+We dedicate this Module to the Mother &

Father of Integral Permaculture: Dana Meadows & Howard Odum, two original

pioneers who helped humanity make great strides in understanding systemic

thinking, in all four quadrants.

What Energy Sources are available & how do they work?Civilizations are based on the fuels they use to power themselves.

The fuel determines the technologies used, and the technologies determine the lifestyles, economies, and eventually the entire culture.

So the transition to sustainable fuels is critical if we wish to design sustainable cultures.

This class explores which fuels can be considered 'renewable' & under which circumstances.

Also we look into the various transformer technologies which are needed to make this energy available to us, how they are most effectively used and we

explore what a truly 'solar-powered civilization' might look like.

“In times of extraordinary

change,

the problem is NOT in achieving all that we could dream,

but in NOT dreaming all that

we could achieve”

(Dee Hock)... things are a lot more interesting than we usually

imagine ...

in the last 20years, the 500 largest firms in the world

increased their production & sales by 700% whilst

REDUCING their labour force

right now are alive 3/4 of the 65+ year olds that

have ever lived. A fundamental problem of

the 21st century.

Jeevon's Paradox

Gravitational

GeoThermal

Solar Energy



In 1865, the English economist William Stanley Jevons observed that technological improvements that increased the efficiency of coal use led to the increased consumption of

coal in a wide range of industries. He argued that, contrary to common intuition, technological improvements could not be

relied upon to reduce fuel consumption.

History has repeatedly shown that energy-efficiency rarely leads to net energy reduction. In fact, quite frequently, efficiency improvements make things worse by actually encouraging a net waste in energy. This counter-intuitive effect is known as the Jevons Paradox.

The end aim is ENERGY

REDUCTION

NOT higher
