Natural Gas Dethrones King Coal As Power Companies Look To Future
American Electric Power's natural gas-burning plant in Dresden, Ohio, is one of the energy company's new investments in alternatives to coal-burning plants.
Michael Williamson/The Washington Post/Getty ImagesThe way Americans get their electricity is changing. Coal is in decline. Natural gas is bursting out of the ground in record amounts. And the use of wind and solar energy is growing fast. All this is happening as power companies are trying to choose which kind of energy to bet on for the next several decades.
Until recently, half of these plants burned coal to make electricity. Now, that's down to about one-third. Since 2010, about 150 coal plants either have been retired or it's been announced they will be retired soon.
What knocked King Coal off its throne? Mostly natural gas. "We added almost twice as much natural gas capacity as we retired coal capacity last year," says Trevor Houser, an energy analyst with the Rhodium Group in New York. Why gas? "That is primarily because of the price."
The price of natural gas is well below what it was a few years ago. That's mostly because hydraulic fracturing technology is reaching more gas reserves, and also because a weak economy has lowered the demand for electricity. And there's plenty more gas to come. On Thursday, a study from the University of Texas confirmed government estimates of huge reserves in Texas alone.
That would suggest that coal is doomed.
But not so fast. The gas market is quirky. As people started burning more natural gas, gas prices crept up. It's classic economics: "As natural gas prices have started to increase over the past few months," Houser points out, "coal's share of U.S. power generation has increased right alongside it."
So this is the brave new energy world of the 21st century ? two evenly matched opponents. Natural gas is providing 30 percent of our electricity, with coal a half-dozen percentage points above that, trying to halt its downward spiral. Add in electricity powered by water, wind and solar ? which, collectively, have surged to now provide about 12 percent of our power ? and you've got heated competition for access to your wall socket.
The future of electric power is at stake. Coal plants are closing. Nuclear power is not growing. The economy is picking up. That means more demand for electricity.
"In the last five years or so, there's been an increasing degree of concern in the industry that we need to start building new capacity," says Revis James, who analyzes the market for the utility industry's Electric Power Research Institute.
New capacity ? new power plants ? will determine the kind of energy Americans use for the next 50 years or so. Natural gas would seem the economical choice. But here's the rub: The actual cost of the gas ? rather than the cost of building the equipment to burn it ? accounts for about half a utility's operating cost. That's way more than coal or uranium fuel. So when gas prices fluctuate (and they're famous for doing that) it can wreck a utility's bottom line. "The real $64,000 question," James says, is, 'What will happen to gas prices as the power sector's consumption of gas starts to significantly increase?' "
And once you build those gas-fired plants, you're stuck with them for decades. You have to pay back the cost of building the plant. James says that's why power companies are nervous about jumping on the gas bandwagon when gas prices are so volatile.
Bruce Nilles is hoping they don't jump on that wagon. Nilles is a lawyer with the Sierra Club, which has spent the past decade fighting permits for new coal plants.
Nilles agrees that using more natural gas has reduced the country's climate-warming carbon emissions. But, he says, don't build any more. That could divert the country away from the cleanest energy ? wind, solar and geothermal power. "What we're trying to avoid," Nilles says, "is building hundreds of new gas plants, locking us in for the next 20, 30 years, and thereby making it impossible to make a swift transition to clean energy."
Nilles says it's a race ? coal is slowing down, renewable forms of energy are closing the gap, and natural gas is a dark horse coming up on the outside.

CAPE CANAVERAL, Fla. (AP) ? A commercial craft carrying a ton of supplies for the International Space Station ran into thruster trouble shortly after liftoff Friday. Flight controllers managed to gain control, but were forced to delay its arrival at the orbiting lab.
The earliest the Dragon capsule could show up is Sunday, a full day late, said top officials for NASA and the private company SpaceX.
"We're definitely not going to rush it," said SpaceX's billionaire founder Elon Musk. "We want to make sure first and foremost that things are safe before proceeding."
The Dragon, owned and operated by SpaceX, holds considerable science experiments for the International Space Station as well as food and spare parts.
Musk said six hours into the flight that all four sets of thrusters finally were working properly. "All systems green," he reported via Twitter. The problem might have been caused by a stuck valve or line blockage. The thrusters are small rockets used for maneuvering the capsule.
It is the first serious trouble to strike a Dragon in orbit. None of the three previous flights had any signs of thruster issues, Musk told reporters by phone from company headquarters in Hawthorne, Calif.
He said it appeared to be a glitch versus a major concern.
NASA space station program manager Mike Suffredini said at least three groups of thrusters on the Dragon need to work before the capsule can come close to the complex. That's a safety rule that will not be waived, Suffredini said.
Engineers for both SpaceX and NASA plan an exhaustive study before allowing the rendezvous to take place. The Dragon could hang around at least a month before linking up with the station, Musk said. It's supposed to spend more than three weeks there.
A crucial maneuver needed to be made quickly, however, to raise the orbit and keep the capsule from plunging down through the atmosphere. Musk promised in a tweet that was forthcoming.
SpaceX has a $1.6 billion contract with NASA to make a dozen deliveries to restock the space station. This is the third trip by a Dragon capsule to the station; the first Dragon flight, in 2010, was a solo test.
Musk acknowledged it was scary for a while.
"Yes, absolutely, it was a little frightening there," he told reporters.
He stressed that the company's Falcon 9 rocket performed "really well" and that the thruster problem was isolated to the Dragon.
On the previous flight in October, one of nine first-stage engines on the Falcon shut down too soon. A communication satellite hitching a ride was lost.

Cancer doesn't change young girls' desire to have children, study shows
Mar. 1, 2013 ? Researchers at Moffitt Cancer Center and colleagues have found that healthy adolescent females have predetermined expectations for becoming parents in the future, but have concerns about fertility and childbearing should they develop a life-threatening illness, such as cancer.
The study appeared in the February issue of the Journal of Adolescent Health.
According to the researchers, this study helped further validate a tool that seeks to understand teenage girls' hopes and feelings about reproduction, especially when fertility is threatened by cancer. The participants were given the same survey tool previously used to determine the values and hopes of female adolescents who had cancer diagnoses. The researchers included healthy controls to compare their responses to those of teens who have been diagnosed with cancer and whose fertility may be at risk.
"This study sought to examine if girls who did not have cancer wanted to have children in the future and determine if they would feel negatively about losing the ability to have a biological child due to a life-threatening illness, such as cancer," said study lead author Gwendolyn P. Quinn, Ph.D., member of the Health Outcomes and Behavior Program at Moffitt. "We found that teen girls with cancer had the same hopes and dreams for the future as their healthy peers."
The researchers suggested that their data could demonstrate to health care professionals that the desire to have children does not change with a cancer diagnosis and could serve to "motivate health professionals to discuss fertility and preservation options with more of their teen patients in the future," issues rarely discussed among the age groups tested.
Control group participants included 25 female adolescents ages 12 to 18. They were divided into two age groups: 12 to 14, and 15 to 18. A 10-statement survey was designed to elicit responses about if a participant would feel sad, disappointed or frustrated if facing fertility impairment. Participants were also allowed to write about their feelings. Each provided feedback on the research tool, commenting on the types of statements and wording of questions.
The researchers found differences between the older and younger group responses to a few of the survey statements. For example, the older participants felt that they should have more opportunity to express their feelings rather than agree or disagree with predetermined ideas.
"The reproductive concerns of healthy female adolescents parallel those of adolescents with cancer in the same age ranges," explained Quinn. "Because this study highlights the fertility concerns among healthy adolescents, it strengthens the argument for using the adapted 10-item scale to assess girls with cancer."
The scale, researchers said, can be used in the clinic to determine the values female adolescents with cancer hold regarding fertility and how the life-altering event of cancer has impacted these values.
"Understanding the importance of reproductive concerns of adolescents confirms the need for interventions and developmentally appropriate tools to prevent negative quality- of-life effects during survivorship among those diagnosed with cancer," the researchers concluded. "The validation of this tool with a healthy population increases its potential value for use with girls diagnosed with cancer."

Pessimists May Live Longer
Low expectations for a happy future might actually propel you into old age.
Compared with their counterparts with a sunnier outlook, older Germans who are more pessimistic tend to live longer, healthier lives, a group of researchers found.
"Our findings revealed that being overly optimistic in predicting a better future was associated with a greater risk of disability and death within the following decade," researcher Frieder R. Lang, of the University of Erlangen-Nuremberg in Germany, said in a statement. "Pessimism about the future may encourage people to live more carefully, taking health and safety precautions."
Lang's team looked at the 1993 to 2003 results of an annual German survey of tens of thousands of people, ages 18 to 96. These polls included information about the participants' health as well as their ratings of how satisfied they were with their lives and how satisfied they thought they would be in five years, on a scale of 0 to 10.
Among those 65 and older, 43 percent of the respondents had underestimated what their future life satisfaction would be five years after the initial survey, the researchers said. Thirty-two percent overestimated it and 25 percent had predicted accurately.
Each notch of overestimation was linked to a 9.5 percent increase in the chance a respondent would report a disability and a 10 percent increase in the chance the person would be dead five years later.
"Unexpectedly, we also found that stable and good health and income were associated with expecting a greater decline compared with those in poor health or with low incomes," Lang said. "Moreover, we found that higher income was related to a greater risk of disability."
Other contradictory studies suggest that the jury's still out on the secret to longevity and successful aging. Last year, a survey of about 1,000 older Americans found that a resilient attitude might trump good physical health in people's perception of how successfully they are aging. Another 2012 study of centenarians found that personality traits like being outgoing, optimistic and easygoing, as well as enjoying laughter and staying engaged in activities may be an important part of the longevity mix, possibly tied to genes.
The new findings were detailed online in the journal Psychology and Aging.

Cancer risks higher in worst hit Fukushima area: WHO
GENEVA (Reuters) - People in the area worst affected by the Fukushima Daiichi nuclear accident two years ago have a higher risk of developing certain cancers, the World Health Organisation said on Thursday.
A 9.0 magnitude earthquake and tsunami on March 11, 2011, killed nearly 19,000 people and devastated the Fukushima Daiichi nuclear plant, triggering meltdowns, spewing radiation and forcing about 160,000 people to flee their homes.
"A breakdown of data, based on age, gender and proximity to the plant, does show a higher cancer risk for those located in the most contaminated parts," Dr. Maria Neira, WHO director for public health and environment, said in a statement.
In the most contaminated area, the WHO estimated that there was a 70 percent higher risk of females exposed as infants developing thyroid cancer over their lifetime. The thyroid is the most exposed organ as radioactive iodine concentrates there and children are deemed especially vulnerable.
The report concluded that for the general population inside Japan, the predicted health risks were low, but that one-third of emergency workers were estimated to have increased risk.
But there was no discernible increase in health risks expected outside Japan, the WHO in a 200-page report, which was based on a comprehensive assessment by international experts.
