Hot as Hell: Firefighting foam heats up coal fire debate in Centralia, Pa.

By some accounts, Hell on Earth is located directly below Centralia, Pa.: Smoke rises from the cracked ground, smoldering sinkholes open without warning, and what is left of the town’s abandoned houses and surrounding woodlands is scorched and covered in a layer of smelly sulfur.

West Virginia Coal: Dirty water, dirtier politics - but will there be a cleaner future?

Coal has always been king in West Virginia. For more than 250 years, the mining industry has ruled the Mountain State, sometimes running roughshod over worker’s rights, public safety and West Virginia’s mountain ecosystems in the push for higher yields. Coal mining is not without its benefits: West Virginia’s mines produce 15 percent of our country’s coal and half of our coal exports.
