sort of the human body is pretty inefficient but a 20 mile bicycle ride can burn around 1000 calories while a gallon of fuel contains 31,000 calories.

I am not a chemical engineer so I am not sure how equivalent these two measurements are... I mean for starters I can eat 1000 calories... but I think if I tried to get 1000 calories by consuming gasoline; I would die.

It's almost as if you burn all that fuel to move the car, the content of the car (people) is almost a rounding error.

And generating heat. I believe motorcycles fail to beat bicycles with rereads to efficiency. Though there are significantly better than cars EVs included

That really would be efficient!
But I guess you actually meant to say kilo calories ;-)

[–] Allero@lemmy.today 1 points 1 week ago

This odd shortening of kilocalories to calories drives me mad every time. Like, we just ignore three orders of magnitude, adding massive confusion?

Keep in mind how much CO2 gets emitted for the food you eat during it's production. Being vegan helps.

Of course it's still much between than driving a car, but an ebike would be even better. Even if you charged it with electricity from a coal power plant the CO2 emissions would be way lower

I don't eat more on days I cycle to work than on days that I take the bus or work from home.

[–] Anivia@feddit.org 1 points 1 week ago (2 children)

The calories still have to come from somewhere, even if you may not eat them specifically on the days you cycle

[–] rumschlumpel@feddit.org 1 points 1 week ago

Most people eat more calouries than they need, anyway.

[–] zaphod@sopuli.xyz 1 points 1 week ago

It's called sport, exercise, or do you want to ban that in the name of saving the climate?

[–] commie@lemmy.dbzer0.com 1 points 1 week ago

being vegan would help if it effected production

A moped would be the closest equivalent ~100mpg so 3,000 calories per mile, vs a bike at 50.

I think it's more that the moped /ICE engines are very inefficient then bikes are efficient, as an electric scooter would be lower then both.
