The project provides an updated Energy Return on Investment (EROI) for Enhanced Geothermal Systems (EGS). Results incorporate Argonne National Laboratory's Life Cycle Assessment and base case assumptions consistent with other projects in the Analysis subprogram. EROI is a ratio of the energy delivered to the consumer to the energy consumed to build, operate, and decommission the facility. EROI is important in assessing the viability of energy alternatives. Currently EROI analyses of geothermal energy are either out-of-date, of uncertain methodology, or presented online with little supporting documentation. This data set is a collection of files documenting data used to calculate the Energy Return On Investment (EROI) of Engineered Geothermal Systems (EGS) and erratum to publications prior to the final report. Final report is available below, or from the OSTI web site (http://www.osti.gov/geothermal/). Data in this collections includes the well designs used, input parameters for GETEM, a discussion of the energy needed to haul materials to the drill site, the baseline mud program, and a summary of the energy needed to drill each of the well designs. EROI is the ratio of the energy delivered to the customer to the energy consumed to construct, operate, and decommission the facility. Whereas efficiency is the ratio of the energy delivered to the customer to the energy extracted from the reservoir.

Intermodal Freight Facilities Air-to-TruckThis feature layer, utilizing data from the Bureau of Transportation Statistics (BTS), displays Air-to-Truck Intermodal freight facilities within Puerto Rico and the U.S. This layer, per BTS, "can be used to understand the intermodal connections for freight transfer and may be used for analysis, spatial mapping, and transportation modeling." It "includes air to truck intermodal freight facilities for the top 60 airports by total freight moved and is one of several layers in the Bureau of Transportation Statistics (BTS) Intermodal Freight Facility Database."Minneapolis-St Paul International Airport Air to Truck Intermodal FacilitiesData currency: This cached Esri service is checked monthly for updates from its federal source (Intermodal Freight Facilities Air-to-Truck)Data modification: noneFor more information: Intermodal Transportation DatabaseFor feedback, please contact: ArcGIScomNationalMaps@esri.comBureau of Transportation StatisticsPer BTS, "The Bureau of Transportation Statistics (BTS), part of the Department of Transportation (DOT) is the preeminent source of statistics on commercial aviation, multimodal freight activity, and transportation economics, and provides context to decision makers and the public for understanding statistics on transportation."
