External costs in energy pricing, and provide examples.

• A. External costs are impacts not reflected in prices; examples: healthcare costs from pollution, climate damages, ecosystem losses.
• B. External costs are direct production costs only; examples: fuel, labor.
• C. External costs are government subsidies; examples: tax credits.
• D. External costs are profits; examples: dividends.

Answer: (A)

External costs are the impacts of energy production or use that fall on society or other people but aren’t included in the market price. When energy is priced, those social or environmental consequences—like health care costs from pollution, damages from climate change, and losses of ecosystems—aren’t paid for by the energy producer or consumer. Because these costs aren’t reflected in the price, the true social cost of energy is higher than what the market charges. For example, air pollution from burning fossil fuels can lead to respiratory illnesses and higher healthcare costs; climate damages bring about more extreme weather, infrastructure repair, and adaptation costs; and ecosystem losses reduce services like clean water or pollination. The other descriptions mix up what external costs mean: they refer to internal production costs, subsidies, or profits, none of which capture costs imposed on others.
