  • In 1995, the U.S. Department of Energy through Argonne National Laboratory`s Center for Transportation Research sponsored energy efficiency data collection from the student, private, and professional vehicles during the American Tour de Sol. The American Tour de Sol is a multiple-day road rally event run from New York City to Washington, D.C. As part of this efficiency testing, a number of vehicles were tested on a chassis dynamometer utilizing three common drive cycles: the LA-4, the New York City Cycle, and the Highway Fuel Economy Test. The results demonstrate remarkable efficiency increases over a gasoline control vehicle and significant cycle-sensitivitymore » information. Two series hybrid electric vehicles (HEVs) were shown to have fuel efficiencies which were less sensitive to drive cycle than either a gasoline or an electric vehicle.« less
  • In 1994, the US Department of Energy, through Argonne National Laboratory`s Center for Transportation Research, sponsored energy-efficiency data collection from student, private, and professional electric vehicles during the American Tour de Sol (ATdS). The ATDS is a multiple-day road rally event, from New York City to Philadelphia. During each leg of the event, kilowatt-hour meters measured the efficiency of the electric vehicles (EVs), which averaged from 5.68 to 65.74 km/kWh. In addition to daily energy-usage measurements, some vehicles used a data-acquisition unit to collect second-by-second information. This showed, in one case, that 21% of the total energy was captured inmore » regenerative braking. Some of the vehicles were also tested on a dynamometer for energy-efficiency, acceleration, and steady-state power ratings. This paper also compares the energy efficiency of the vehicles during the road rally to the dynamometer results. In almost all vehicles, there was an increase in energy efficiency when the vehicle was traveling over the road, due to the non-transient duty cycle and efficient driving techniques. The dynamometer testing also showed that some EVs are equal to or better than gasoline vehicles in performance and efficiency.« less
  • The U.S. Department of Energy's (DOE's) GeoPowering the West (GPW) program works with the U.S. geothermal industry, power companies, industrial and residential consumers, and federal, state, and local officials to provide technical and institutional support and limited, cost-shared funding to state-level activities. By demonstrating the benefits of geothermal energy, GPW increases state and regional awareness of opportunities to enhance local economies and strengthen our nation's energy security while minimizing environmental impact. By identifying barriers to development and working with others to eliminate them, GPW helps a state or region create a regulatory and economic environment that is more favorable formore » geothermal and other renewable energy development. Electricity is produced using expanding steam or very hot water from the underground reservoir to spin a conventional turbine-generator. Geothermal power plants operate at high capacity factors (70-100%), with availability factors typically greater than 95%. Geothermal plants are among the cleanest sources of electric power available. Direct use applications directly pipe hot water from geothermal resources to provide heat for industrial processes, crop drying, greenhouses, aquaculture, recreation, sidewalk snow-melting, and buildings. Geothermal district heating systems supply heat to multiple buildings through a network of pipes carrying the hot geothermal water.« less

  • The specific standard of optimum resource conservation is used to evaluate the government's performance in energy regulation in anticipation of new government proposals for a National Energy Plan. Five major areas of government intervention into the energy sector over the past fifty years are examined: percentage depletion allowance tax treatment for oil and gas production, the lsting of intangible drilling costs as expenses, prorationing rules for depth-acreage and well-spacing, import quotas, and price controls on natural gas. The impact of these policies is judged to be counterproductive in terms of resource conservation because of the economics and political pressures ofmore » our system of government, the acceptance of the market failure concept, the compromising nature of the legislative process, the breakdown in the administration of legislation, and the fact that the net costs of the correction exceed the cost of the externality. 12 references.« less
