In 2013, the Delaware Department of Natural Resources and Environmental Control (DNREC) commissioned Optimal Energy to estimate how Delaware could potentially reduce electricity, natural gas and unregulated fossil fuel usage. The study focused on savings opportunities in the building sector that could be achieved through the implementation of energy efficiency technologies and practices. Completed in September of 2014, the study assesses the energy efficiency potential in Delaware from 2014 through 2025. Results of the study suggest that significant cost-effective energy efficiency resources could be included in Delaware’s energy resource mix over the next 12 years, representing billions of dollars in net benefits to customers and reducing greenhouse gas emissions by millions of metric tons.
The Delaware Energy Efficiency Potential Study was completed in two phases. The first phase examined Delaware's economic energy efficiency potential. Economic potential includes all savings that are cost-effective, assuming no or limited market barriers.
Phase I: Delaware Economic Energy Efficiency Potential - published May 24, 2013
The second phase of the study refined and enhanced the findings of Phase I to identify the achievable energy efficiency program potential in Delaware. Achievable program potential provides a more accurate estimation of energy efficiency potential as it includes real market barriers and program intervention in the analysis.
Phase II: Study of Energy Efficiency Potential in Delaware - published September 4, 2014.
