It’s plausible that it’s talking about electrical energy (Escalator, Lift etc) rather than physical. Though yeah I get where you’re coming from, would bother me also.
Y’all are taking this sign too literally. It’s pretty common to refer to electricity more generally as “energy.”
3 common words for electricity and the most sensible one is the least used
I think they mean electrical energy
Isn’t it “cal” vs “kcal” (kilocalories), as in 1000cal?
Yes. The “kilogram calorie” is just confidently incorrect shit.
Correct, but more to use kJ (kiloJoule) wich is the right physical unit.
Energy in = energy out.
This means even if you wanted to be environmentally conscious and take the stairs rather than using electrical energy to move the elevator, somewhere there is still energy being spent to create the food that’s giving you that energy, and the electrical grid and elevator can do it at a way higher efficiency than you and the agricultural industry can, especially once multiple passengers are involved.
Kinda true, but not because of the formula. Elevators are really efficient now because of constant innovation. The actual dilemma is that you ‘should’ use elevators if they are already installed, but considering their construction they are way less energy efficient.
I suspect the actual energy cost of going up a few flights of stairs is entirely negligible compared to the subsequent reduction in energy usage for transportation of said human if their weight were reduced.
Except elevators are about 1000 times less efficient than a human body. Please do research before claiming nonsense.
Yeah sign is clear as mud.
