Energy Consumption Formula:
From: | To: |
Definition: This calculator converts power in kilowatts (kW) to energy consumption in kilowatt-hours (kWh) over one year.
Purpose: It helps estimate annual energy usage for electrical devices, systems, or facilities that operate continuously.
The calculator uses the formula:
Where:
Explanation: The power in kW is multiplied by the total hours in a year to calculate total energy consumption.
Details: Accurate energy estimation helps in budgeting electricity costs, sizing renewable energy systems, and assessing environmental impact.
Tips: Enter the power consumption in kW. The calculator assumes continuous operation (24/7) for the entire year.
Q1: Why 8760 hours?
A: There are 8760 hours in a non-leap year (365 days × 24 hours).
Q2: What if my device isn't running 24/7?
A: Multiply the result by your actual operating hours percentage (e.g., 50% runtime = multiply by 0.5).
Q3: How accurate is this calculation?
A: It provides a theoretical maximum. Actual consumption may vary based on usage patterns and efficiency.
Q4: Can I use this for solar panel calculations?
A: Yes, to estimate annual production, but account for capacity factors (typically 15-25% of rated power).
Q5: How do I convert the result to cost?
A: Multiply kWh by your electricity rate (e.g., $0.12/kWh × result = annual cost).
