This report describes benefits attributable to state-level energy efficiency programs. Nationwide, state-level energy efficiency programs have targeted all sectors of the economy and have employed a wide range of methods to promote energy efficiency. Standard residential and industrial programs typically identify between 20 to 30% energy savings in homes and plants, respectively. Over a 20 year period of time, an average state that aggressively pursues even a limited array of energy efficiency programs can potentially reduce total state energy use by as much as 20%. Benefit-cost ratios of effective energy efficiency programs typically exceed 3 to 1 and are much higher when non-energy and macroeconomic benefits are included. Indeed, energy efficiency and associated programs and investments can create significant numbers of new jobs and enhance state tax revenues. Several states have incorporated energy efficiency into their economic development programs. It should also be noted that increasing amounts of venture capital are being invested in the energy sector in general and in specific technologies like solar power in particular. Well-designed energy efficiency programs can be expected to help overcome numerous barriers to the market penetration of energy efficient technologies and accelerate the market penetration of the technologies. x

Environmental policy encouraging hazardous waste reduction began in 1976 with an Environmental Protection Agency statement promoting source reduction as the preferred method of hazardous waste management. In 1984, Congress included a policy statement supporting waste reduction in the Hazardous and Solid Waste Amendments (HSWA). However, the cornerstone of HSWA was the land disposal restrictions (LDRs)-a command and control policy prohibiting land disposal of untreated hazardous waste. Consideration of the hazardous waste generation decision in the aggregate would suggest that the price effect resulting from the LDR program and increased hazardous waste management prices in general would lead to source reduction. Although at the firm level there may be interdicting factors, statistical analysis of generation data for Tennessee support this hypothesis. Both the institution of the LDRs and waste management prices have significant negative effects on the level of generation. The analysis, however, reveals the existence of large industry and firm effects, indicating that the response to public policy may exhibit significant variance, especially at the individual generator level.

This paper assesses the contextual, programmatic and decision-making factors that affect the performance of mature municipal solid waste recycling programs. Tobit models were prepared for cities with populations of less than or more than 25 000 to facilitate analysis of recycling performance. Recycling participation rates were found to be higher among cities in both groups that offered more convenient recycling programs and whose residents had a higher mean household income. The larger cities that achieved higher participation rates employed a decision-making process known as 'collaborative learning', imposed sanctions on improper sorting recyclable materials, and had a larger non-minority population. Among smaller cities, higher participation was attained by using variable fee pricing for solid waste collection and by mandating household participation. The study findings suggest that future research should focus on improved ways to characterize and measure the decision-making processes used to make policy changes in order to facilitate analysis of the causal and temporal relationships between decision-making processes and program performance.
