Energy Usage Calculator
Estimate the energy consumption and cost of your appliances with this simple calculator. Understanding your energy usage can help you identify opportunities to save money and reduce your environmental footprint.
How it Works:
This calculator takes three main inputs:
- Appliance Power (Watts): This is the power rating of your appliance, usually found on a label or in the user manual. It indicates how much electricity the appliance consumes when it's running.
- Daily Usage (Hours): The average number of hours per day you use the appliance.
- Cost per kWh: Your electricity rate, typically found on your utility bill. This is the price you pay for each kilowatt-hour (kWh) of electricity consumed.
The calculator then uses these values to determine the daily, monthly, and yearly energy consumption in kilowatt-hours (kWh), and the corresponding estimated costs.
e.g., 100 for a TV, 1500 for a microwave, 60 for a light bulb.
e.g., 5 for a TV, 0.5 for a microwave, 8 for a computer.
Check your electricity bill for your local rate.
Understanding Your Results:
The results will show you:
- Daily Energy (kWh): The amount of electricity the appliance uses in one day.
- Monthly Energy (kWh): The estimated electricity usage over a month (assuming 30 days).
- Yearly Energy (kWh): The estimated electricity usage over a year (assuming 365 days).
- Daily Cost: The estimated cost to run the appliance for one day.
- Monthly Cost: The estimated cost to run the appliance for one month.
- Yearly Cost: The estimated cost to run the appliance for one year.
Example Scenario:
Let's say you have a gaming PC that consumes 300 Watts when in use. You use it for an average of 4 hours per day, and your electricity rate is $0.12 per kWh.
- Daily Energy: (300 Watts * 4 Hours) / 1000 = 1.2 kWh
- Daily Cost: 1.2 kWh * $0.12/kWh = $0.144
- Monthly Energy: 1.2 kWh/day * 30 days = 36 kWh
- Monthly Cost: 36 kWh * $0.12/kWh = $4.32
- Yearly Energy: 1.2 kWh/day * 365 days = 438 kWh
- Yearly Cost: 438 kWh * $0.12/kWh = $52.56
This example demonstrates how even seemingly small daily usage can add up over time. Use the calculator above to check your own appliances!
