This clip from Nobody's Fuel, comes from Section 1: Prisoner's Dilemma -- fossil fuels & what energy means to us. This clips describes the history of renewable energy and how our energy supply changed from 100% renewable in the 1800s to 9% today, comprised mostly of hydro power. An interesting point raised is the switch from biomass (firewood) to stored solar energy (coal) as trees began to become scarce in England and the USA.
