If the current rate of consumption of non-renewable energy resources, such as coal and petroleum, continues, we will run out of these resources in a few decades. What if we shift our dependence on renewable energy resources? In this lesson, Federico Rosei and Renzo Rosei will discuss the practical aspects of using renewable resources as our sole energy source. We use these resources in two main forms: electricity and liquid fuels. The good news is, we have made quiet progress in developing technologies for harnessing energy from readily available resources, such as solar radiations, water, biomass, and wind. However, total dependence on these resources is limited by technological, economical, and political issues. To find novel solutions we will need creativity, innovation, and powerful incentives.
This video satisfies the 4-ESS3-1 requirement of fourth-grade science proficiency.
Students who demonstrate understanding can: 4-ESS3-1. Obtain and combine information to describe that energy and fuels are derived from natural resources and their uses affect the environment.
