SURPRISING FACTS FROM YOUR GAS TANK
So, we’ve all gone to the gas station to fill a car up with gasoline — but what happens after that? The engine runs, we get where we’re going and that gasoline burns up, combusts, and just disappears. Right?
Not exactly. There are some really important things to understand about what happens next, and a few of them should surprise all by the nerdiest climate scientists (btw, I’m a fan of nerdy climate scientists).
1. Burning one gallon of gas releases 19.4 lbs. of CO2
You probably know that CO2 is one of the leading causes of warming in the atmosphere. But how does one gallon of gas, which weighs about 6 pounds, create nearly 20 pounds of CO2?
Basically, when gas is burned the carbon it contains mixes with oxygen to create CO2. When it pulls this oxygen out of the atmosphere, you arrive at our next surprising fact:
2. You remove 21 pounds of breathable oxygen for every gallon of gasoline you burn
Burning gasoline also produces water (H2O) and this pulls out even more oxygen from the atmosphere. The total of 21 pounds is pretty impressive given that a person breathes about 450 pounds of oxygen each year. This also reduces air quality for people living next to highways and busy roads, which is a big deal. And finally...
3. By ridesharing for a day you can offset the amount of CO2 a large TV generates in a month
If you’re still reading, you’re probably interested in the numbers on this one, so here they are:
21.29 mpg = Average passenger car fuel efficiency in Sonoma County
18.09 miles = Average commute in Sonoma County (round trip is 36.18 miles)
25.66 lbs. = CO2 created by watching a 28” TV per month (308 lbs. per year)
