I’m thinking of buying a (used) Nissan Leaf to drive around town and have been collecting some facts and figures to see how it compares with other cars here in Japan. I’m leaning heavily towards the leaf for three reasons: it’s cheaper to own/operate, no stopping for gas stations (can charge at home), and I don’t want pump out CO2 (and think about it) every time I drive.

The data below was written with Emacs Orgmode (using it’s fantastic spreadsheet capabilities). As I update my local orgfile, I will also update this page as well and make a small announcement on the blog.

Planning to buy a car soon (probably an EV). Using Org mode to collect my research and the inline spreadsheet mode makes it suuper easy to make tables with formulas in the appropriate cell all with plain text.
