 Wyoming's latest energy boom started in the late 1990s and exploded in the early 21st century.In response, the Wyoming Outdoor Council has shifted much of its focus toward watchdogging the unprecedented, fast-paced development of natural gas fields, coal-bed methane operations, utility-scale wind farms, a proposed coal-to-liquids plant and four proposed new coal-fired power plants in the state.“The boom that began in the 1990s now influences all aspects of our work to protect Wyoming’s public lands and wildlife, as basin after basin fills with drill rigs,” the group wrote in its Fall 2007 newsletter.
