Book Description
Electricity cannot be cost-effectively stored even for short periods of time. Consequently, wholesale electricity prices vary widely across hours of the day with peak prices frequently exceeding off-peak prices by a factor of ten or more. Most analyses of energy-efficiency policies ignore this variation, focusing on total energy savings without regard to when those savings occur. In this paper we demonstrate the importance of this distinction using novel evidence from a rebate program for air conditioners in Southern California. We estimate electricity savings using hourly smart-meter data and show that savings tend to occur during hours when the value of electricity is high. This significantly increases the overall value of the program, especially once we account for the large capacity payments received by generators to guarantee their availability in high-demand hours. We then compare this estimated savings profile with engineering-based estimates for this program as well as a variety of alternative energy-efficiency investments. The results illustrate a surprisingly large amount of variation in economic value across investments.

Book Description
Conventional wisdom suggests that energy efficiency (EE) policies are beneficial because they induce investments that pay for themselves and lead to emissions reductions. However, this belief is primarily based on projections from engineering models. This paper reports on the results of an experimental evaluation of the nation's largest residential EE program conducted on a sample of more than 30,000 households. The findings suggest that the upfront investment costs are about twice the actual energy savings. Further, the model-projected savings are roughly 2.5 times the actual savings. While this might be attributed to the "rebound" effect - when demand for energy end uses increases as a result of greater efficiency - the paper fails to find evidence of significantly higher indoor temperatures at weatherized homes. Even when accounting for the broader societal benefits of energy efficiency investments, the costs still substantially outweigh the benefits; the average rate of return is approximately -9.5% annually.

Book Description
A growing number of policies and programs aim to increase investment in energy efficiency, because conventional wisdom suggests that people fail to take-up these investments even though they have positive private returns and generate environmental benefits. Many explanations for this energy efficiency gap have been put forward but there has been surprisingly little field testing of whether the conventional wisdom is correct. This paper reports on the results of an experimental evaluation of the nation's largest residential energy efficiency program - the Weatherization Assistance Program - conducted on a sample of approximately 30,000 households in Michigan. The findings suggest that the upfront investment costs are about twice the actual energy savings. Further, the model-projected savings are more than three times the actual savings. While this might be attributed to the “rebound” effect - when demand for energy end uses increases as a result of greater efficiency - the paper fails to find evidence of significantly higher indoor temperatures at weatherized homes. Even when accounting for the broader societal benefits derived from emissions reductions, the costs still substantially outweigh the benefits; the average rate of return is approximately -7.8% annually.

Book Description
Energy efficiency Service Sales Supply Chain, Procurement, Distribution Is Energy efficiency dependent on the successful delivery of a current project? How to Secure Energy efficiency? Where do ideas that reach policy makers and planners as proposals for Energy efficiency strengthening and reform actually originate? Will Energy efficiency deliverables need to be tested and, if so, by whom? Defining, designing, creating, and implementing a process to solve a challenge or meet an objective is the most valuable role... In EVERY group, company, organization and department. Unless you are talking a one-time, single-use project, there should be a process. Whether that process is managed and implemented by humans, AI, or a combination of the two, it needs to be designed by someone with a complex enough perspective to ask the right questions. Someone capable of asking the right questions and step back and say, 'What are we really trying to accomplish here? And is there a different way to look at it?' This Self-Assessment empowers people to do just that - whether their title is entrepreneur, manager, consultant, (Vice-)President, CxO etc... - they are the people who rule the future. They are the person who asks the right questions to make Energy efficiency investments work better. This Energy efficiency All-Inclusive Self-Assessment enables You to be that person.

Book Description
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.

Book Description
Investments in energy efficiency improvements are vital to ensure Europe's future as a sustainable, yet prosperous economy. Amid the COVID-19 crisis, however, there is a great risk of losing sight of the benefits of energy efficiency investments by European firms. The EIB Investment Survey (EIBIS) provides a unique source of data that highlights how more investment in energy efficiency is needed. This report examines the quality of firms' building stock, their spending on energy efficiency measures and the factors that influence their decisions regarding that investment. It highlights that both high-quality information and advanced management practices make a crucial difference in the likelihood of investment in energy efficiency. The regulatory framework needs to be supportive, yet also push for higher energy building performance standards, while financing conditions should facilitate timely investment by firms to realise the enormous gains that can be achieved through energy efficiency improvements.

Book Description
Texas, among the fastest growing states in the country, has a significant opportunity to improve its productivity by quadrupling its investments in energy efficiency over the next two decades. This assessment reviews and updates a 2007 study competed by ACEEE and provides a new assessment of the potential for energy efficiency and combined heat and power to reduce current projections of electricity sales by 20 to 30 percent by the year 2030. The net electricity bill savings could be substantial, ranging from $12 to $14 billion over the period 2012 through 2030. At the same time, the cost-effective investments would direct spending within the state that might boost employment by a net of 50,000 to 100,000 jobs.

Book Description
ENERGY EFFICIENCY uses an applied scientific methodology and case studies to demonstrate and support: The need for the U.S. and the world to commit to energy and resource efficiency as the central goal in investing in electric, heat, and cooling infrastructure, the huge economic opportunity for using the inefficiency built into 20th century energy supply systems, especially, electric, to pay for the upgrades, replacements, and new production and distribution systems of the 21st century, the importance of adopting a standard, web-based energy infrastructure investment decision-making and risk management tool that will serve as a communication medium for all stakeholders to evaluate and compare energy infrastructure investment options and manage investment risks, expansions of the U.S. ‘smart’ grid investment to include evaluation and risk management of energy systems infrastructure investments not just electricity operations, the need to adopt a ‘framework’ for utilities, energy service companies, and customers to work together to close business deals, communicate and manage risks, and realize profits.
