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...
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...
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...
Air conditioning versus heating: Climate control is more energy demanding in Minneapolis than in Miami.
Energy demand for climate control was analyzed for Miami (the warmest large metropolitan area in the US) and Minneapolis (the coldest large metropolitan area). The following relevant parameters were included in the analysis: (1) climatological deviations from the desired indoor temperature as...
Distance driven and economic activity in the individual U.S. States: 1997-2011.
During these times of heightened concern about energy and the environment, it is desirable to have relatively high economic activity per unit of driving. Thus, this study examined the current variations among the U.S. states and the District of Columbia in GDP per distance driven and the recent...
Will AC put a chill on the global energy supply?
The United States currently uses more energy for air- conditioning than all other countries combined—a sobering statistic from Stan Cox of the Land Institute in Salina, Kansas. That distinction might not remain true for long, however. Several developing countries rank among both the most populous...
Making driving less energy intensive than flying
This report analyzes recent trends in the amount of energy needed to transport a person in the U.S. a given distance either in a light-duty vehicle or on a scheduled airline flight. After observing that the energy intensity of driving (BTU per person mile) is 57% greater than that of flying,...
