Adopting new energy-efficient technologies and practices is a key for reducing energy consumption while maintaining economic growth. Fortunately, innovators introduce new T&Ps more rapidly than the market can assimilate them. Some have great potential and some have less, so periodic, systematic evaluations of emerging T&Ps serve to identify the best candidates for program development. Comparing findings over time gives additional insights into the efficiency industry's health, allowing investigation of questions like, "Is the conservation well going to run dry?" This analysis, the third in a decade, began with reconnaissance of 200 T&Ps, which were screened to select those which promise to (1) save at least 0.25% nationally when mature and accepted, (2) avoid large "lost opportunities" in new construction, or (3) capture important regional opportunities. The findings are encouraging: there are still many promising technologies and practices that will save large amounts of energy. On the other hand, the number of "pure" technologies that emerged from the screening process was smaller than before. However, this was compensated by increasing numbers of "practices" that reflect new systems views of older issues. Overall, technologies and practices have the potential to make a major impact on future energy use.
