  1. Unlocking Energy Efficiency April 22, 2010

  2. We embarked on this project to validate the potential, analyze the barriers inhibiting energy efficiency, and identify solutions that can overcome those barriers Project Background • During our research on GHG abatement, McKinsey encountered the puzzle of energy efficiency.

  3. Project scope and approach Report approach Sponsors of the report • Analyzed stationary uses of energy across residential, commercial, and industrial sectors, including CHP • Examined over 675 efficient end-use measures, but only existing technologies • Focused on productivity; not on conservation (no changes in lifestyle or behavior) • Analyzed NPV-positive applications of energy efficiency; based on incremental capital, operations, and lifetime energy costs – excluded program costs and indirect benefits – discounted at 7 percent • Identified the potential for energy efficiency, the barriers, and potential solutions – no attempt to declare how much potential will be achieved SOURCE: McKinsey analysis

  4. Central Conclusion of our work Energy efficiency offers avast, low-cost energy resourcefor the U.S. economy – but only if the nation can craft a comprehensive and innovative approach to unlock it. Energy efficiency offers avast, low-cost energy resourcefor the U.S. economy – but only if the nation can craft a comprehensive and innovative approach to unlock it. Significant and persistent barriers will need to be addressedat multiple levels to stimulate demand for energy efficiency and manage its delivery across more than 100 million buildings and literally billions of devices. Significant and persistent barriers will need to be addressedat multiple levels to stimulate demand for energy efficiency and manage its delivery across more than 100 million buildings and literally billions of devices. If executed at scale, a holistic approach would yield gross energysavings worth more than $1.2 trillion, well above the $520 billion needed for upfront investment in efficiency measures (not including program costs). If executed at scale, a holistic approach would yield gross energysavings worth more than $1.2 trillion, well above the $520 billion needed for upfront investment in efficiency measures (not including program costs). Such a program is estimated toreduce end-use energy consumption in 2020 by 9.1 quadrillion BTUs, roughly23 percent of projected demand, potentially abating up to 1.1 gigatons of greenhouse gases annually.
