Every year, the world uses 35 billion barrels of oil. This massive scale of fossil fuel dependence pollutes the earth, and it won’t last forever. On the other hand, we have abundant sun, water and wind, which are all renewable energy sources. So why don’t we exchange our fossil fuel dependence for an existence based only on renewables? Federico Rosei and Renzo Rosei describe the challenges.

Lesson by Federico Rosei and Renzo Rosei, directed by Giulia Martinelli.
