Tag Archives: EROEI
In this article we focus on the use of EROEI, or energy efficiency, to compare traditional and non-traditional energy resources. We assess two different methods for calculating EROEI and provide data in support of one method over the other. A description of the selected method is presented using our calculation of the EROEI for the production of gas at the Srednje-Vilyuysk Gas Condensate Deposit.
This article discusses criteria for comparing the effectiveness of energy resources. It focuses on the interrelationship between the effectiveness of energy resources and movement from one technological stage to another. What emerges is the consistent pattern of change in existing technologies, and increasingly evident is that, at their current stage of development, neither nano- nor biotechnology will lead to an evolution from the current and fifth technological stage to a sixth. Of note is that at present oil remains the key energy resource, which means that in the near future peak oil will force us to confront an unprecedented event in industrial history: energy degradation, which can be viewed as a regressive movement in the existing technological stage.
In case with peak oil and rising oil prices, in the nearest future more attention will be given to finding alternatives to conventional oil, as in the form of new energy sources, and as new technologies for production of liquid fuels. For investment business, technological cases, development of energy strategies we must be able to evaluate and compare various energy sources and technologies of fuel. The paper examines the criteria for comparing the efficiency of energy resources and technologies, among the criteria can be identified: industrial-technological, environmental, economic, consumer criteria.
