Physical and Economic Models of Natural Resource Scarcity: Theory and Application to Petroleum Development and Production in the Lower 48 United States, 1955-1985
Physical and economic models of the costs of developing and producing petroleum in the lower 48 United States were calculated and compared for the 1955 to 1985 period. The physical scarcity model calculated the energy return on investment (EROI) for petroleum development and production. The EROI is …

Environmental and economic tradeoffs of feedstock usage for liquid fuels and power production
… is divided into two parts - 1) assessing the energy return on investment for alternative jet fuels, and 2) quantifying the tradeoffs associated with the aviation and non-aviation use of agricultural residues. We quantify energy return on energy investment (EROI) as one metric for the …
