  1. America’s Energy Challenges Steven E. Koonin Under Secretary for Science US Department of Energy June 2011 http://www.energy.gov/QTR

  2. Estimated U.S. Energy Use in 2009: ~94.6 Quads https://flowcharts.llnl.gov/

  3. Energy Essentials Supply • Fewer, long-lived centralized facilities with distribution networks • Change has required decades • Power and fuels are commodities with thin margins • Markets with government regulation and distortion • Technology alone does not a transformation make • Transport and Stationary are disjoint • Transport is powered by oil • Power • Requires boiling large amounts of water • Sized for extremes (storage is difficult) • Numerous sources with differing… • CapEx and OpEx • Emissions • Base/Peak/Intermittency As a whole, energy is • A big and expensive system • In private hands • Governed by economics, modulated by government policies Demand • Many distributed players, shorter-lived assets • User benefit (economics, convenience, personal preference) • Determined by price, standards, behavior • Little attention to system optimization for stationary use

  42. DOE-QTR Scope The DOE-QTR will provide a context and robust framework for the Department’s energy programs, as well as principles by which to establish multiyear programs plans and budgets. It will also offer high-level views of the technical status and potential of various energy technologies. The primary focus of the DOE-QTR process and document will be on the following: • Framing the energy challenges • A discussion of the roles of government, industry, national laboratories, and universities in energy system transformation • Summary roadmaps for advancing key energy technologies, systems, and sectors • Principles by which the Department can judge the priority of various technology efforts • A discussion of support for demonstration projects • The connections of energy technology innovation to energy policy http://www.energy.gov/QTR
