Electricity Vs Combustion The fundamental reasons why the electric car has not attained the popularity it deserves are (1) The failure of the manufacturers to properly educate the general public regarding the wonderful utility of the electric; (2) The failure of [power companies] to make it easy to own and operate the electric by an adequate distribution of charging and boosting stations. The early electrics of limited speed, range and utility produced popular impressions which still exist. ~Electrical World magazine 2009 E SOURCE

Electric Vehicles Are Coming U.S. federal government is promoting them via the broad EV Project Most major auto manufacturers have EV products, prototypes, or R&D Standards are being set as it rolls out Early adopters are already investing Many utilities are independently preparing infrastructure 10
Where Do You Live? Map of planned infrastructure roll-out through EV Project preliminary locations. EV Project Initiative funded via ARRA to roll out 4,700 Nissan Leafs and 11,210 charging stations Pilot cities: Phoenix, Arizona Tucson, Arizona San Diego, California Portland, Oregon Eugene, Oregon Corvallis, Oregon Seattle, Washington Nashville, Tennessee Knoxville, Tennessee Chattanooga, Tennessee 11
EVs Cost More, but Are Cheap to Drive Fuel ($/mile) Chevy Volt (PHEV) $0.03 Nissan Leaf (PEV) $0.03 Cost ~$40,000 (up to $7,500 tax credit) $32,780 (up to $7,500 tax credit) 40-mpg car $0.06 $25,000 Notes: PHEV running 4 miles/kwh and paying $0.12/kWh; 40-mpg car paying $2.50/gallon; tax credit from ARRA. 12
