Gasoline's Cost in KWH's
Read a interesting piece on the cost to distill gasoline in Kilowatt Hours. Turns out gasoline takes 6 KWH's to distill from crude oil. For example if I get 20 mpg driving at 70 mph this means I am burning 3.5 gallons per 70 miles. Normalized to 100 miles is 3.5 x 1.4285714 = 4.9999999 gallons per 100 miles. Rounding up to 5 gallons (justified here) means it takes 5x6 KWH's = 30 KWH's for me to travel 100 miles in this example. You could compare this directly to BEV and the amount of electricity it would take to drive an electric car the same distance.
When you consider that gasoline has 114,000 BTUs per gallon of energy content then 114,000/3,412 = 33.41 KWH's of energy content plus 6 KWH's to distill. So, your gallon of gas really is worth 39.41 KWH's technically. So if I am using 5 gallons of gas to go 100 miles I am really using 197.05744 KWH's to travel 100 miles in this instance. I am pretty sure if you compare this to any BEV that you will find the amount of electricity needed to go 100 miles is substantially less.
"FOOD FOR THOUGHT" This is just me doing some chicken scratching here. Does anyone have any thoughts on this scenario here? Even a vehicle getting 40 miles per gallon still needs almost 100 KWH's to go 100 miles by this kind of reckoning.
