The U.S. Department of Energy-sponsored Transportation Energy Futures (TEF) project examines how combining multiple strategies could reduce both GHG emissions and petroleum use by 80%. The project's primary objective was to help inform domestic decisions about transportation energy strategies, priorities, and investments, with an emphasis on previously underexplored opportunities related to energy efficiency and renewable energy in light-duty vehicles, non-light-duty vehicles, fuels, and transportation demand. This PowerPoint provides an overview of the project and its findings.

The ACP and IRIS are developed to establish a world reference for calibrating pyrgeometers with traceability to SI units. The two radiometers are unwindowed with negligible spectral dependence, and traceable to SI units through the temperature scale (ITS-90). The first outdoor comparison between the two designs was held from January 28 to February 8, 2013 at the Physikalisch-Metorologisches Observatorium Davos (PMOD). The difference between the irradiance measured by ACP and that of IRIS was within 1 W/m2. A difference of 5 W/m2 was observed between the irradiance measured by ACP&IRIS and that of the interim World Infrared Standard Group (WISG).

This presentation examines trends in wind plant cost of energy over the last several decades and discusses methods and examples of projections for future cost trends. First, the presentation explores cost trends for wind energy from the 1980s, where there had been an overall downward trend in wind plant energy costs. Underlying factors that influenced these trends, including turbine technology innovation for lower wind speed sites, are explored. Next, the presentation looks at projections for the future development of wind energy costs and discusses a variety of methods for establishing these projections including the use of learning curves, qualitative assessment using expert elicitation, and engineering-based analysis. A comparison of the methods is provided to explore their relative merits. Finally, a brief introduction is provided for the U.S. Department of Energy program-wide shift towards an integrative use of qualitative and quantitative methods for assessing the potential impacts of wind plant technology innovations on reducing the wind plant cost of energy.
