Would an All-Electric yaris be cheaper in the long run?

Wow, just for fun..
I ran some numbers..
I converted electricity, food, and fuel into a universal energy amount and then computed the cost of that energy amount for the amount of energy you get..


Electricity ($0.21 a kilowatt hour NY)
1 kWh = $0.21
1 kWh = 3600000 J
1cal=4184 joules
1 kWh = 860 kcal
1000kcal / 860 kcal = 1.16279
1000kcal for $0.24

Food ($1 for a Whopper Jr.)
WhopperJr = 370 kcal
370 kcal for $1.00 (Whopper Jr.)
1000kcal / 370 = 2.7027
1000kcal for $2.70

Fuel ($2.83 a gallon)
1gal = 31mil cals
1gal = 31,000 kcal
1gal = $2.83
1000kcal / 31,000 kcal = 0.032258
1000kcal for $0.09

Conclusion: By FAR, gasoline is still the cheaper way to go here in NY.. Feel free to plug in your own numbers to find out how close electricity gets to fuel costs... Interesting conclusion is that food (even junk food) is very expensive for the small amount of energy you get out of it.

Really puts things in perspective doesn't it.. All those people who consume ridiculous amounts of calories and spend every day in the gym is just wasting tons of precious expensive energy (food)..

Edit:
1 pound of body fat = 3500 kcal
3500kcal / 370kcal (whopper Jrs) = 9.46 Whopper Jrs. in a pound of fat
Value of pound of body fat in food energy = $9.46 per pound of body fat.

Value of pound of body fat if energy is converted into raw electricity
(impossible 100% efficiency assumed): ($0.24)*(3.5) = $0.84

Value of pound of body fat if energy is converted into gasoline (impossible)
($0.09)*(3.5) = $0.32


Can somebody please explain why we're putting the most expensive source of energy (food/ethanol) into gasoline, in order to save gasoline (the cheapest source of energy)?? I don't know, but when you run the numbers it looks like a really dumb thing to do..
