York Mercantile Exchange and other exchanges around the world.

Buying the current July crude oil futures contract means you're buying oil that will be delivered by the end of July. But most investors who trade futures have no intention of ever accepting the underlying oil: Like stock investors who frequently buy and sell their holdings, they're simply betting prices will rise or fall.

Lately, oil futures have been rising.

Why? Blame the falling dollar. Oil is priced in U.S. dollars, and the weaker the dollar gets, the more attractive dollar-denominated oil contracts are to foreign investors.

The rush of buyers keeps pushing oil futures to a series of new records, and the rest of the energy complex, including gasoline futures, has followed. That pushes up the price of gas that goes into your tank.

"Crude is the driver," said Jim Ritterbusch, president of energy consultancy Ritterbusch and Associates in Galena, Ill. "As long as it stays up there, gasoline's not going to be able to decline much at all, even if demand slips. That's just the way it is."

There is some evidence Americans are buying less gas as the price marches higher, and common sense suggests they would cut back even more if gas rose to $4.50 or $5 a gallon.

Lower demand should mean lower prices -- but it takes time for that to happen, given the enormous scale of refining operations that produce gasoline.

"Once demand begins to slow, that needs to translate into inventories, then you get some price weakening," Ritterbusch said. "But it takes a while."

Oil and gasoline prices often move in the same direction, but they aren't linked directly. In fact, while oil prices have more than doubled in the past year, gasoline is only up about 19 percent during the same time.

Oil prices often fluctuate with production decisions from the Organization of Petroleum Exporting Countries, which supplies about 40 percent of the world's crude, or when conflict in the Middle East or Nigeria threatens supplies.

As for gasoline prices: They're closely tied to demand from U.S. drivers and how efficiently refineries are operating. Falling production or inventories often send prices skyrocketing.

Those prices can vary greatly depending on the region.

The Gulf Coast is the source of about half the gasoline produced in the United States, and areas farthest from there tend to have higher prices because of the cost of shipping gas via pipeline and tanker truck all over the country.

Beyond oil

It's not only about the price of oil. Other costs are a factor -- though they've remained relatively stable.

For example, federal and state taxes added 40 cents to a gallon of gas in the first three months of this year, roughly the same amount as they added four years ago.

California's 63.9 cents of tax is the nation's highest, Alaska's 26.4 cents the lowest. (Iowa's is 40.1 cents; Illinois, 57.9; and Missouri, 36.0 cents per gallon.) How the money is used varies from state to state, though the federal take helps to build and maintain highways and bridges.

Marketing and distribution costs -- the tab for delivering gasoline from refiner to retailer -- were 27 cents to start the year, only 6 cents above the cost four years ago.

The cost of refining added 27 cents to a gallon in the first quarter of this year, a nickel less than what it added in 2004, according to the Energy Information Administration.

That refining occurs at sprawling industrial complexes across the United States, with most of the biggest along the Gulf Coast. Barrels of crude arrive each day by pipeline, ship and barge. The refineries, by heating, treating and blending the raw oil, turn out products like diesel and lubricating oil.

And, of course, gasoline.

Maintaining a balance

What happens when that gasoline makes its way to your neighborhood gas station?

Major oil companies own fewer than 5 percent of gas stations. Most are owned by small retailers -- and many of them say they're struggling these days to turn a profit on gas. That's because wholesale gasoline prices have risen sharply in recent months -- again, blame it on crude -- but station owners have been unable to raise pump prices fast enough to keep pace.

And you can't keep jacking up the price when drivers are buying less.

Gas station owners face a balancing act: They must try to maintain a price that allows them to afford the next shipment of gasoline but not give the competition an edge.

Stations pay tens of thousands of dollars for each gas shipment before they see a cent in the register. Eventually, many make only a few cents on a gallon of gasoline, a margin that can disappear altogether when credit card fees are added in.

Thank goodness for beef jerky and sodas.

Most gasoline retailers long ago got past any illusion they can make money selling gas. They rely on gas sales to drive traffic to their shops, where they hope auto repairs or food and drink sales will help them turn a profit.

"You're always out there competing with the guy next door -- literally with the guy across the street -- and worried too about how you're going to pay for your next supply," said Rayola Dougher, a senior economic adviser at the American Petroleum Institute, the oil industry's trade association.

In the Philadelphia suburb of Havertown, Pa., earlier in the week, Sunoco station operator Steve Kehler received a load of gasoline -- 9,000 gallons -- which, at a wholesale price of $3.729 a gallon, cost him 4 cents more than the previous load.

That left him in a sticky situation: Should he raise prices right away to recoup some of his higher gasoline expenses, or should he hold off for a couple of days in hopes his competitors also will have to raise their prices?

"I'm surrounded by $3.89's, and I'm already at $3.91," said Kehler, referring to his prices and those of some nearby competitors. "I'm going to play a little waiting game right now."

The $33,600 Kehler must pay for his overnight gasoline delivery won't be debited from his bank account for a few days. That gives him a little breathing room, time to hold prices steady. Hiking prices too quickly will hurt sales.

"I'll probably change it tomorrow night, at closing," Kehler said. "I'll go up 4 cents."

That will put Kehler at a gross margin of about 20 cents a gallon. After paying credit card fees, labor and rent, Kehler will be lucky to break even on his gasoline sales.

Of course, the plight of retailers is little consolation for drivers.

Mayra Perez said she works two jobs to help support her family, and gasoline is becoming harder to afford.

She was filling the tank of her car in Miami last week to the tune of $3.89 per gallon.

"This is horrible," she said. "On the weekend, my husband and I use only one car to save on gas.

"But then there's the cost of food, milk, eggs, the rent."

As William K. Whiteford quotes “Smell that! That's gasoline you smell in there. You can't buy any perfume in the world that smells as sweet.”

General Gyan

More & more stores are encouraged to use bags made of recyclable paper, cutting down on plastic bags. Customers are also encouraged to get their own bag.

Facts:
  • Plastic bags cost about a paisa 50 each, paper costs about a Rs.2 and compostable bags can run as high as Rs.10 each.
  • The bags also must be segregated from regular plastic, making recycling efforts more difficult.

Meanwhile:

  • Paper bags generate 70 percent more air pollutants and 50 times more water pollutants than plastic bags, according to the Environmental Agencies.
  • This is because four times as much energy is required to produce paper bags and 85 times as much energy is needed to recycle them.
  • Paper takes up nine times as much space in landfills and doesn't break down there at a substantially faster rate than plastic does.

Public education campaigns about littering and recycling can help more than ineffective bans on products that are used every day by billions of people worldwide.

Concentrating solar power

Read an interesting article on Concentrated Solar Power & this technology has been overshadowed by photovoltaic solar energy.

A brief on Concentrating solar power
Concentrated sunlight has been used to perform useful tasks since the time of ancient China. A legend claims Archimedes used polished shields to concentrate sunlight on the invading Roman fleet and repel them from Syracuse. In 1866, Auguste Mouchout used a parabolic trough to produce steam for the first solar steam engine, and subsequent developments led to the use of concentrating solar-powered devices for irrigation, refrigeration and locomotion.

Concentrating Solar Power (CSP) systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. The concentrated light is then used as a heat source for a conventional power plant. A wide range of concentrating technologies exist; the most developed are the solar trough, parabolic dish and solar power tower. These methods vary in the way they track the Sun and focus light. In all these systems a working fluid is heated by the concentrated sunlight, and is then used for power generation or energy storage.

The SEGS plants in California and Acciona's Nevada Solar One near Boulder City, Nevada are representatives of this technology.

A parabolic dish system consists of a stand-alone parabolic reflector that concentrates light onto a receiver positioned at the reflector's focal point. The reflector tracks the Sun along two axes. Parabolic dish systems give the highest efficiency among CSP technologies. The Big Dish in Canberra, Australia is an example of this technology.

A solar power tower uses an array of tracking reflectors (heliostats) to concentrate light on a central receiver atop a tower. Power towers are less advanced than trough systems but offer higher efficiency and better energy storage capability. The Solar Two in Daggett, California and the Planta Solar 10 in Sanlucar la Mayor, Spain are representatives of this technology.

Nanosolar - The Sun power at your Doorstep

Sun always has been the most energy provider source for Earth & Nanosolar is tapping the right source. Nanosolar is a developer of solar power technology. Based in Palo Alto, CA, Nanosolar is developing and commercializing an extremely low cost printable solar cell manufacturing process. Nanosolar coatings are as thin as a layer of paint and can transfer sunlight into power quite efficiently.

Nanosolar was started in 2001 by Martin Roscheisen and Brian Sager, who met through their friend Reid Gershbein, and is headquartered in Palo Alto, California. The company has received financing from a number of technology investors including Benchmark Capital, MDV, and Larry Page and Sergey Brin, the founders of Google. Nanosolar received the largest amount in a round of Venture Capital technology funding, amongst United States companies during Q2 2006, with 100 million USD of new funding secured.

Solar powered buildings and homes might just become standard in the future, thanks to this innovative technology by Nanosolar Inc. Nanosolar has developed proprietary process technology that makes it possible to produce 100x thinner solar cells 100x faster. The underlying technology for these solar cells is nothing new, having been around for decades, but Nanosolar has created the actual technology to manufacture and mass produce the solar sheets. The solar cells are produced by a solar printing press of sorts rolling out these aptly named PowerSheets rapidly and cheaply. The machines apply a layer of solar-absorbing nano-ink onto metal sheets as thin as aluminum foil reducing production costs to a mere tenth of current solar panels and at a rate of several hundred feet per minute. The first commercial cells for consumer use are scheduled to be released this year.

These solar cells successfully blend the needs for efficiency, low cost, and longevity and will be easy to install due to their flexibility and light weight. In order to compete with the energy produced from coal solar has been in need of finding a way to shrink its costs down from $3 per watt to $1 per watt. Nanosolar's cells use absolutely no silicon as is the standard for current solar production and the efficiency of the PowerSheet cells are competitive with the traditional systems as well. The golden kicker, the cost to produce these solar coatings is a mere 30 cents per watt!!

Nanosolar has built what is soon to be the largest solar plant in world in San Jose and once full production begins early next year the facility is capable of producing a whopping 430 megawatts per year, more than the combined total of every other solar manufacturer in the U.S. The biggest problem for Nanosolar is keeping up with the impending solar boom. California recently launched the Million Solar Roofs initiative providing tax breaks and rebates to encourage the installation of $100,000 solar roofs per year for a solid decade. Thanks to the innovative approach Nanosolar is poised to launch the solar revolution and we the consumer stand to benefit greatly as the result.
