| Summary: | Energy efficiency plays and will continue to play an important role in the world to save energy and mitigate greenhouse gas�(GHG) emissions. However, little is known on how much additional capital should be invested to ensure using energy efficiently as it should be, and very little is known which sub-areas, technologies, and countries shall achieve maximum greenhouse gas�emissions mitigation per dollar of investment in energy efficiency worldwide. Analyzing completed and slowly moving energy efficiency projects�by the Global Environment Facility�during 1991-2010, Closing the Gap: GEF Experiences in Global Energy Efficiency evaluates impacts of multi-billion-dollar investments in the world energy efficiency. It covers the following areas: 1.������ Reviewing the world energy efficiency investment and disclosing the global energy efficiency gap�and market barriers�that cause the gap; 2.������ Leveraging private funds with public funds and other resources in energy efficiency investments; using these funds in tangible and intangible asset investments; 3.������ Investment effectiveness in dollars per metric ton of CO2�emissions mitigation in 10 energy efficiency sub-areas; 4.������ Major barriers causing failure and abandonments in energy efficiency investments; 5.������ Quantification of direct and indirect CO2�emissions mitigations inside and outside a project boundary; and 6.������ Classification and estimation of CO2�emissions mitigations from tangible and intangible asset investments. Closing the Gap: GEF Experiences in Global Energy Efficiency can serve as a handbook for policymakers, project investors and managers, and project implementation practitioners in need of benchmarks�in energy efficiency project investments for decision-making. It can also be used by students, researchers and other professionals in universities and research institutions in methodology development for evaluating energy efficiency projects�and programs.
