QUESTION: Which of the following is not a renewable source of energy?
A Sun
B Natural gas
C Wind
D Tidal waves
ANSWER: Natural gas
| Aspect | Renewable sources of energy | Non-renewable sources of energy |
| Availability of source | These sources of energy are naturally replenished. | These sources of energy are finite and depleting. |
| Greenhouse Gas Effect | Helps mitigate climate change | Contributes to climate change |
| Environmental Impact | Low to minimal emissions | High emissions and pollution |
| Energy Security | Less vulnerable | Vulnerable to supply disruptions |
| Sustainability | Sustainable for long term | Finite and unsustainable |
| Cost Trends | Generally decreasing costs | Increasing costs (as reserves deplete) |
| Energy Independence | Promotes independence | Often relies on imports |
| Carbon Emissions | Low to zero emissions | High carbon emissions |
| Pollution effect | Minimal pollution | Significant air and water pollution |
| Health Impact | Low health risks | High health risks (e.g., air pollution) |
| Examples | · Sun
· Wind · Biomass · Tidal waves |
· Coal
· Oil · Natural gas · Nuclear energy |
