Exploring Renewable and Nonrenewable Energy Sources

Mr. Smeads discusses renewable and non-renewable energy sources, explaining their definitions, examples, and differences. Renewable resources can regenerate naturally if used sustainably, while non-renewable resources exist in fixed amounts and will deplete. The video emphasizes the importance of consumption rates for sustainability and provides examples of both types of resources. It concludes with a practice question on biomass as a renewable resource.

What is the main objective of learning about renewable and non-renewable resources?

• To understand their chemical properties

• To study their historical usage

• To learn about their geographical locations

• To identify the differences between them
