## What does this tool do?

The Energy Consumption Calculator is a user-friendly online tool that helps you estimate how much electrical energy your household appliances and devices use in a month. It calculates the energy consumption in kilowatt-hours (kWh), which is the unit used by electricity companies to measure and bill your energy usage.

### Key terms explained:

- Kilowatt-hour (kWh): A unit of energy equal to 1,000 watts used for one hour.
- Wattage: The rate at which an appliance uses energy, measured in watts (W).

## Practical uses for this tool:

- Estimating your monthly electricity bill
- Identifying which appliances use the most energy
- Planning energy-saving strategies
- Calculating the energy impact of new appliances before purchasing
- Educating family members about energy consumption

## How to use the Energy Consumption Calculator:

- Identify the appliance or device (e.g., "Living room TV")
- Enter the number of identical items (e.g., 1)
- Find the wattage, usually listed on the appliance or in its manual (e.g., 100 W)
- Estimate the average hours of use per day (e.g., 4 hours)
- The tool will automatically calculate the monthly kWh
- Repeat for all your major appliances and devices
- View the total estimated monthly energy consumption

## Example calculation:

Let's calculate for a refrigerator:

- Appliance: Refrigerator
- Number of items: 1
- Wattage: 150 W
- Hours per day: 24 (as it runs continuously)
- Result: 108 kWh per month

## Advice and limitations:

- Always use positive numbers for wattage and hours
- Be as accurate as possible with usage times for better estimates
- Remember that actual energy consumption may vary due to factors like appliance efficiency and usage patterns
- This tool provides estimates and should not be used for precise billing calculations
- Some appliances have varying power consumption (e.g., air conditioners), which this simple calculator doesn't account for
- The tool doesn't consider energy pricing tiers or time-of-use rates

You can gain valuable insights into your electricity usage with this tool, helping you make informed decisions about energy conservation and potentially reduce your electricity bills.
