Pipelines are center stage in a fight over the nation's energy future, concerns about climate change and private property rights. Donald Trump's election means the battles are likely to continue.

More than 100 nations will sign the climate change deal agreed to in December. It will eventually commit nealy all the world's governments to cut back on greenhouse gases that cause global warming.

The sudden ups and downs of the oil and gas industry can feel like whiplash for rural communities seeing an influx of workers. Affordable housing has been a challenge. With the current slowdown in drilling, rental prices have dropped, but they're still much higher than they were pre-boom, leaving low-income and senior people still struggling to find a place they can afford.

Driven by new regulations and fracking, more coal power plants are retiring for cheaper, cleaner-burning natural gas. But scientists have yet to work out the fossil fuel's imperfect climate footprint.

Anti-fracking activists say they're being targeted by law enforcement agencies that work with the oil and gas industries to monitor threats to infrastructure.

Environmental groups cheered New York's decision to ban the practice, and some in the industry say when it comes to good-paying jobs, New York's loss is Pennsylvania's gain.

Most of the noise created by natural gas development is temporary. After drilling and fracking, the workers and equipment are gone. But compressor stations can stay noisy for years — even decades.

One of the biggest natural gas companies in the U.S. is facing legal trouble over allegations it cheats landowners out of royalty money. Chesapeake Energy has faced similar accusations across the U.S.

Pennsylvania is the fastest-growing state for natural gas production, but the development is cutting through swathes of previously unbroken forests. Some scientists say this could affect wildlife, which perform important functions like climate and insect control.

Surrounded by scenic pastoral landscape, a restaurant in Lancaster County, Pa., has a lot of tongues wagging over its signature beef dish, called "The Truth." Its fans like knowing exactly where their meat is coming from.
