Assumed these <br />would be replaced: with 70 %. hybrid, 25% electric, 5% <br />hydrogen. <br />For 2035 all fleet vehicles replaced with 40% hybrid, 50 % <br />electric, 10% hydrogen. ' <br />Hybrid assumed to get 35 mpg, electric 85 miles per <br />gallon gasoline equivalent (emissions calculated from <br />electricity use), hydrogen 54 miles per gallon gasoline <br />equivalent; hydrogen assumed produced by electricity,. <br />60.5kWh /kg hydrogen. <br />$3 million annual financing, 40% energy efficiency, 40% <br />solar (remainder is water efficiency —not able to quantify <br />emissions reduction from water efficiency). Energy <br />Efflclency: $0.38 initial cost per annual kWh savings, <br />useful life of 9 years (starting in 2016). Solar: $4.9 /watt <br />capacity, 1,678 kWh annual generation per kW capacity- <br />$2,92/kWh <br />Assumes 1.8 million kWh /yr saved from each year's <br />program installations (a conservative estimate based <br />on existing reduction from SCE Business Direct Install <br />Program), 10 year useful life (starting in 2008).. <br />Reaching 2,905 homes by 2020; 10,375 by 2035. <br />28% Include furnace upgrade; 28% include central <br />AC upgrade; 28% duct sealing; 18% general building <br />envelope Improvements; 24% solar system (avg size <br />5kw).
