A number of states are beginning to recognize Demand Reduction Induced Price Effects (DRIPE) as a real, quantifiable benefit of energy efficiency and demand response programs. DRIPE is a measurement of the value of demand reductions in terms of the decrease in wholesale energy prices, resulting in lower total expenditures on electricity or natural gas across a given grid. This paper reviews the existing knowledge and experience from select U.S. states regarding DRIPE (including New York and Ohio), and the potential for expanded application of the concept of DRIPE by regulators.

This report is a comprehensive research study of energy efficiency in Northwest residential buildings. It includes a metering study, a single-family report, a manufactured homes report, and a multi-family report. In addition, it includes state-by-state energy use reports, as well as end-use consumption data.

This report helps policymakers understand how electric and natural gas utilities can achieve greater efficiency by establishing numeric energy savings targets and goals for energy efficiency programs.

This guide provides an assessment of various approaches to Marketing & Outreach for home energy efficiency improvements.

This report describes the effects of utility spending on efficiency programs, how those effects could constitute barriers to investment in energy efficiency, and how policy mechanisms can reduce these barriers.
