How much energy does a nightlight consume and how much does it cost to run it all day?
It depends if you use a newer LED, or older incandescent bulb style.
The old bulb style (still popular, and usually cheaper to buy) use about 7 watts.
If you use that for 8 hours, you would use 56 watt-hours. For a year that would be about 20.5 kWh (kilowatt-hour).
An LED style light may be 1/4 watt, which works out to be .73 kWh. per year.
How much that cost depends on where you live, and what rate you pay. 10 cents an kWh is a reasonable approximation for the United States. At that rate, the Bulb light would cost about $2 a year, and the LED would cost 7 cents.
If you leave the light on all the time (in a dark bathroom) triple these numbers. The bulb style would be $6 and the LED about 20 cents. You can see that although the LED light is more expensive up front, it could pay for itself in energy savings in about a year. But neither light will cost that much to run.

NOT MUCH, I would say A penny or less A day.
....a different (cost and environmental) perspective - although the answers above are correct, for small devices using cost always gives answers that seem tiny. For 2 reasons we should get away from this approach: (1) lots and lots of small items add up to a lot; individually they might be small but if that means we ignore all small costs they soon add up. (2) think carbon - 20kWhrs is about 20kg of carbon dioxide (say 45 lb) a year - that's about 13 cubic metres of greenhouse gas just for a nightlight!

How much does hydroelectric energy cost per kw?
The cost of hydroelectric energy production varies greatly depending on factors such as location, size of the project, and construction costs. On average, the cost of producing hydroelectric energy can range from $0.03 to $0.09 per kWh.
How much energy does 60 watt bulb consume if it burns for 28 hours?
To calculate the energy consumed by a 60 watt bulb burning for 28 hours, you can use the formula: Energy (kWh) = Power (kW) × Time (h). Convert the power from watts to kilowatts by dividing by 1000 (60 watts = 0.06 kW). Then multiply by the time in hours (0.06 kW × 28 hours) to get the energy consumed in kilowatt-hours. In this case, the bulb would consume 1.68 kWh of energy.
How much does night light cost?
a nightlight can cost a few dollars depending on the type of nightlight it is such as a bulb or sensor. the decor of the nightlight can be factored in the cost as well.

Can a baby sleep with a nightlight without awakening?
Yes a baby can sleep with a nightlight without awakening. It does, however, depend on how much of a light sleeper the baby is, since all babies are different. But generally, a nightlight should not be a problem as the light is soothing and not blinding like the ceiling lights.

How much energy does incandescent?
Incandescent light bulbs are not energy efficient, as much of the energy they use is converted into heat rather than light. Only about 10% of the energy they consume is actually turned into light.

How much power in watts will an led bulb consume if its energy is 6 joules?
Joules (energy) are not equivalent to Watts (power).If something converts 6 Joules every second, it is 6 Watts. If it takes ten seconds to convert 6 Joules, its power is 0.6 Watts.Multiply the Watts by the seconds to find the Joules.CommentYou do not 'consume' power. Power is simply a rate; you cannot consume a rate! You consume energy; the rate at which you consume it is power.
