Utility customer-supported financing programs are receiving increased attention as a strategy for achieving energy saving goals. Rationales for using utility customer funds to support financing initiatives.

While energy efficiency projects could partly meet new energy demand more cheaply than new supplies, weak economic institutions in developing and transitional economies impede developing and financing energy efficiency retrofits. This book analyzes these difficulties, suggests a 3-part model for projectizing and financing energy efficiency retrofits, and presents thirteen case studies to illustrate the issues and principles involved.

Many state policymakers and utility regulators have established aggressive energy efficiency (EE) savings targets which will necessitate investing billions of dollars in existing buildings - and tax payer and utility bill payer funding is a small fraction of the total investment needed. Given this challenge, some EE program administrators are exploring ways to increase their reliance on financing with the aim of amplifying the impact of limited program monies. While financing is potentially an attractive tool for increasing program leverage and mitigating the rate impacts of utility customer-funded efficiency programs, administrators can face difficult choices between allocating funds to financing or to other approaches designed to overcome a broader set of barriers to consumer investment in EE. Robust assessments of financing's role in reducing energy use in buildings are necessary to help policymakers and program administrators make better choices about how to allocate limited resources to achieve cost effective energy savings at scale. In order to better understand what EE financing can be reasonably expected to achieve, and for whom, this book is organized around three levels of inquiry (Figure 1), from the most fundamental (level 1) to the most detailed (level 3).

Electric and natural gas energy efficiency in the United States is pursued through a diverse mix of policies and programmatic efforts, which support and supplement private investments by individuals and businesses. These efforts include federal and state minimum efficiency standards for electric and gas end-use products; state building energy codes; a national efficiency labelling program (ENERGY STAR®); tax credits; and a broad array of largely incentive-based programs for consumers, funded primarily by electric and natural gas utility customers. This book provides information on projected spending and savings of the future of utility customer-funded energy efficiency programs in the United States; and discusses the shifting landscape of ratepayer-funded energy efficiency in the United States.

This evaluation assesses the performance of IFC s energy efficiency finance program in China aimed at stimulating energy efficiency investments through bank guarantees and technical assistance. The difference made by the program is traced along the chain of interventions: (i) at the level of banks, the program is narrowly based on one of the two partner banks, which, with the help of the program, expanded its energy efficiency lending as a new business line; (ii) at the level of energy management companies, the program s technical assistance improved the program participants access to finance; and (iii) at the end-user level, it promoted the use of energy efficiency investments that achieved reduction of greenhouse gas emissions. The utilization of IFC s program has been rapid compared with other similar programs. The energy efficiency investments supported by the program have reduced greenhouse gas emissions by 14 million CO2 tons per year, slightly in excess of the target set at the beginning of the program. However, there is only a weak differentiation in behavior surrounding energy efficiency investment between end users supported by the program and other similar companies that were not. It is important to note that the performance of the program was heavily influenced by the government s policy actions and the earlier efforts of other players: The Chinese government and other players such as the World Bank. The CHUEE program, relying mainly on commercial funding through IFC s guarantees, builds on these efforts
