Response of California temperature to regional anthropogenic aerosol changes

Description: In this paper, we compare constructed records of concentrations of black carbon (BC)--an indicator of anthropogenic aerosols--with observed surface temperature trends in California. Annual average BC concentrations in major air basins in California significantly decreased after about 1990, coincident with an observed statewide surface temperature increase. Seasonal aerosol concentration trends are consistent with observed seasonal temperature trends. These data suggest that the reduction in ant… more

MARKAL-MACRO: An overview

Description: MARKAL-MACRO is an experiment in model linkage. This new tool is intended as an improvement over existing methods for energy policy assessment. It is designed specifically for estimating the costs and analyzing alternative technologies and policies proposed for reducing environmental risks such as global climate change or regional air pollution. The greenhouse gas debate illustrates the usefulness of linked energy-economy models. A central issue is the coupling between economic growth, the leve… more

Molecular Basis of Microbial One-Carbon Metabolism 2008 Gordon Research Conference (July 20-25, 2008)

Description: One-carbon (C-1) compounds play a central role in microbial metabolism. C-1 compounds include methane, carbon monoxide, CO2, and methanol as well as coenzyme-bound one-carbon compounds (methyl-B12, CH3-H4folate, etc). Such compounds are of broad global importance because several C-1 compounds (e.g., CH4) are important energy sources, some (e.g., CO2 and CH4) are potent greenhouse gases, and others (e.g., CH2Cl2) are xenobiotics. They are central in pathways of energy metabolism and carbon fixat… more

Response to: “Long-term effectiveness and consequences of carbon dioxide sequestration” by Gary Shaffer, published in Nature Geosciences, 27 June 2010.

Description: Shaffer’s (2010) article reports on the long term impact of less than perfect retention of anthropogenic CO2 stored in deep geologic reservoirs and in the ocean. The central thesis of this article is predicated on two deeply flawed assumptions. The first and most glaring is the implicit assumption that society has only one means of reducing greenhouse gas emissions, carbon dioxide capture and storage (CCS). Secondly, there is absolutely no geophysical nor geomechanical basis for assuming an exp… more

Radiative forcing and temperature response to changes in urban albedos and associated CO2 offsets

Description: The two main forcings that can counteract to some extent the positive forcings from greenhouse gases from pre-industrial times to present-day are the aerosol and related aerosol-cloud forcings, and the radiative response to changes in surface albedo. Here, we quantify the change in radiative forcing and land surface temperature that may be obtained by increasing the albedos of roofs and pavements in urban areas in temperate and tropical regions of the globe by 0.1. Using the catchment land surf… more

Comparison of Australian and US Cost-Benefit Approaches to MEPS

Description: The Australian Greenhouse Office contracted with the Collaborative Labeling and Appliance Standards Program (CLASP) for LBNL to compare US and Australian approaches to analyzing costs and benefits of minimum energy performance standards (MEPS). This report compares the approaches for three types of products: household refrigerators and freezers, small electric storage water heaters, and commercial/industrial air conditioners. This report presents the findings of similarities and differences bet… more

EARLY ENTRANCE COPRODUCTION PLANT

Description: The overall objective of this project is the three phase development of an Early Entrance Coproduction Plant (EECP) which uses petroleum coke to produce at least one product from at least two of the following three categories: (1) electric power (or heat), (2) fuels, and (3) chemicals using ChevronTexaco's proprietary gasification technology. The objective of Phase I is to determine the feasibility and define the concept for the EECP located at a specific site; develop a Research, Development, … more

Program analysis methodology Office of Transportation Technologies 2003 quality metrics final report.

Description: The purpose of this report is to describe the methodology and results obtained from a continuing DOE Office of Transportation Technologies (OTT) activity to estimate future effects of OTT projects on national energy use, petroleum consumption, criteria emissions, greenhouse gas emissions, and various measures of national income and employment. Assumptions are made about the future costs and characteristics of alternative vehicles and fuels. Models that take into account the value that vehicle b… more

Overview of electrochemical power sources for electric and hybrid-electric vehicles.

Description: Electric and hybrid-electric vehicles are being developed and commercialized around the world at a rate never before seen. These efforts are driven by the prospect of vehicles with lower emissions and higher fuel efficiencies. The widespread adaptation of such vehicles promises a cleaner environment and a reduction in the rate of accumulation of greenhouse gases, Critical to the success of this technology is the use of electrochemical power sources such as batteries and fuel cells, which can co… more

Multiproject baselines for evaluation of electric power projects

Description: Calculating greenhouse gas emissions reductions from climate change mitigation projects requires construction of a baseline that sets emissions levels that would have occurred without the project. This paper describes a standardized multiproject methodology for setting baselines, represented by the emissions rate (kg C/kWh), for electric power projects. A standardized methodology would reduce the transaction costs of projects. The most challenging aspect of setting multiproject emissions rates … more
