So apparently charging your phone in the car eats up your mileage. .03 miles per gallon assuming $2 a gallon.
If you drive a used Jeep that gets 16 mpg and the tank holds 18 gallons and you drive it till empty every week, that’s 288 miles every week driven.
But the 18 gallons a week x 52 weeks in a year = 936 gallons you use in the year, all else constant.
Of the 936 gallons, if what the article is saying is approx. the thing that’s going on, and I only skimmed through it, that’s
.03 miles/gallon x 936 gallons = 28 miles a year wasted the one used Jeep’s end if the driver charges their phone everyday in the car. That’s approximately 2 gallons of gas wasted, or $4.
Spread across the millions of drivers in America alone, that’s millions of gallons of oil and dollars wasted to charge a phone in the car.
Some more math:
They posit that it’s better to charge your phone at home because it costs .06 cents to charge your phone for an hour at home versus 2 cents an hour with gasoline at $2 a gallon.
If you charge your phone for an hour in the car everyday, 30 min commute to work and 30 min commute home, that’s 2 cents x 365 days, assuming you work every day of the week.
2 cents x 365 days = $7.3 a year for charging your phone in the car.
.06 cents x 365 days (assuming you charge your phone for an hour each day at home) = $2.19
That’s roughly a $5 difference. Spread across the rest of North America alone, that’s millions of dollars that could be saved if people just charge their phones at home!
