What Does 100 Watts Mean?
Before delving into cost calculations, it’s essential to understand what “watts” mean when it comes to everyday devices. Watts (W) are a measure of power, or the rate at which energy is consumed. A device that uses 100W, like a standard light bulb or a small television, consumes 100 joules of energy every second while it is in operation.
How To Calculate Monthly Energy Consumption
To calculate how much it costs to run a 100W device per month, you need to know:
- How many hours per day the device is used.
- The cost of electricity per kilowatt-hour (kWh) from your utility company.
Here’s a simple formula for calculating energy consumption:
Energy Consumption (kWh) = (Power Rating in Watts × Hours Used) ÷ 1000
This formula converts watts to kilowatts, which is the standard unit for electricity billed by your utility company.
Cost of Energy Calculation
Now, let’s put the data into the cost calculation. Once you compute the energy consumption for the month, you can determine the total cost using the following formula:
Total Cost = Energy Consumption (kWh) × Cost of Electricity (per kWh)
For example, if you use the 100W device for 5 hours a day and your electricity cost is $0.12 per kWh, your monthly cost calculation would look like this:
- Calculate Daily Energy Consumption:
- (100W × 5 hours) ÷ 1000 = 0.5 kWh/day
- Calculate Monthly Energy Consumption:
- 0.5 kWh/day × 30 days = 15 kWh/month
- Calculate Total Monthly Cost:
- 15 kWh × $0.12 = $1.80/month
Thus, operating a 100W device for 5 hours daily would cost you approximately $1.80 per month at a rate of $0.12 per kilowatt-hour.
