Superquark - Prepararsi al futuro - Season 1 Episode 5 Efficienza energetica

How much energy could be recovered from waste and greater technological efficiency? Very eloquent examples of savings, for example in the insulation of buildings. How much mobile phones and chats consume. How a company can vertically reduce its energy consumption. It is the theme of the new appointment with "Preparing for the future", the Rai Cultura series created and written by Piero Angela and dedicated to the new generations.
