Overview: Albertans have traditionally been proud of their mighty petroleum industry. But lately, they have begun to question how that industry works. Nowhere is this shift more apparent than along the Clearwater River in Central Alberta, near Rocky Mountain House. There, residents are opposing Shell Canada's plans to drill a sour gas well in their area. The sour gas from the well could generate $10,000 a day in gross revenue, to meet today's high energy demands.
