After surveying 50 energy experts, the Brattle Group found that energy efficiency improvements could cause electricity consumption in the US to drop by 5 to 15 percent by 2020 (compared to forecast trends). Further, electric peak demand could decrease by 7.5 to 15 percent.

According to Brattle, efficiency improvement will be driven by increasing electricity costs, innovative rate programs, technological advances, and an overall shift in American values and behavior.

Dynamic pricing programs are predicted to gain between 7.5 to 20 percent acceptance among residential consumers, while participation among commercial and industrial consumers could range from 10 to 30 percent.
