From NPR News, this is ALL THINGS CONSIDERED. I'm Melissa Block.


And I'm Audie Cornish.

Now, we're going to explore the impact of cheap natural gas in the U.S. The boom in natural gas is a good thing for the environment. That's because, relatively, clean gas is replacing dirty coal-fired power plants. In the long run, though, cheap natural gas could slow the growth of even cleaner sources of energy, such as wind and solar power.

NPR's Richard Harris explains.

RICHARD HARRIS, BYLINE: The process of fracking for natural gas has stirred a lot of local opposition. But many people looking at cheap gas from the global perspective see it as a good thing. Henry Jacoby at MIT says cheap energy will help pump up the economy.

HENRY JACOBY: Overall, this is a great boon to the United States. It's not a bad thing to have this new and available domestic resource. But we have to keep our eye on the ball long-term.

HARRIS: His long-term concern is what cheap gas will do to much cleaner sources of energy. Wind and solar power are more expensive than natural gas. And though those prices have been coming down, they're chasing a moving target that has fallen fast: natural gas.

JACOBY: It makes the prospects for large-scale expansion of those technologies more chancy.

HARRIS: From an environmental perspective, natural gas could help transition our economy from fossil fuels to clean energy. It's often portrayed as a bridge fuel to help us through the transition because it's so much cleaner than coal and it's abundant. But Jacoby says that bridge could be in trouble if cheap gas kills the incentive to develop renewable energy.

JACOBY: You better be thinking about a landing of the bridge at the other end. If you forget to have a landing at the other end, then it's just a bridge to nowhere.

HARRIS: In the short run, at least, the wind industry isn't too worried about this. Denise Bode heads the American Wind Energy Association. She says low gas prices don't undercut current prices for wind because those are mostly fixed by long-term deals.

DENISE BODE: We really focus on getting our money out of a 20-year contract. It's not really based on a market price.

HARRIS: And even if wind is a bit more expensive than natural gas, she says utilities still want it in their mix. Windmills aren't subject to changing fuel prices, so the cost to production is quite predictable. That's not true for natural gas. There's no guarantee that today's cheap prices will stay as low as some predict.

BODE: It's very difficult to really know how certain that is. And so you always want to balance it with something that is certain.

HARRIS: What really worries Bode isn't natural gas, it's politics. Wind could lose a huge tax break at the end of this year, and that would have a much more dramatic effect than low natural gas prices.

The government's Energy Information Administration, the EIA, predicts a precipitous drop in construction of new wind farms unless the federal production tax credit is renewed.

BODE: You'll see very low numbers. In fact, EIA, I think, projects almost zero for 2013.

HARRIS: Solar subsidies run for several more years, so they're not in that bind, at least not yet. But Trevor Houser, an energy analyst at the Rhodium Group, says these tax credits and other incentives like state renewable standards are key if renewables are to grow and mature during the natural gas glut.

TREVOR HOUSER: Long-term renewable deployment in the U.S., I think, is going to depend primarily on policy. Is there enough concern about environmental consequences to put in place incentives for renewable energy?

HARRIS: And that partly depends on how much of a premium people and companies will be willing to pay for cleaner energy. Right now, with natural gas so cheap, that premium is fairly substantial.

HOUSER: If those type of prices hang around for another three, four years, then I think you'll definitely see reduced political will for renewable energy deployment. But we don't expect prices that low to stay around that long, because low prices are, in many ways, self-correcting.

HARRIS: Gas is so cheap now that companies that produce it are struggling to make a profit. So Houser expects prices to move up, and that will help close the price gap between gas and renewable energy.

Even so, there's still a huge way to go before prices and government policies do enough to significantly reduce emissions of the gases that contribute to global warming.
