The light bulb uses 1.44 kilowatt-hours of energy over 24 hours.

How many kilowatts are in 1 megawatt?

Answer: 1000 kW

Explanation:

We know,MW = 1,000,000 W.
We know that 1 kW = 1000 W.
To find out how many kilowatts are in a megawatt, we divide the number of watts in a megawatt by the number of watts in a kilowatt:
Calculation: 1,000,000 W / 1000 W/kW = 1000 kW.

How many kilowatts are needed to power a 250-watt computer for 10 hours?

Answer: 2.5 kWh

Calculation: Energy = Power x Time = 0.25 kW x 10 hours = 2.5 kWh.
The computer uses 2.5 kilowatt-hours of energy over 10 hours.

How many kilowatts are produced by a 5000-watt generator?

Answer: 5 kW

Explanation:

Convert the power from watts to kilowatts by dividing by 1000.
Calculation: 5000 W / 1000 = 5 kW.
Therefore, the generator produces 5 kilowatts of power.

10.

How many kilowatts does a 100-watt solar panel generate in 10 hours of sunlight?

Answer: 1 kWh

Explanation:
