1. What is an Energy Usage Calculator for Australia?

Definition: This calculator estimates the energy consumption in kilowatt-hours (kWh) based on appliance power rating and usage time.

Purpose: It helps Australian households and businesses understand their electricity consumption and estimate power bills.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( E \) — Energy consumption (kWh)
• \( P \) — Power rating of appliance (watts)
• \( t \) — Time of usage (hours)

Explanation: The formula converts watt-hours to kilowatt-hours (kWh), which is the standard unit for electricity billing in Australia.

3. Importance of Energy Calculation

Details: Understanding energy usage helps in budgeting electricity costs, identifying energy-hungry appliances, and making informed decisions about energy efficiency.

4. Using the Calculator

Tips: Enter the appliance's power rating in watts (found on the label) and the number of hours it's used. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How do I find my appliance's power rating?
A: Check the manufacturer's label, specifications, or user manual. Typical ratings: LED bulb (10W), fridge (200W), AC (2000W).

Q2: How does this relate to my electricity bill?
A: Multiply the kWh result by your electricity rate (e.g., $0.25/kWh) to estimate cost.

Q3: What's the average Australian household consumption?
A: About 15-20 kWh per day, but varies by state, household size, and season.

Q4: Can I calculate monthly usage?
A: Yes, either enter total monthly hours or calculate daily usage then multiply by 30.

Q5: Does standby power consumption matter?
A: Yes! Many appliances draw power when off but plugged in. Consider all usage times.
