For decades now, wind turbines have been generating electricity more cheaply than most other (non-hydro) renewable energy technologies. In particular, wind has maintained a comfortable lead over...
Wind and the Environment: The EPA's Tech Divide
Does the Clean Air Act require the agency to consider the most low-emission coal plant technologies in permitting new plants?
catalytic reduction (SCR) for conventional pulverized coal power plants are installed only to control emissions, as they have no other purpose. For such technologies, a regulatory push may be essential to ensure adoption, especially of the latest, most effective, and most expensive options as they become available.
In contrast, alternative designs such as IGCC, like alternative fuels—whether natural gas or lower sulfur coal—go well beyond consideration of emissions. These alternatives, after all, affect choices that might not be limited to emissions control, since they relate to equipment, processes, operating considerations and even plant-siting choices beyond whether to install add-on emissions-control technology.
Meanwhile, the ongoing legal challenges, coupled with the divergence in approach between the EPA and certain states, create a legal ambiguity that could affect development of IGCC as well as processes for approval and development of plants needed to meet growing energy demand. Unless Congress intervenes through enactment of clarifying legislation, the state and federal legal landscape surrounding the approval of new coal-fired power plants may remain murky and unsettled for the foreseeable future, as the federal cases proceed and as the states continue to experiment with, and refine, their own policies. The course of the debate could have a substantial effect not only on the future of IGCC but also on the interface between energy policy and environmental policy.
