Murrey Jacobson talks with former National Public Radio reporter John McChesney, who has an online documentary, "An Unquiet Landscape: The American West's New Energy Frontier."
Jacobson writes: "At a time when it's difficult to find enough industries that are creating new jobs with good wages, the boom in energy development in the U.S. is an unexpected surprise that's fueling growth in some parts of the American West and potentially transforming some of the communities in question.
"This week,Ray Suarez and producer Merrill Schwerin look at the consequences and choices surrounding the new energy boom, a gold rush of sorts that's focused on oil and natural gas development rather than alternative energy sources.
"It's an important moment: Major finds and the use of advanced technologies to tap into reserves that were once unattainable could help reduce US dependence on foreign sources of oil in a way few had predicted just a few years ago and could lead to lower prices. But as Ray documents tonight in his piece about the oil boom in Williston, North Dakota - where unemployment is well below the national average and where people come from other states to find a job -- the energy boom comes with some serious trade-offs."
