M Messenger, CEC Emerging Energy Efficiency Technologies: Will the new Millenium bring a new wave of energy efficient technologies ? Prepared by b b Michael Messenger b b California Energy Commission b b AP2 Forum on Energy Efficiency b b San Francisco b b May 31, 2000

M Messenger, CEC Background on the Energy Efficiency Situation in California b Four major investor owned utilities develop and administer $250 million in programs designed to save electricity and natural gas; State continually updating building standards b Program administrators oversee roughly $10 million in market characterization, assessment and program evaluation work performed by independent consultants b This presentation will discuss factors leading to success for emerging technology, look at past record of forecasting success and provide a list of emerging technologies for the future.

The Search For emerging Technologies in California

M Messenger, CEC Definition of Emerging Energy efficient Technologies b Less than 2% current market share, potential to reach 20% in 20 years. b Large market where energy savings potential is significant- b Product can be differentiated b Likely to be cost effective and or accepted by installation infrastructure at todays prices over next two decades

M Messenger, CEC Factors to consider in selecting future technology winners b How will savings or other benefits be experienced by customers/owners b Delivery channels and infrastructure b Barriers to new product entry b Easy to incorporate in product specs, guidelines or standards b Future energy markets

M Messenger, CEC Review of Past Track Record in Forecasting Emerging Techs Review of Past Track Record in Forecasting Emerging Techs b ACEEE/CA study predictions from 1992 b Of 20 high priority ETs in 1992 only 5 have been commercialized or incorporated into codes or standards b Most common failure: energy savings overstated or mkt did not materialize
