This book seeks to provide policymakers and other stakeholders with actionable information towards a road map for reducing energy consumption cost-effectively. A focus on individual end use equipment types (hereafter referred to as appliance groups) that might be the subject of policies - such as labels, energy performance standards, and incentives - to affect market transformation in the short term, and on high-efficiency technology options that are available today is examined. There is a strong, profit-based business case for investing in more energy-efficient products and designs. Energy efficiency, however, often is viewed as something that businesses and individuals "should" do as good citizens. The reality is that using energy inefficiently is like walking past money on the ground - money that could be put to far better use than paying electricity bills. Investing in energy efficiency therefore creates economic value. This book provides an overview of business case scenarios for energy efficiency in the United States, China and India.
