The video tutorial introduces renewable and non-renewable energy sources, explaining their types and examples. Renewable sources like solar, wind, hydro, biomass, and geothermal energy are sustainable and replenished naturally. Non-renewable sources, such as fossil fuels, take millions of years to form and are being depleted rapidly. The video emphasizes the importance of using renewable energy and concludes with a call to action for viewers to engage further.
