Dalle fonti naturali al loro sfruttamento moderno
Viviamo in un mondo sempre più affamato di energia e di risorse naturali che ci consentono di ottenerne in varia forma: fossile, idroelettrica, eolica, solare. Queste risorse però non sono infinite e il loro sfruttamento, oltre ad impoverire il pianeta contribuisce ad inquinarlo. Partendo dal concetto fisico di energia, illustriamo le principali forme di approvvigionamento e sfruttamento che in futuro ci costringeranno a diversificare, puntando sulle fonti rinnovabili e non inquinanti.
