First, there is a short story !!! 

Once upon a time…

Long ago, almost all of 

our energy came from 

food (delivering muscle 

power), and almost all 

our energy went into 

securing food for 

ourselves

Dr

Work animal, 

supplementing our 

muscle power and 

enabling larger‐

scale agriculture

Next burn 

wood to run 

boilers, 

trains

Fall 2015

Today, more energy goes 

into growing / harvesting 

food than comes out of 

food!

150 years ago, muscular 

effort and firewood 

provided most of our 

energy.
