Session 1 introduces the physical definition of energy and the essential role of energy in our life, our society and our industrialized economy as illustrated by the worldwide Energy Mix since 1800.
It states that our modern life mobilize way more energy than what our human bodies could, through a fun quiz asking the power of everyday objects (phone, iron, cars, etc.) and insights on how engines work.
Human activities do not "produce" or "consume" energy.
Human activities convert energy from one form to another.
There is a very strong correlation between GDP and the quantity of energy input in the economy.
How much energy does it take to toast a slice of bread? Human body's ability to generate energy is very small compared to our daily 'consumption': how many Roberts do you need?
Massive economic gains have been generated thanks to the quantity of energy mobilized by machines vs. human work and their low-cost compared to the cost of humans.
"Energetic slaves" is a provocative concept developed by Jean-Marc Jancovici to illustrate them well: the individual average energy consumption in rich countries is such that it would require several hundred energetic slaves, had it been produced by human beings.
The 3 major engines are: steam, electric and internal combustion.
Discover how these engines work in motion!
Session 1 alternates between several formats to create a dynamic and interactive course for students: quizzes, videos and lectures.
