“If we were to add together the power of all the fuel-fed machines that we rely on to light and heat our homes, transport us, and otherwise keep us in the style to which we have become accustomed, and then compared that total with the amount of power that can be generated by the human body, we would find that each American has over 150 ‘energy slaves’ working for us twenty-four hours a day.”
Richard Heinberg, The Party’s Over, p 31.
