Calculating Average Power Consumption from 1650 KWH/Month

[jpartdq]

Homework Statement

If the average KWH used per month in a household is 1650KWH for the year, what is the average power consumption rate in watts that gives this average KWH energy value?

Homework Equations

KWH X 1000WH/1KWH = W?

The Attempt at a Solution

1650KWH x 1000WH/1kWH = 1.65x10⁶ W

Is this right?

No, KiloWatt-Hour is a unit of energy, Watts are a rate of energy.

1 kilowatt-hour is the number of Joules generated in 1 hour at a rate of 1 kilowatt. With this, you should be able to calculate what rate the question is looking for.

Your calculation is correct. The average power consumption rate would be 1.65 megawatts (MW) per month, or 1,650,000 watts (W) per month. This is a high amount of power consumption and could indicate that the household is using a lot of energy or has inefficient appliances. It would be important to investigate the specific energy usage patterns and make changes to decrease energy consumption and save money on utility bills. Additionally, it is important to consider the environmental impact of such high power consumption and explore ways to reduce it for the benefit of the planet.
