  • 1. GET YOUR ENERGY BILL DOWN! A Fresh Look at Residential Energy Efficiency February 2010 Private & Confidential
  • 2. Government recognizes the energy reduction imperative Example: Sonoma County’s ‘Climate Action Plan’ Goal is to reduce greenhouse gas (GHG) emissions 25 percent below 1990 levels by 2015 • All nine Sonoma cities and the County established this goal in 2005 Over 90 percent of electricity and natural gas is used by the County’s approximately 200,000 homes & 30,000 businesses Action plan is for an aggressive efficiency retrofit program – 80% adoption rate 150,000 residential accounts 20,000 commercial accounts Source: McKinsey & Company, yoUtilBill 1 confidential – yoUtilBill llc 2009© - all rights reserved
  • 3. Of course, less consumption lowers emissions; residences are key Emissions in United States By 2020, the residential sector will consume 29% of energy in U.S. • Growth of 0.4% driven by population growth, larger homes, and more electrical devices in homes Residential Transportation Buildings (21%) (32%) Over 28% of energy could be saved with positive economic returns • Energy Savings: If enacted all positive Other NPV changes, could save $41Bn a year Buildings and 360 million tons of CO2 emissions (22%) Industrial • Upfront Investment: $229 Bn incremental (25%) which leads to overall NPV savings of $395 Bn Total in California – 492 Millions Tons of Carbon Emissions The U.S. average annual residential energy bill is $2,000, but it could be $1,200 Source: California Energy Commission, The Economist, yoUtilBill 2 confidential – yoUtilBill llc 2009© - all rights reserved

  • 5. After 30 years, why not more progress?? Even homes built after 1978 have poor energy efficiency • Most homes still have little insulation, low performance windows, leaky duct systems, and inefficient HVAC units • This is despite huge government spending on energy conservation awareness and direct subsidies and grants – and mandates! The answer; good citizenship is a good goal – but homeowner pocket book and market forces are the real motivators • Most citizens espouse responsible ethics and wishful conservation intentions • But the real driver of most homeowner actions is inspired by homeowner economics • BUT NO MARKET-BASED APPROACHES HAVE BEEN DEPLOYED TO DATE TO ALTER CONSUMPTION PATTERNS Source: California Energy Commission, yoUtilBill 4 confidential – yoUtilBill llc 2009© - all rights reserved
  • 6. Problem: Bills are rising, but home prices are down; everyone focused on bottom line PG&E Electricity Prices Greater Bay Area Home Prices Price Dollars per kWh $0.45 $0.40 $0.35 $0.30 Base $0.25 101-130% 131-200% $0.20 201-300% >300% $0.15 $0.10 $0.05 $0.00 Jan-04 Jan-05 Jan-06 Jan-07 Jan-08 Jan-09 Source: PG&E, yoUtilBill 5 confidential – yoUtilBill llc 2009© - all rights reserved
  • 7. Problem: Most homeowners have no idea on home energy consumption economics How should homeowners prioritize energy efficiency actions? Inadequate insulation in attic & walls Leaky ducts Inefficient light bulbs Lack of programmable thermostat Plug load from small appliances Inefficient kitchen appliances Inefficient washer & dryer Inefficient furnaces & water heaters Source: yoUtilBill 6 confidential – yoUtilBill llc 2009© - all rights reserved
  • 8. Problem: The economics are complex Calculating the Economics • Evaluate your current energy usage as well as the prices you pay • Identify all ways to save you energy • Calculate the energy savings of each action • Determine the equipment & installation cost to perform action • Determine the cost to finance each action • Identify all rebates, tax credits, & recycling opportunities Only Actions That Save Money Should Be Performed Source: yoUtilBill 7 confidential – yoUtilBill llc 2009© - all rights reserved
  • 9. If homeowners know what actions will be economically wise, they will respond… Actual example of savings - $2,500 every year Do these Don’t do these Old annual bill: $6,0331 $6,000 $1,292 $5,000 $27 $55 $146 $44 $97 $684 $254 $334 $4,000 $159 $48 $115 $40 Expected new annual bill: $3,4211 $3,000 $2,000 $1,000 $0 Baseline Plug Loads Air Sealing Lighting Attic Insulation Wall Insulation Crawlspace Refrigerator 1 Pool Filter Pump Dishwasher 1 Heat 1 Water Heater 1 Clothes Dryer 1 Clothes Washer 1 Insulation 1Based on cost of energy consumed in last 12 months; under today’s pricing 8 confidential – yoUtilBill llc 2009© - all rights reserved Source: Equipment specifications, customer interviews, yoUtilBill analysis
  • 10. Problem: Most homeowners don’t want to invest, they want flexibility to move in 1 yr Options are emerging that allow homeowners to invest in their home’s energy systems without carrying the liability if they choose to move anytime in the future • California Assembly Bill (AB) 811 enables local governments to offer energy efficiency loans to homeowners – Sonoma County has launched this program with $100m in funds – Improvement projects must be tied to the home (e.g. duct work, windows, boilers) – Loans are payable twice a year through property taxes; 7% now, to 3%? • Utilities are considering on-bill financing for residences – Include loan repayments on monthly bill – Ongoing obligations stay with the meter, not the individual Without the ongoing obligation to pay for improvements after moving house, customers are now inspired to invest as efficient homes have higher valuations Source: yoUtilBill 9 confidential – yoUtilBill llc 2009© - all rights reserved
  • 11. Further, standard private-sector market targeting will deliver the most reductions Home Energy Consumption in Sonoma County Households (Occupied) 40,000 Median 35,000 Average 30,000 25,000 20,000 20% of customers consume 40% of Sonoma’s 15,000 electricity supply 10,000 25% reduction in top quintile consumption gives 10% reduction in county 5,000 0 690 2,070 3,450 4,830 6,210 7,590 8,970 10,350 11,730 13,110 14,490 15,870 17,250 18,630 20,010 21,390 22,770 24,150 25,530 26,910 28,290 29,670 31,050 32,430 33,810 35,190 36,570 Electricity Consumption (mid-point consumption of HHs in range; kWh/Year) Source: UC Berkeley, RECs, EIA, NEIP analysis Source: yoUtilBill 10 confidential – yoUtilBill llc 2009© - all rights reserved
  • 12. Savings opportunity high for large users; Others must be careful with retrofits Group General Traits Usage Retrofit Economics • Many types of retrofit initiative Top 20% - High • Multi-occupant make sense Consumers • Detached dwelling 43% • Very confusing to figure out • Larger square footage what to do • Some types of retrofit make Next 40% - Mid • Mix sense; most are borderline 41% Consumers • Very confusing to figure out what to do • Single-occupant • Few types of retrofit action make Lowest 40% - Low • Multi-unit dwelling sense (e.g. weatherization) 16% Consumers • Smaller square footage • What needs to be done is often very predictable 11 confidential – yoUtilBill llc 2009© - all rights reserved Source: yoUtilBill

  • 16. Will the change happen? Large focus on incentives & stimulus money • $3.2 Billion allocated to fund Energy Efficiency & Conservation Block Grants • $5 Billion in funding for low-income weatherization programs • $800 Million for green jobs, rebates for appliances, & Energy Star Program • Massive subsidization of solar potentially reduces efficiency incentives Financing programs hold great potential, but are in their infancy • Many policy issues need to be addressed – type of assessment, if only finance cash flow positive investments, repairs / replacement • Large potential market for municipal bonds if successful Workforce needs to be developed • Potential for 1.5 million jobs, but need to be adequately trained Consumer awareness about energy efficiency still quite low Source: yoUtilBill 15 confidential – yoUtilBill llc 2009© - all rights reserved
