Which resource is sometimes unpredictable in terms of energy production due to external factors affecting its social benefits and social costs?

• A. Coal
• B. Solar energy
• C. Nuclear power
• D. Natural gas

Answer: (B)

Verified step by step guidance

1. Identify the key concept in the question: it asks about a resource whose energy production is sometimes unpredictable due to external factors affecting its social benefits and social costs.
2. Recall that social benefits and social costs include not only private costs and benefits but also externalities such as environmental impact, reliability, and variability in supply.
3. Consider each option: Coal, Nuclear power, Natural gas, and Solar energy. Coal, nuclear, and natural gas generally have more stable and controllable energy outputs, though they have other social costs.
4. Solar energy depends heavily on external factors like weather conditions (sunlight availability), which makes its energy production variable and sometimes unpredictable.
5. Therefore, the resource with unpredictable energy production due to external factors affecting social benefits and costs is solar energy.
