...I have way too much free time. Or global warming is a bunch of crap (I had a sweatshirt on today). Or my math is just way off.
I saw an ad online today for a synthetic motor oil and how much money I could save if I used it. They had a little savings calculator and you had to input some of your vehicles information for it to calculate your savings. One of the entries was for my vehicles (2005 Grand Caravan) miles per gallon rating. The calculator took me to this
government fuel economy web site to find out what the mpg's were. Here's where my question lies. This government web site says my van produces a carbon footprint of 10.2 tons per year of CO2. I repeat! 10.2 tons.
Now lets do some cipherin'. Gas weighs between 5.93 and 6.42 pounds per gallon depending on temperature and blend of gas. Let's assume a round figure of 6.25 pounds per gallon, just for ease of cipherin'. I have a 20 gallon tank on my van. That comes out to 125 pounds per tank. Now lets figure that I fill up 35 times a year. I giving them 35, but I would guess it's probably less.
Are you still with me now Jethro? I can't do this all day.
With me filling up 35 times a year at 125 pounds per fill up, that comes out to 4,375 pounds of gas I use a year. Now divide 4,375 pounds by 2,000 (a ton) and you get 2.19 tons of gas that I put in my vehicle. I repeat. I use 2.19 tons of gas per year.
Now how does the government come up with their figure, 10.2 tons of CO2 produced by my van per year? It's impossible, it's illogical, it just does not compute!
It's like me saying that if I burn 25 pounds of wood in our fireplace I'll end up with 75 pounds of ash, soot and smoke. That don't make no sense!!!!!
I asked my daughter, she's almost 13 so I thought she'd know, how they came up with 10.2 tons per year. All she could think of was, "it's magical". She's probably right.
