1 km in a fossil fuel car takes about 2 MJ of gasoline
1 km in an electric car takes about 0.6 MJ of electricity
1 km in a Dutch train takes about 0.4 MJ of electricity
1 km on an e-bike takes about 0.03 MJ of electricity

@Sustainable2050 and 1km on a regular bike?
Ca. 275 kcal expenditure for my ca. 12km commute, so ca. 100kJ per km? How much do I eat for that...

Rabbit-hole alert!

@brnrd 100 kJ/km is 0.10 MJ/km

@Sustainable2050 Yikes! Now I need to go ride an e-bike!?!
Can't imagine that's more sustainable than just propelling myself 😜​

@Sustainable2050 More likely I (or Polar HRM) is exaggerating my energy expenditure when self-propelling on a bicycle
(or my math is waaay off).
I hope I am intimate with any of the unit prefixes between micro and giga (anything beyond those is a crap-shoot)
otherwise I'll have to hand in my Ing. title (Dutch, probably at least US non-ivy-league university master equivalent)
