Day 37: Took Stairs Instead of Elevator
I took the stairs up to my 4th floor apartment instead of using the elevator. Not only does this save energy, but also burns some extra calories as well.
According to CreativeCitizen, “Per floor (one direction, 3 meters): 2.5 Wh. That is approximately 1/2 the amount of energy it takes to recharge a cellphone battery.”
When you think about this on an individual level, the numbers aren’t that much, but if millions of people do this it adds up.
