Accounting for climate in ranking countries' carbon dioxide emissions
Increased concern about carbon dioxide emissions has resulted in efforts to create methods for ranking countries according to their emissions. Such rankings inform policy decisions on an international scale; the more comprehensive these rankings are, the better our chances of reducing emissions. It...
Benefits of recent improvements in vehicle fuel economy on overall fuel consumption and emissions
For the past several years, we have calculated (on a monthly basis) the average, salesweighted fuel economy of all light-duty vehicles (cars, pickup trucks, vans, and SUVs) sold in the U.S. The results indicate that, from October 2007 to September 2012, the average fuel economy has improved by 18...
Carbon capture in vehicles a review of general support, available mechanisms, and consumer acceptance issues.
This survey of the feasibility of introducing carbon capture and storage (CCS) into light vehicles started by reviewing the level of international support for CCS in general. While there have been encouraging signs that CCS is gaining acceptance as a means to reduce carbon emissions, the overall...
LEDs and power consumption of exterior automotive lighting implications for gasoline and electric vehicles.
This study evaluated the power consumption of traditional and LED-based exterior lighting systems on passenger vehicles, examining nominal consumption as well as realistic consumption based on real-world usage patterns of various lighting equipment. The results indicate that an all-LED system...
Where to live in the United States combined energy demand for heating and cooling in the 50 largest metropolitan areas.
The 50 largest metropolitan areas in the United States were examined to estimate the combined energy demand per person for residential heating and cooling. The analysis used heating and cooling degree days data to produce a combined index of total energy demand for climate control. The main results...
Environmental and energy implications of plug-in hybrid-electric vehicles.
We analyze the effect of charging a significant number of plug-in hybrid vehicles (PHEVs) in the United States using presently available night-time spare electric capacity in the short term and new base-load capacity in the long term. Nationwide, there is currently ample spare night-time utility...
Vehicle capacity and fuel consumption in household fleets constraint-based microsimulation mode.
Vehicle capability is one of the factors that constrain the set of transportation options available for personal transportation. The capacity for carrying passengers and cargo is of particular interest when energy consumption is considered, because the use of more efficient vehicles may be limited...
Potential energy demand for cooling in the 50 largest metropolitan areas of the world: Implications for developing countries
Air conditioning of dwellings in developing countries is currently rather rare, but increasing personal income is expected to change that. This study examined the potential energy demand for cooling in the 50 most populous metropolitan areas of the world, and assessed the incremental demand in...
Energy-demand consequences of the recent geographical shift in the metropolitan population of the US
This study examined how the population shift in the United States between 1960 and 2006 affected the energy demand for heating and cooling. Three analyses were performed. The first analysis was based on climatological considerations only. The second analysis added the energy efficiencies of heating...
PHEV marketplace penetration An agent based simulation.
Energy security and climate change issues have increased the call for improved energy efficiency from all sectors of the economy, especially the transportation sector. While vehicle manufacturers can in principle make their current vehicle offerings more fuel efficient, historically they have not...
