A refrigerated warehouse at a harbour uses cooling equipment that runs only on electricity. The warehouse would use the same amount of electricity with either supply.
| Electricity supply | Percentage generated using coal | Percentage generated using nuclear fuel |
|---|---|---|
| Current supply | 75% | 25% |
| Proposed supply | 15% | 85% |
Explain why carbon dioxide is released as a result of operating the cooling equipment with the current supply, and where this release occurs.
Predict how the amount of carbon dioxide released each year would change if the proposed supply were used.
