A 60 watt bulb used for 1 hour consumes 0.06 kWh (60 watts * 1 hour / 1000).
2300 watt-hours for every hour it operates. Watts x Hours = watt hours.
A Kilowatt hour is 1000 watts per hour. A 50 watt bulb will use just 50 watts per hour. Therefore over 12 hours the 50 watt bulb will use 50*12 watts = 600 watts or 0.6 of a kilowatt hour.
A 32-watt fluorescent bulb, when used for 1 hour, will consume 0.032 kWh (32 watts รท 1000). The energy consumption can be calculated by multiplying the wattage by the number of hours used.

0.04 kilowatts one kilowatt is 1000 watts
If it is a 40 Watt bulb it converts energy at the rate of 40 Watts as long as it is switched on.
A 32-watt fluorescent bulb, when used for 1 hour, will consume 0.032 kWh (32 watts รท 1000). The energy consumption can be calculated by multiplying the wattage by the number of hours used.
About 90 percent of an incandescent bulb's energy is turned into heat; one watt is 3.41 btu/hr, so 10 watts would be about 3 btu per hour.
Yes, that's the question. A 1000 Watt light uses... 1000 Watts. A 500 Watt light uses, you guessed it... 500 watts. It depends on the size of the bulb. ACTUALLY... Watts are a measure of power, Joules are the measure of energy - you can simply convert watts/hour or watts/second to joules but to say that a 1000 Watt light bulb uses 1000 watts is a ridiculous thing to say =D watts are Wh-1 or Ws-1
A 60 watt light bulb is a light bulb with 60 watts capacity. When talking about watts, you're talking about the power that is transferred from the appliance to the accessories. Therefore, the light bulb labeled "60 watts" takes 60 watts to light up. A 60 watt light bulb will not be as bright as a 120 watt light bulb.
The energy unit is not watts per hour, but watts times hour, simply called watt-hours.One BTU is equal to about 1055 Joules or Watt-seconds; that is about 0.293 watt-hours. Actually there are different definitions of the BTU.The energy unit is not watts per hour, but watts times hour, simply called watt-hours.One BTU is equal to about 1055 Joules or Watt-seconds; that is about 0.293 watt-hours.

Your question is rather like asking, 'How many miles per hour do you do in one hour?' A watt is simply the rate at which you use energy or do work, and it is the same regardless of over what period it is measured.
That bulb is 100 watts or 0.1 kilowatts so it uses 0.1 kilowatt-hour of energy each hour, which costs about £0.015
