Which type of energy source can be reused after being exploited?

1. The question turns on whether the source can be replaced after use. 2. Renewable sources are replenished within a short period and can be used again. 3. Wind and solar energy are the standard examples. 4. Non-renewable sources such as fossil fuels cannot be reused once exploited. 5. Combustible describes whether something burns, and synthetic or natural describes origin, so neither answers the question of reuse. _Source: NECTA CSEE 2022 Chemistry 032, Question 1: Multiple Choice Items, item (v)_
