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
A 32 watt bulb uses 32 watt-hours, or 0.032 kWh, every hour it is used.
The bulb uses 7.5 watt-hours each hour, or 90 watt-hours if left on for 12 hours. 1 unit of electricity would be used in 11 days at 12 hours per day.
Actually, your wrong. Sure, the lighting ithat is set for proper illumination is 60watts, but if anyone is used to using a dimmer, you can dial down the power consumption for a typical incandescent bulb and it will still light. And as expected, the light level will decrease as you lower the dimmer setting as well.
A kilowatt is 1,000 watts. A 60 watt bulb uses 60 watts in an hour. So, in half an hour it uses 30 watts. Now if a kilowatt costs 20 cents, what does 0.03 kilowatt cost?
Using a 7 watt bulb for 1 hour would cost about 0.84 cents based on the average electricity rate in the United States. Over a year, if used for 4 hours a day, it would cost around $12.25 in electricity.
Wood can not let a light bulb light up because wood is a very poor conductor of electicity. A better conductor would be types of metals such as copper or gold, which is used in many electronics.
A 32 watt bulb uses 32 watt-hours, or 0.032 kWh, every hour it is used.
Water, wind and gas
it also depends on what meter you have, is it a KWH METER or a AH METER. IF ITS A KWH METER(KILO WATT HOUR) IT COUNTS IN WATTS (35w PER HOUR.)
The energy used (work done, same thing) is 120 watt-hours, which is also 0.12 units or 120x3600 joules.
The bulb uses 7.5 watt-hours each hour, or 90 watt-hours if left on for 12 hours. 1 unit of electricity would be used in 11 days at 12 hours per day.

How a dam is used to make electicity The dam holds back water from a river or similar.
Using a 7 watt bulb for 1 hour would cost about 0.84 cents based on the average electricity rate in the United States. Over a year, if used for 4 hours a day, it would cost around $12.25 in electricity.
