Coal and Transportation Modeling, It is generally recognized that expanded coal use, while presenting some serious environmental and ecological problems, can allow Canada and the United States time to plan to develop alternate energy sources before world oil reserves reach a critical level.

Modeling U.S. Coal Supply and Demand,lternative fuel. In assessing the outlook for coal, we must carefully analyze the economics of mining, transporting, and burning coal; as well as political, social, and environmental implications. One effort to better understand the interplay of these forces is the Energy Modeling Forum study entitl

Coal Slurry Pipelines: A Technology Assessment,d legal-regulatory implications of coal slurry pipeline development. Major findings include: (1) under certain conditions slurry pipelines are the least costly mode for transporting coal; (2) the current regulatory framework does not insure an optimal choice between rail and pipeline from a societal

Simulation of Tar Sands Mining Operations,The energy crisis is upon us and new sources of energy must be tapped. One such pool is the vast reserves of the Athabasca Tar Sands in Alberta, Canada. Of the estimated 600 billion barrels of oil locked in the sands, 300 billion barrels are deemed recoverable. The problem has been to extract the oil by a method both feasible and economic.
