Renewable and Non-Renewable Energy Sources

The video discusses renewable and nonrenewable energy sources, focusing on fossil fuels and their formation over millions of years. It highlights the advantages and disadvantages of using carbon-based fuels for energy and as feedstock. The video also explores renewable energy sources like solar, wind, and biofuels, emphasizing their environmental benefits. It concludes with the impact of energy sources on global warming, using the Keeling curve to illustrate rising carbon dioxide levels.

What is the primary reason fossil fuels are considered non-renewable?
