I’ve previously worked out money saved in petrol according to Google Maps but discovered that they changed their format. Now I can’t seem to find the bit at the bottom that states how much a journey costs in fuel when you get directions for car travel from A-B. I discovered this when I tried to factor in savings from my park & ride to school project.
Its a 38km round trip driving my usual route to/from work and they calculated that this cost £4.50. Now that the spring mildness is upon us, we’ve already done park & ride 9 times in 2014. This project saves an additional 18km per trip as I ride home from school in the morning and back again in the afternoon to meet the boys and cycle back to the car. I did some searching and found a website that told me petrol cost per km my 1.6 litre Citroën costs (16p).
I can’t be consistent using 2 calculations so now going to use the latter equation for ease of reference. Let me state here, this is a rough calculation and only serves to focus my motivation.
The stats for the 1st quarter of 2014 below:
9 commutes to work
= 342km,£54.72 petrol saved.
9 park & ride to school
= 162km, £25.92 petrol saved.
Brakes service, new tyre, new tube
So thats an example of a net saving of a weeks use of petrol in 3 months right there of ~£40. To further reinforce the point, the money that I have spent on petrol in March so far is £95 which compared to £170 in February is massive. This number is skewed by a whole week of park & ride last week and ferrying Grandma from NZ to from Heathrow and town in February.
Before you ask, no, I’m not measuring how much more we’re spending on food as my extra fuel for this activity. It would be great if I could calculate this from calories burnt so if anyone out there knows of one then I am all for adding that to my obssesion! As I add in extra distances than just the ones stated above, this may complicate things-for example last weeks park & ride morning trip was a 30km countryside plod home. I can only assume that my extra food consumption costs nowhere near the cost of petrol and is keeping our family on the right side of the fuel poverty line…
