Natural Gas Dethrones King Coal As Power Companies Look To Future It's a brave new energy world, with two major opponents: natural gas and coal. As prices fluctuate and renewables, such as wind and solar, fight for a share of energy generation, there's heated competition for access to your wall socket.

From NPR News this is ALL THING CONSIDERED. I'm Audi Cornish.


And I'm Melissa Block. The way Americans get their electricity is changing. Coal is in decline, natural gas is bursting out of the ground in record amounts, and wind and solar energy are growing fast. As NPR's Christopher Joyce reports, all this is happening as power companies are trying to choose what kind of energy to bet on for the next several decades.

CHRISTOPHER JOYCE, BYLINE: If you trace the electricity from your wall socket back to where it came from, usually you'd find a power plant - a smokestack, steam generators, cooling towers. Until recently, half of these plants burned coal to make electricity. Now it's down to about one-third. Since 2010 about 150 coal plants have either been retired or they've announced they will retire soon.

What knocked king coal off its throne? Mostly natural gas.

TREVOR HOUSER: We added almost twice as much natural gas capacity as we retired coal capacity last year.

JOYCE: That's Trevor Houser, an energy analyst with the Rhodium Group in New York. Why gas?

HOUSER: That is primarily because of the price.

JOYCE: The price of gas is well below what it was a few years ago. That's mostly because of hydraulic fracturing technology that reaches more gas reserves, and also because of a weak economy that's lowered demand for electricity. And there's plenty more gas to come. Yesterday, 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 gas, gas prices have crept up.

HOUSER: As natural gas prices have started to increase over the past few months, coal's share of U.S. power generation has increased right alongside it.

JOYCE: So this is the brave new energy world of the 21st century. Two evenly matched opponents, natural gas providing 30 percent of our electricity, coal a half a dozen percentage points above that and trying to halt its downward spiral. Add in hydro, wind and solar-powered electricity, which have surged to about 12 percent of our power, and you've got heated competition for access to your wall socket.

And the future of electric power is at stake here. Coal plants are closing. Nuclear power is not growing. The economy is picking up. That means more demand for electricity. Revis James analyzes the market for the utility industry's Electric Power Research Institute.

REVIS JAMES: 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.

JOYCE: New capacity, new power plants that will determine what kind of energy American use for the next 50 years or so. Gas would seem to be the economical choice but here's the rub. The gas fuel, rather than the cost of building the equipment to burn it, is 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.

JAMES: The real $64 question is what will happen to gas prices as the power sector's consumption of gas starts to significantly increase?

JOYCE: 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 wagon when gas prices are so volatile. Bruce Nilles is hoping they don't. Nilles is a lawyer with the Sierra Club, which has spent the last 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 would divert the country away from the cleanest energy - wind, solar and geothermal power.

BRUCE NILLES: What we're trying to avoid is building hundreds of new gas plants, locking us in for the next 20, 30 years and thereby making it impossible to make the swifter transition to clean energy.

JOYCE: Nilles says it's a race. Coal is slowing down, renewables are closing the gap, and natural gas is a dark horse coming up on the outside. Christopher Joyce, NPR News.
