CO2 Saved Formula:
| From: | To: |
The CO2 Saved Per Kwh Solar Calculator estimates the amount of carbon dioxide emissions avoided by using solar energy instead of conventional grid electricity in Australia. It helps quantify the environmental benefits of solar power generation.
The calculator uses the formula:
Where:
Explanation: This calculation is based on the average carbon intensity of the Australian electricity grid, which varies by region but averages approximately 0.8 kg CO2 per kWh.
Details: Calculating CO2 savings from solar energy helps individuals and organizations understand their environmental impact, meet sustainability goals, and contribute to Australia's renewable energy targets and carbon reduction commitments.
Tips: Enter the total solar energy generated in kilowatt-hours (kWh). This value can typically be obtained from your solar monitoring system or electricity bill. The value must be greater than zero.
Q1: Why use 0.8 as the emissions factor?
A: 0.8 kg CO2 per kWh is the average carbon intensity of grid electricity in Australia, though this can vary by state and over time as the energy mix changes.
Q2: How accurate is this calculation?
A: This provides a reasonable estimate based on average grid emissions. Actual savings may vary depending on your specific location and the time of energy generation.
Q3: Does this account for solar panel manufacturing emissions?
A: No, this calculation only considers operational emissions. A full life-cycle analysis would include manufacturing, transportation, and disposal emissions.
Q4: How does solar compare to other renewable sources?
A: Solar typically has lower life-cycle emissions than fossil fuels but may have higher emissions than wind or hydro power in some cases.
Q5: Can I use this for commercial solar installations?
A: Yes, the same calculation applies regardless of system size. Simply enter the total kWh generated by your commercial solar array.
