1. What is kWh to CO2e Conversion?

Definition: This calculator estimates the carbon dioxide equivalent (CO2e) emissions from electrical energy consumption.

Purpose: It helps individuals and organizations understand the environmental impact of their electricity usage.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( CO2e \) — Carbon dioxide equivalent (kilograms)
• \( E_{kWh} \) — Energy consumption (kilowatt-hours)
• \( EF \) — Emission factor (kg CO2e per kWh)

Explanation: The energy consumption is multiplied by an emission factor that represents the average CO2 emissions per unit of electricity.

3. Importance of CO2e Calculation

Details: Understanding CO2 emissions helps in carbon footprint assessment, sustainability planning, and environmental reporting.

4. Using the Calculator

Tips: Enter your energy consumption in kWh and the emission factor (default 0.233 kg/kWh for UK grid). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is the emission factor?
A: It represents the average CO2 emissions per kWh of electricity generated, varying by country and energy source.

Q2: Why is the UK default 0.233 kg/kWh?
A: This is the UK grid average, including all generation methods (2020-2021 data).

Q3: How do I find my exact emission factor?
A: Check with your electricity provider or national energy statistics for location-specific data.

Q4: Does this include all greenhouse gases?
A: CO2e includes CO2 plus other GHGs converted to equivalent CO2 impact.

Q5: How can I reduce my CO2 emissions?
A: Use less energy, switch to renewable sources, or improve energy efficiency.
