7 Conclusion

Despite increasing gains, energy efficiency (EE) in general, and demand-side energy efficiency (DSEE) measures in particular, remain underutilized within the options that comprise the clean energy portfolio. In Asia and around the world, EE's potential to cost effectively meet long-term energy demand, while reducing environmental and climate threats, demands greater action from both the public and private sectors.

This report has reviewed current lessons from EE implementation to date, in attempting to clarify the barriers that often impede otherwise economically profitable and technically feasible action, and the strategies that may be deployed to overcome them. ADB, already a leading regional player in facilitating clean energy and DSEE investment among its developing member countries (DMCs), seeks possibilities for even more ambitious action. Conceptual and practical approaches for scaled-up DSEE investment in the region are now needed, and proposals for enhanced institutional expertise, knowledge management, and capacity building and coordination are steps in that direction.

Through efforts that blend lessons from existing global best practice, with attention to current policy and market conditions in Asia, ADB stands ready to accelerate the pace of DSEE in meeting needs within its DMCs. The potential gains of this transformation are significant and compelling but will require consistency of purpose and willingness to engage change as necessary. A perspective that extends beyond capture of the "lowest hanging fruit," and movement toward systematic and coordinated action within and across sectors, can allow DSEE to achieve its appropriate place as a leading solution to global and regional energy challenges.
