Recycling in road construction or resurfacing is much more than simply re-using excavated material, it is a combination of reducing the carbon footprint and, at the same time, using materials that would be sent to landfill or require anti-contamination treatment. This article discusses the benefits of a sustainable approach across Staffordshire.
A mathematical model was designed for computer analysis of the likely impact of energy development in the upper Colorado River Basin in the period 1980 to 1985. The upper Colorado River Basin, with its reserves of coal, oil shale, uranium ore, petroleum, and natural gas is regarded as an important source of increased energy resources. The Basin now contains several major mature oil fields, seven major hydroelectric facilities, and has produced the major portion of uranium mined in the U.S. Energy projects proposed, planned, or under construction in the Colorado, Utah, and Wyoming portions of the Basin in 1977 include 39 new or expanded coal mines, 10 new or expanded thermoelectric power plants, eight oil shale developments, one coal gasification plant, and three tar sand projects, with the possibility of increased uranium mining and milling. The model is an interregional input-output depiction of economic activity coupled with export, water, and energy resource constraints and runs in a linear optimized framework. (CH)
This paper reviews the current relationship between water resources and energy development in New Mexico, with special emphasis on the San Juan and western Rio Grande basins. It examines the various ways in which the water used in energy extraction and processing may be acquired by the energy developer. Both supply-side and demand-side options are explored, and the conclusion is drawn that the source of water most attractive to the developer will be that which may be bought in the water market. The paper goes on to examine what this strategy would mean for New Mexico in the near future. It suggests that price competition for water would have only a minor impact on agricultural production if extensive future energy developments focused on the proposed coal-fired steam-electric plants and coal extraction for export by rail. This conclusion, however, rests upon two assumptions: that water markets operate efficiently and that there exists an enlightened public water policy.
