“…Estimation of the overall impacts of the state-level mitigation measures for transportation relies heavily on the US Department of Energy's Transportation Energy Data Book (Davis and Diegel, 2006). Baseline gasoline and ethanol usage are based on federal motor gasoline receipts (US FHWA, 2006), and baseline data on new light-duty vehicle sales are derived from Polk data (from NADA, 2006).…”

Many diverse actions can be taken to reduce greenhouse gas (GHG) emissions. Increasingly in the United States, policy-makers at subnational levels are setting emission targets and implementing plans for sector-specific GHG reductions. In this paper, local, state, and regional policy actions in the US are inventoried and analyzed as to their potential effect on national emissions. The realization of all existing subnational initiatives, as of September 2007, could stabilize US emissions at 2010 levels by the year 2020. The scale of these many decentralized mitigation actions, and their tendency to follow consistent steps, provide a counterpoint to oft-cited drawbacks of decentralized environmental policy. It also indicates that the US has been more committed to climate change mitigation than is generally acknowledged. r

“…Ford started producing its own OEM NGVs in the late 1980s. As a result of the Energy Policy Act (EPACT) of 1992, the market share of NGVs has grown significantly, as they are primarily adopted by government light-duty vehicle fleets (Davis and Diegel, 2006;EIA, 2000).…”

An empirical analysis on the adoption of alternative fuel vehicles: The case of natural gas vehicles

The adoption of alternative fuel vehicles (AFVs) has been regarded as one of the most important strategies to address the issues of energy dependence, air quality, and, more recently, climate change. Despite decades of effort, we still face daunting challenges to promote wider acceptance of AFVs by the general public. More empirical analyses are needed to understand the technology adoption process associated with different market structures, the effectiveness of regulations and incentives, and the density of infrastructure adequate to reach sustainable commercial application. This paper compares the adoption of natural gas vehicles (NGVs) in eight countries: Argentina, Brazil, China, India, Italy, New Zealand, Pakistan, and the US. It examines the major policies aimed at promoting the use of NGVs, instruments for implementing those policies and targeting likely stakeholders, and a range of factors that influence the adoption of NGVs. The findings in this paper should be applicable to other AFVs. r

“…Over 97% of the 2.7 trillion miles Americans drove in 2005 were fueled by petroleum-derived gasoline and diesel, which is now commonly being mixed with up to 10% ethanol as a replacement for methyl tertiary-butyl ether, or MTBE, in reformulated gasoline (1,2). Thus, to project the water quantities used for driving on various fuels, one simply needs to multiply the results of this paper by a target number of miles.…”

As the need for alternative transportation fuels increases, it is important to understand the many effects of introducing fuels based upon feedstocks other than petroleum. Water intensity in "gallons of water per mile traveled" is one method to measure these effects on the consumer level. In this paper we investigate the water intensity for light duty vehicle (LDV) travel using selected fuels based upon petroleum, natural gas, unconventional fossil fuels, hydrogen, electricity, and two biofuels (ethanol from corn and biodiesel from soy). Fuels more directly derived from fossil fuels are less water intensive than those derived either indirectly from fossil fuels (e.g., through electricity generation) or directly from biomass. The lowest water consumptive (<0.15 gal H 2 O/mile) and withdrawal (<1 gal H 2 O/mile) rates are for LDVs using conventional petroleumbased gasoline and diesel, nonirrigated biofuels, hydrogen derived from methane or electrolysis via nonthermal renewable electricity, and electricity derived from nonthermal renewable sources. LDVs running on electricity and hydrogen derived from the aggregate U.S. grid (heavily based upon fossil fuel and nuclear steam-electric power generation) withdraw 5-20 times and consume nearly 2-5 times more water than by using petroleum gasoline. The water intensities (gal H 2 O/mile) of LDVs operating on biofuels derived from crops irrigated in the United States at average rates is 28 and 36 for corn ethanol (E85) for consumption and withdrawal, respectively. For soyderived biodiesel the average consumption and withdrawal rates are 8 and 10 gal H 2 O/mile.
