Drivers everywhere are feeling pain at the pump. With gas prices hovering at $4.00 a gallon in many areas, many of us are trying to reduce the amount of driving we do. Combining trips, switching to public transportation, walking, and biking can all help reduce our personal use, at least in the short run. According to the Department of Energy, demand for gas recently dropped. Transportation is responsible for more than two-thirds of U.S. oil consumption, and about 60 percent of the oil we use must be imported. Dependence on imported oil leads to concerns over vulnerability to disruptions, especially if world oil production peaks. Use of gasoline in vehicles also accounts for one-third of U.S. emissions of carbon dioxide (CO2), the main greenhouse gas linked to global climate change. The U.S. government is seeking to reduce the use of oil to help meet both challenges. A longer-term solution to the oil problem would be to invest in and encourage research in systems that are more energy efficient, and new technologies that do not rely on gasoline.
The National Research council has produced a number of reports on the subject of energy, summarizing our current status and examining prospects for the future. Transitions to Alternative Transportation Technologies — Plug-in Hybrid Electric Vehicles (PHEVs) evaluates battery and vehicle technologies to predict how costs might drop as technology improves and economies of scale increase and examines the ability of the electric grid to supply power for a growing PHEV fleet. It also analyzes two potential market-penetration rates for PHEVs.
Assessment of Fuel Economy Technologies for Light-Duty Vehicles states that a significant number of technologies exist that can reduce the fuel consumption of light-duty vehicles while maintaining similar performance, safety, and utility. Each technology has its own characteristic fuel-consumption benefit and estimated cost. Although these technologies are often considered independently, there can be positive and negative interactions among individual technologies, and so the technologies must be effectively integrated into the full vehicle system.
America’s Energy Future: Technology and Transformation discusses ways that, with a sustained national commitment, the United States could obtain substantial energy efficiency improvements, new sources of energy, and reductions in greenhouse gas emissions through the accelerated deployment of existing and emerging energy-supply and end-use technologies.
These books and others on the subject can inform debate and assist in decision-making.
