I was doing my commute on the Tube and thought - how many watts does a single carriage need for lighting?
The Central Line. Each carriage is lit by 12x 36w large flurocent lights and 24 smaller flurocent lights which I shall assume use 25w each.
Doing the math, a single Central Line tube carriage uses 1032w watts of electricity just for lighting. Each Central Line train has 8 carriages meaning each train uses 8256 watts of electricity just for lighting!
The Central Line has 85 x 8-car trainsets. Assuming 75 of them are in service at a given time, 619,200 (Six-hundred nineteen-thousand, two-hundred) watts of electricity is consumed on lighting alone - add the power consumption of the trains' motors and we get an astronomical sum! Then comes the stations, the other tube lines, and the world's railway network...if the Central Line is the tip of the iceberg for railways, what about other uses of electricity?
The railway itself is the tip of the iceberg for a myriad of electricity uses today! It is amazing how much energy humans consume.
