THE LONG-RANGE ENERGY PERSPECTIVE

The author reviews general questions affecting energy projections and goes on to examine reserve forecasts for each type of energy. The last part of the paper considers consumption forecasts and makes an assessment of the likely situation in the year 2000.     

On recycling as a moot environmental issue

Recycling of household wastes may not contribute as much toward a solution to environmental problems as widely supposed. It runs into practical problems often overlooked by nonspecialists. Recycling can also contribute significantly to pollution. Most important, recycling may use up larger quantities of materials than it saves. The note ends up with a model in which recycling will always cause a net loss in real resources. It is concluded that the subject requires more exploration rather than decision making by prejudgment and emotion.     

A simulation model for the management of low density recreational areas

In order to take account of the congestion externalities associated with increased use intensity during a given period at a low density recreational resource, it is necessary to determine the effects of alternative use levels on the expected quality of each individual's experience. This paper describes a simulation model for wilderness recreation designed to provide such measures. In order to illustrate the model it is applied to the Spanish Peaks Areas in Montana.
