GEOTHERMAL ENERGY RESOURCE POTENTIAL Geothermal energy is a renewable resource that provides energy employing various applications and resource types. Geothermal plants using deep resource temperatures between ~200°F and 700°F have been producing commercial power in the United States since the 1960s (GEA, 2012)

They are thus able to provide baseload power unlike renewable sources such as wind and solar.4 Comments on the CSM Analysis of Geothermal Energy CSM evaluated sites for geothermal energy resource development by overlaying DOE sites with a geothermal resource map, focusing on commercial hydrothermal systems. CSM found four sites to have geothermal energy resource potential.

Comments on CSM Analysis of Coal and Uranium Resources Coal was included in the NREL/CSM analysis by way of a cursory review by CSM, but it might have been included in greater depth because it was included in the request for the study in the Omnibus Appropriations Act of 2009. The CSM analysis used regional resource maps rather than site characterizations.

Comments on the NREL Analysis of Biomass Energy NREL used its REopt tool to model biomass systems on DOE sites for generation of electric power. Assumptions included that the biomass was to be purchased, brought on-site, and combusted to generate electricity.

Characterization of LFG candidate facilities is necessary to identify a consistent gas quality and quantity over the energy production time period. A particular concern for DOE sites is the additional cost to transport the LFG from the landfill source to a nearby DOE facility for power production and various right-of-way issues.

Natural gas is used in electricity generation, for heating buildings, and as a feedstock for chemicals and other industrial processes. Benefits and Challenges of Oil and Natural Gas Production Domestic oil and gas production increases have led to decreased prices for these commodities in the United States as well as increased manufacturing in the United States due to lower costs for energy and raw materials.

From page 26... ...
Comments on the CSM Analysis of Oil and Gas Energy Production The evaluation of oil and natural gas resources on DOE lands was undertaken by CSM. Screening criteria for the DOE sites were as follows: land area greater than 160 acres, land in a sedimentary basin, active drilling in the basin, and active drilling nearby to the site.
