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
Isn’t it “cal” vs “kcal” (kilocalories), as in 1000cal?
Yes. The “kilogram calorie” is just confidently incorrect shit.
Technically, yeah, 1 kilocalorie (kcal) = 1000 calories (cal), but in a lot of places (e.g. Americuh), we use the "Calorie" (with a capital C) in place of the kilocalorie.
In other words:
1 kilocalorie = 1 Calorie = 1000 calories
(1 kcal = 1 Cal = 1000 cal)
Yes, it is exactly as stupid as it sounds.
That’s why they can’t have nice things
Trust me, I wish we made more sense. It would make my life a hell of a lot easier. Lol.
Not being bothered by stuff like this seems to be one of the reasons people start using terms that are actually wrong instead of just ambiguous. Like 2K to describe QHD.
I will never let that one go.
Wow, at the beginning I thought you were joking
I wish I were joking. Lol.
Correct, but more to use kJ (kiloJoule) wich is the right physical unit.
I think they mean electrical energy
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.
