Executive Summary

On March 22, 2011, Near Zero invited 64 experts from industry, academia, government and non-governmental organizations to participate in an email discussion of DOE funding priorities, with reference to the Department of Energy (DOE) Quadrennial Technology Review (QTR) Framing Document. As we explained to the expert invitees, “Our goal [was] to provide an efficient and fun way for you to leverage your expertise to advance decision makers’ understanding of important energy issues.” We first asked for answers to the following question: “What are the factors that DOE should consider in allocating RD&D resources among technologies of disparate maturity and potential time to impact?” Our instructions continued, “At this point we are simply asking for factors that should be considered, such as ‘today’s cost per unit output’, or ‘achieved thermodynamic efficiency relative to maximum theoretical thermodynamic efficiency’, ‘social acceptability’, etc.”

Over the course of 24 days, we received more than 30 responses from 15 energy experts. Here, we organize and summarize the responses. A complete transcript of the emails we received is included as Appendix I. The experts discussed factors of materiality, costeffectiveness, and maturity, as well as the necessity of DOE support, potential to reduce energy demand, the effect on U.S. competitiveness and energy security, and technology lock-in. In addition to investment criteria, experts offered general recommendations for improving the informational basis for decisions, the importance of stable and increased funding, and the need to invest in diffusion of what is already known.

Each expert was also invited to address the merits of specific technologies in the context of different factors. Several emphasized the need to reduce demand through efficiency gains at both the device and system levels. In considering the major categories of clean electricity, materiality, maturity and the necessity of DOE funding were common considerations. Cost-effectiveness was also raised several times.
