1. Fuel efficiency and CO2 emissions of Tesla cars vs regular automobiles By: Greg Gershkowitz, Katarina Pokrajac, Nathaniel O Halla http://123hdwallpapers.com/car-tesla-s-night-lights.html

2. How Tesla Cars Work - The motor converts electricity into mechanical power and also acts as a generator, turning mechanical power into electricity. When the accelerator pedal is released, the motor switches to generator mode and captures energy while slowing the car. - "The 21st Century Electric Car Tesla Motors." http://www.evworld.com/library/Tesla_21centuryEV.pdf

3. Fuel efficiency compared to normal cars - Equivalent of 87 miles per gallon1 - Up to 265 miles on single battery charge1 - 85 kilowatt battery1 - Equivalent of less than 3 gallons of gas1 - At best, only 30% of the energy stored in gasoline is converted to forward motion. The rest is wasted as heat and noise.2 1 Oremus, Will. "How Green Is a Tesla, Really?" Technology: Innovation, The Internet, Gadgets, and More. TheSlateGroup, 9 Sept. 2013.

7. Why use tesla Cars - Consumer Reports rating of 103/100 for Model S P85D2 - The more you drive it, the greener it becomes. 3 - electricity costs about $0.06 for one kilowatt hour (kWh). To charge a car like the Nissan Leaf, with a 24 kWh battery, it would cost $1.44 to go 100 miles1 - To go 100 miles in an internal combustion car, like the Nissan Altima, it would cost about $14.25 in gasoline.1 2 "Tesla Model S P85D."

8. Cons of Teslas - Battery requires charging1 - Very pricey - The cost of a Tesla Model S can range from $70,000 to $138,0001 - Charging inefficiency - The "peak charging efficiency" of Tesla cars is 92%3 - Vampire losses2 Energy wasted when the car is off2 1 Model S."
