Which of the following statements is true regarding renewable resources?

Renewable resources are characterized by their ability to regenerate naturally over time, making the statement about their regeneration correct. This includes resources such as solar energy, wind energy, and biomass, which can be replenished through natural processes. For example, solar energy harnesses sunlight, which is constantly available, and wind energy relies on atmospheric conditions that are inherently self-replenishing. This ability to regenerate is what distinguishes renewable resources from non-renewable ones, which cannot be replenished within a human timescale.

Other options may present misconceptions about renewable resources; while some can be limited in availability based on geographical location or technology, they generally have a potential for regeneration that is not applicable to non-renewable resources, which are finite. Additionally, while costs can vary, renewable resources often have lower operating costs over time compared to fossil fuels, especially as technology advances. This context emphasizes why the statement about their ability to regenerate is fundamentally accurate.
