How much total â¦ energy a 60 watt light bulb consumes, which is the amount of electricity that has to be paid-for, is measured in wattâ¢hours (that's watts times hours). So a 60 watt bulb consumes 60 wattâ¢hours in one hour, or 60 Wh x 24 hr/day = 1440 Wh per day.That is the same as 1.44 kilowattâ¢hours (kWh), so, if you look up what your electricity supplier charges for 1 kWh you can figure out how much it would cost you in money.o a 60 watt bulb consumes 60 wattâ¢hours in one hour, or 60 Wh x 24 hr/day = 1440 Wh per day.
