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

"The 21st Century Electric Car Tesla Motors." 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.

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 Honda Civic--“EPA-rated at 51 mpg for combined city and highway driving.”2 1 Oremus, Will. "How Green Is a Tesla, Really?"

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 1 "Does The Tesla Model S Electric Car Pollute More Than An SUV?"
