ABSTRACT Nebraska is well endowed with water, particularly groundwater, but has few fossil fuel reserves. However, it is located adjacent to states which have almost no water but have enormous quantities of coal and oil shale. Recent court cases facilitate the movement of water from water-rich states such as Nebraska to water-short states, such as Colorado and Wyoming. The possibility of an energy-water partnership exists and raise numerous policy questions. Within Nebraska, energy consumption patterns are similar to those of the nation's, with consumption of electricity in the agricultural sector growing fastest. Water consumption in the state is dominated by agriculture, and future development of groundwater for...
Federal policymakers must not neglect to rationalize the allocation of jurisdiction between federal and state regulators, remove impediments to the expansion of the interstate transmission grid, and support the development of demand-side responsiveness to market pricing.
The purpose of this study was to develop land use projections for the middle of the next century. To separate the influence of climate change from other factors on land use, projections (a Central Projection and two variants) were made under both unchanged and changed climate. They cover the plausible range of alternative land claims of agriculture and urbanization. Impacts of climate change on land suitability as well as overall changes in the acreages of several land use categories are presented.
Desert tortoises, Gopherus agassizii, generally were active in the spring and fall. They often became active during and after infrequent showers and thunderstorms, and drank from temporary pools of standing water even when air temperatures were suboptimal (9-15 C). In several instances tortoises constructed shallow catchment basins which held water for as long as six h. Thus tortoises can obtain drinking water by modifying their environment. Following small amounts of rainfall (5.6 mm) in July 1976, six tortoises increased an average of 9.2% in body weight; this increase was due to ingestion of water. Drinking may be an important source of water for this species. Published in Herpetologica, volume 36, issue 4, on...

This article explores the institutional architecture in place to govern energy in the US and its underlying principles. More specifically, it identifies the key institutions involved with energy decision-making, with an emphasis on the national level and key legislative acts of the past four decades. The second section explores six historic guiding principles connected with national energy production and use, and the third section identifies how each of these conditions is eroding. The fourth section highlights the general implications of this shift for energy governance, namely that energy decision-making is now complex, inconsistent, vertically and horizontally fragmented and politicized.
In petroleum industry, the difference between pore pressure (Pp) and minimum horizontal stress Sh (termed the seal or retention capacity) is of major consideration because it is often assumed to represent how close a system is to hydraulic failure and thus the maximum hydrocarbon column height that can be maintained. While Sh and Pp are often considered to be independent parameters, several studies in the last decade have demonstrated that Sh and Pp are in fact coupled. However, the nature of this coupling relationship remains poorly understood. In this paper, we explore the influences of the spatial pore pressure distribution on Sh/Pp coupling and then on failure pressure predictions and trap integrity evaluation....
In this article, the Lovins'[2] explain what is meant by Natural Capitalism, four principles that enable business to behave responsibly towards both nature and people while increasing profits, inspiring their workforce and gaining competitive advantage. It combines radically increased resource productivity; closed-loop, zero-waste, nontoxic production; a business model that rewards both; and reinvestment in natural capital. The article describes how, even today, when nature and people are typically valued at zero, protecting and restoring nature, culture and community can be far more profitable than liquidating them.
The manufacturing sector in developing countries accounts for a steadily increasing share of world energy consumption and global greenhouse gas emissions. This paper is based on a study on policies to stimulate improvement of energy efficiency in the industrial sector in developing countries. The paper highlights developments in respect of the efficiency of industrial energy use in Africa, Asia and Latin America. The paper begins to outline some salient features of energy and technology use in four energy-intensive industries. Subsequently, recent policy initiatives and institutional development in support of rational use of energy (RUE) in industry are considered. The paper concludes with national policy priorities...

The history of hydrocarbon generation, expulsion and migration from the Upper Devonian Bakken and Mississippian Lodgepole source rocks in the Williston Basin has been successfully replicated by a 330-km long TEMISPACK model, running from the centre of Williston Basin to the Wapella oilfield in Saskatchewan. The model shows that oil generation is the cause of overpressures in the Bakken Fm., where shale vertical permeabilities must be as low as 10-2-10 -3 nD when overpressures are around 15 MPa. Hydraulic fracturing threshold was not commonly reached. Yet, our model suggests that expulsion efficiencies are as high as 0.85. Observed very low Bakken shale porosities (0.03) are entirely consistent with this result....
