What is the primary environmental concern associated with nuclear waste management?

Radioactive contamination

Order the environmental impacts of renewable energy sources based on their positive and negative effects

1⃣ Solar: Low carbon emissions, reduces pollution | Land use, manufacturing processes can be harmful

2⃣ Wind: Low carbon emissions, utilizes wind resources | Habitat disruption, noise pollution

3⃣ Hydroelectric: Low carbon emissions, provides water resources | Alters river ecosystems, displacement of communities

What formula is used to calculate carbon footprint reduction?

Σ(EnergyConsumption×EmissionFactor)
