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
There are many factors that go into calculating the energy usage of a light bulb. The wattage printed on the lamp is only the energy use of the lamp when it is new. Depending on the kind of lamp he energy required to run it will increase as it ages. For example a Metal Halide lamp can use up to 50% more power in the last 20% of its life.Another factor is the ballast that may be required to run the lamp. Each ballast has a "ballast factor" which can increase or reduce the overall energy usage of the lamp. Many ballasts have a factor as high as 1.2 which would increase the energy consumption of the lamp to 300 watts.AnswerThe question is asking about energy, not power as per the previous answer. To find the energy consumed by a lamp, or any device come to that, multiply its power rating by the time for which it is used. So a 250-W lamp will use 250 W.h (watt hours) of energy in one hour, 500 W.h in two hours, and so on. Energy is more-commonly expressed in kilowatt hours, for the purpose of billing however, where 250 W.h corresponds to 0.25 kW.h, etcAnswer: In an hour it uses 250 watt-hours. The average bulb probably uses 20-60 watt-hours each hour.

Solar energy is a reusable/inexhaustible resource which means it can be used as much as you want without running out of the resource.
The watt was named after James Watt. The term watt in electric appliances refers the rate at which energy is generated or consumed and therefore is measured in units (e.g. watts) that represent energy per unit time. An example; when a light bulb with a power rating of 100W is turned on for one hour, the energy used is 100 watt hours (The watt second is a unit of energy, equal to the joule).
AnswerApproximately 120,000 TW (terrawatts)That is 120000000000000000 joules per second!More energy hits the Earth from the Sun in one hour that the whole world uses all year.(The world uses 15 terrawatts of power per year.)

One kilo hour equals to one hour. This is used in energy.
kilowatt-hour (kWh)
The first automatic streetlight system was installed in New Milford, Connecticut in 1949. The first traffic light was used in 1914 in Cleveland.
I believe you are thinking of a watt perr hour or more commonly used is a kilo-watt-hour - that's the amount of power used in an hour, not exactly how much work is done however.
It is a unit of energy. If energy is transferred at a rate (power) of one kilowatt, during one hour, then one kilowatt-hour (kilowatt times hour) of energy will be transferred. Since a joule is equal to a watt-second, a kilowatt-hour is the same as 3.6 million joules.
The amount of energy used while sleeping for 1 hour varies based on individual factors such as age, weight, and metabolism. On average, the body can burn around 45-100 calories per hour during sleep, depending on these factors. However, the energy expenditure during sleep is generally lower compared to when awake and active.
It uses 48 watt-hours each hour. In 20 hours and 50 minutes it uses 1 kilowatt-hour or 1 unit of electrical energy, which costs about £0.15
One kilowatt-hour, or KWH.Additional AnswerYou don't 'consume power'; you consume energy. Power is a measure of the rate at which you consume energy.
The unit used to describe the amount of electrical energy provided by an energy source is the kilowatt-hour (kWh). It represents the amount of energy consumed or produced by using 1 kilowatt of power for 1 hour.
watts or kilowatts are used to measure power, which is how quickly energy flows, and electrical energy is measured in kilowatt-hours. A kilowatt-hour is also known as a Unit of electrical energy, and it is the amount of energy used when a power of 1 kilowatt flows for 1 hour.
