HOLY FUCK YOUR MATH IS SHITTY!
"The truck burning 14.28 gallons of diesel generates about 145 grams of CO2. [1]"
-that's 145 Kilograms you fuck! And you have not included the return trip of the tanker as has been discussed already, making it 290 Kilograms of CO2!.
"The energy losses for the transmission line (considering it comes from coal) generates about 7 tonnes of CO2. [2]"
-Where the fuck do you get that from?? And it doesn't even make sense with your later comparisons!
"A BMW 5 Series 520i would be able to drive about 915.294 miles with that gasoline. [4] Driving these miles, it would release about 91 metric tonnes of CO2 (in the streets)."
-With 10,000 gallons of gasoline..
10000 * 3.78541 liters per gallon = 37854.1 liters * 7km per liter = 264,978.70 km *163 grams CO2 per km / 1000000 = 43,190 kg of CO2
43,190 kg + 290 kg = 43,480 kg or 43.480 metric tonnes of CO2
You have also forgotten that gasoline/petrol is refined from oil, and that the refining process uses some percentage of energy and releases CO2 and sulfur. I cannot find any info on the refining cost.
So how does that compare with the Tesla?
Lets make it easy by comparing the grams of CO2 produced for each km according to the BMW literature.. 163 grams/km.
From your own citations, the Tesla has a 60kW or 85 kW battery. -I know nothing about charging of batteries, but they are rated at 370km for the 60 and 480km for the 85. The 60kW is less efficient so I will use that.
60/370 = 0.162162 kW per km.
Accounting for transmission loss and charging loss, .162162 / .8 /.9925 = 0.204234461 kW per km if produced at a plant and transmitted (see previous discussions and citations)
So how much CO2 produced? 2.08 lbs per kW according to your source.
2.08 * 0.204234461 = 0.424807679 lbs CO2 per km
BUT WAIT! THERES MORE! lets convert the pounds to kg
0.424807679 lbs * 0.453592 kg per pound = 0.192689365 kg CO2 per km.
OUCH! According to this (which is highly subjective) A Tesla running on coal-powered electricity produces 19% more CO2 than the BMW.
-But to compare apples to apples.. an oil fired plant about matches the BMW.
And of course a Natural Gas fired plant allows the Tesla to net 30% less Co2 emissions.
We wont even get into carbon-free power sources like solar, wind, water, etc!
