40 W is the power in this case. Whether you have it on a second, or 24 hours, the power will always be 40 W. Now, if it is actually the energy you want to calculate, multiply the power by the time to get the energy. In units:
watts x seconds = joules
or:
kilowatts x hours = kWh
The watt is a unit of power and power is consumed/dissipated instantaneously and continuously. In other words the watts are used now.Power consumed over a period of time is energy. The most common unit of energy used in the electrical field is the kilowatt-hour. But one could also use a unit of watt-year (8.76 kilowatt-hours) or watt-day (0.024 kilowatt-hours) if one wanted to.
0.6kwh x 30 = 18kwh
Eighty-four million barrels of oil are consumed in the world each day as of 2005, a quarter of which is consumed by the U.S.
50 W * (1 kW/1000 W) * (10 hr/day) = 0.5 kW-hr/dayAssuming 30 days/mo.--> 0.5 kw-hr/day*(30 day/month) = 15 kW-hr/month

A normal light bulb will light up in exactly the same way, using exactly the same amount of power and giving exactly the same amount of light whenever you light it. The only difference is, if you light the bulb in a dark place, or at night, it will brighten the dark area. If you light the bulb in an already bright place, or in daylight, it won't change the ambient brightness: it'll just waste power.
The amount of electricity used per day is measured by the watt-hour meter.The electricity consumed depends on the following factors:-Power Factor(p.f) of the load.Amount of load.

Approximately 162,937,222 crepes are consumed each day in Paris, Texas.
we use the light bulb in every day life
all day long it is a measure of power 100 watts is a light bulb 1,000,000 watts is a mega watt used to describe power plants or electrical substation
