A Data Envelopment Analysis Model For Renewable Energy Technology Selection, Elif Kongar, Kurt A. Rosentrater Apr 2009

A Data Envelopment Analysis Model For Renewable Energy Technology Selection, Elif Kongar, Kurt A. Rosentrater

Kurt A. Rosentrater

Public and media interest in alternative energy sources, such as renewable fuels, has rapidly increased in recent years due to higher prices for oil and natural gas. However, the current body of research providing comparative decision making models that either rank these alternative energy sources and/or determine the best possible alternatives is still limited. This paper aims at filling this gap by proposing a Data Envelopment Analysis (DEA) model structure for ranking energy source alternatives under varying circumstances. The model considers both the economics of energy sources and additional environmental criteria such as CO2 emissions and damage cost. Numerical examples …


Quantifying Total And Sustainable Agricultural Biomass Resources In South Dakota—A Preliminary Assessment, Kurt A. Rosentrater, Dennis Todey, Russell Persyn Jan 2009

Quantifying Total And Sustainable Agricultural Biomass Resources In South Dakota—A Preliminary Assessment, Kurt A. Rosentrater, Dennis Todey, Russell Persyn

Kurt A. Rosentrater

Conversion of biomass is considered the next major advance in biorenewable fuels, energy, and products. Wholesale conversion to biomass utilization could result in removal of current crop residues from agricultural fields (on prime agricultural lands) or even implementation of different crops and cropping strategies (i.e., switchgrass on marginal lands). To date, the driver for biomass processing has been economics and limitations on the conversion of the lignocellulose. Over the last forty years significant investments and resultant changes in management practices in the agricultural sector have focused on soil and water conservation. One of the major efforts has focused on conservation-till …
