  1. 1. 2009 CERTs Conference February 10, 2009 Accelerating Residential Energy Efficiency:  An Introduction Carl Nelson Center for Energy and Environment
  2. 2. Overview • Sources of residential energy demand • Challenges of achieving residential energy  efficiency • Key drivers for recent resurgence in interest • Characteristics of successful approaches
  3. 3. Residential energy use Source: US DOE EIA 2001 Residential Energy Consumption Study (cold climate dataset) Note: Not including transportation
  4. 4. Challenges in achieving savings in  residential sector • High transaction costs. • Individual consumer behavior plays a large  role in household energy consumption. • Information and logistical barriers to decision‐ making process. • Factors other than economics are primary in  consumer decision‐making. • Financial barriers.
  5. 5. Key drivers in resurgence of interest • Increasing interest in energy/climate issues • Increasing energy costs • Minnesota’s 1.5 percent savings goal
  6. 6. Energy Efficiency:  fastest & cheapest way to achieve carbon  reductions AND create jobs Source: ACEEE 2008 Study of Maryland Energy Efficiency Potential
  7. 7. Minnesota’s 1.5% EE goal • Requires all utilities to run conservation  programs that will reduce demand by 1.5  percent per year (every year) • Applies to both gas and electric utilities • Currently, conservation programs achieve  about 0.6 percent savings, so efforts will need  to more than double • Currently over 90% of savings is in commercial  and industrial sector
  8. 8. Current residential EE efforts vs. state goals:  Electricity 1,600,000 1,400,000 1,200,000 Savings Goals 1,000,000 MWh 800,000 Savings 600,000 Shortfall 400,000 Current Efforts 200,000 0 2005 2006 2007 2008 2009 2010 2011 2012 2013 2014 2015 2016 2017 2018 2019 2020
