Renewable resources and sustainable resources are related concepts but not exactly the same. Renewable resources are those that can be replenished naturally over time, such as sunlight, wind, and water. Sustainable resources, on the other hand, refer to resources that are managed in a way that meets current needs without compromising the ability of future generations to meet their own needs. While renewable resources are often considered sustainable, not all sustainable resources are necessarily renewable, as some non-renewable resources can be managed in a way that ensures their long-term availability. **
