Step-by-Step Calculation
- Determine the power consumption of your Alexa device in watts.
- Convert the power consumption from watts to kilowatts (1 kW = 1000 watts).
- Calculate the daily energy consumption in kWh by multiplying the power consumption in kW by the number of hours the device is on.
- Multiply the daily energy consumption by the cost of electricity per kWh in your area to find the daily cost.
- To find the monthly or yearly cost, multiply the daily cost by the number of days in the month or year, respectively.
Example Calculation
Assuming an Echo device consumes 4 watts when idle and is left on for 24 hours a day, and the cost of electricity is $0.12 per kWh:
– Power consumption in kW: 4 watts / 1000 = 0.004 kW
– Daily energy consumption: 0.004 kW * 24 hours = 0.096 kWh
– Daily cost: 0.096 kWh * $0.12/kWh = $0.01152
– Monthly cost (30 days): $0.01152 * 30 = $0.3456
– Yearly cost: $0.01152 * 365 = $4.20
Minimizing the Cost of Running Alexa
