24. World Oil Consumption TOP WORLD OIL CONSUMERS, 2008 US Source: BP, plc

25. The United States of America depends heavily on imported oil from hostile regions of the world. 50% of our oil use is imported.

26. These hostile states, insurgents and terrorists will use oil as a strategic weapon against the United States.

27. This dangerous dependence on imported oil has created significant issues of: • National Security • Economic Stability

28. Issues of National Security • Dependence on imported oil, mostly from hostile regions, has constrained the totality of US foreign policy. • To ensure free flow of oil, the US military has to maintain a presence in these hostile regions, at a huge cost in treasure and blood. Total cost of US military presence in these regions is estimated to be $5.0 trillion since the 1970’s.

29. Issue of Economic Security • The cost of imported oil is more than $400 billion a year which is enriching the sovereign funds of mostly hostile regimes. This is more than half of the total US trade deficit.

30. US Oil Dependence: Economic Costs HOUSEHOLD GASOLINE EXPENDITURES (ANNUAL, NOMINAL)

31. Oil Dependence • 70% of oil consumed in the US is to fuel our transportation system (the internal combustion engine). • Renewable sources of energy, such as solar, wind or nuclear will not free us from imported oil.

32. The Problem: Oil Dependence • As long as our cars are powered by the internal combustion engine, we will be dependent on imported oil.

33. The Solution: Electric Cars • The only practical and proven solution is to replace the internal combustion engine with an electric motor driven by a rechargeable battery.

34. Electrification of Transportation ELECTRIFICATION ARCHITECTURE

35. Benefits of Electric Cars • Electricity is diverse and domestic.

36. Benefits of Electric Cars • Electric Power Sector: Generation The electric power sector has substantial spare capacity at night that could be used to fuel electric vehicles. LOAD SHAPE FOR ONE DAY DURING PEAK SEASON Source: Pacific Northwest National Laboratory

37. Benefits of Electric Cars • The network of infrastructure already exists.

38. Benefits of Electric Cars • Electric miles are cheaper than gasoline miles: • 2.5¢ vs 10¢ per mile.

39. Benefits of Electric Cars • Electric miles are cleaner than gasoline.

40. Key Enabling Technology – Li-ion Batteries:

41. Lithium ion batteries for mobile phones, laptops, portable electronics and power tools are fully developed and commercialized. This is Proven Technology
