Question

Which resource is sometimes unpredictable in terms of energy production?

coal
wood
gasoline
natural gas

Answer 1

Among the options listed, **wood** is sometimes considered unpredictable in terms of energy production. This is because the availability and quality of wood can vary based on environmental factors such as weather conditions, forest health, and sustainability practices. Other resources like coal, gasoline, and natural gas tend to have more consistent and predictable production and supply chains.
