Green power contract
Type kWh, residual g, g after purchase, cover % and mixer. 9000, 380, 50, 100 and 0.85 give 2.5 kg CO₂e · avoided / year. 6000 kWh give 1.4. 12000 kWh give 3.8. Typed grams, not a certificate.

How it works
Green power contract in this calculator is avoided CO₂e from a g/kWh gap. 9000 kWh, 380 g, 50 g, cover 100%, mixer 0.85 give 2.5 kg CO₂e · avoided / year. The second set gives 1.4 kg CO₂e · avoided / year. The third gives 3.8 kg CO₂e · avoided / year.
Δg = max(0, residual − after) × cover% × mixer. kg = kWh × Δg / 1e6. At 9000 and 380 to 50 the second line is Δ g/kWh · 280.5.
2.5 kg CO₂e · avoided / year is not a register entry. 1.4 kg CO₂e · avoided / year is fewer kWh. 3.8 kg CO₂e · avoided / year is 12000 kWh. Optional fields stay empty.
Appliance electricity next door sums kWh. The solar PV calculator counts year-1 MWh. Here Δg stays: 9000 and 380 to 50 stay 2.5 kg CO₂e · avoided / year.
Type 9000, 380, 50, 100 and 0.85. Then Calculate. 2.5 kg CO₂e · avoided / year. 1.4 kg CO₂e · avoided / year. 3.8 kg CO₂e · avoided / year.
The first set gives 2.5 kg CO₂e · avoided / year. The second gives 1.4 kg CO₂e · avoided / year. The third gives 3.8 kg CO₂e · avoided / year. Another g after at 9000 changes 2.5.
Formula
Δg = (residual − after) × cover × mixer. kg = kWh × Δg / 1e6. Suffix · avoided / year.
How to use
- Type 9000 kWh, residual 380 g and 50 g after purchase.
- Add 100% cover and mixer 0.85.
- Click Calculate. The result is 2.5 kg CO₂e · avoided / year.
- 6000 kWh give 1.4. 12000 kWh give 3.8 kg CO₂e · avoided / year.
- Δg / 1e6. Not a Green-e badge.
9000 kWh / Δ 280.5 = 2.5 kg CO₂e · avoided / year
Δg. 9000 kWh and 380 to 50 give 2.5 kg CO₂e · avoided / year. Not Green-e.
- Green
- g after purchase. 50 at 380 stays inside 2.5 kg CO₂e · avoided / year. 30 at 350 gives 3.8.
- power
- kWh in the year. 9000 leave 2.5 kg CO₂e · avoided / year. 12000 leave 3.8.
- contract
- The cover %. 100 at 9000 leaves 2.5 kg CO₂e · avoided / year. 80 at 6000 gives 1.4.
