3. Total crude oil production from the North Sea, U.S. decline in oil production since 1970. Oil
and oil price in 2006 dollars per barrel. supply today dominated by imports.
Fossil fuels are a finite resource.
Hence, we seek alternative energy sources.
Economic motivation
4. A firefighter under a protective chemical spray at Kuwait’s Greater
Burhan Oil Field, which retreating Iraqi troops had set on fire, 1991
We are interested in security of energy supply!
Political motivation
5. Line-up at a Los Angeles gas station in anticipation of rationing, 11 May, 1979
We are interested in security of energy supply!
Political motivation
6. In 1769 James Watt patented his
CO2 concentrations (parts/million) for the last 1100 years. steam engine.
Using fossil fuels changes the climate!
Environmental motivation
7. Alberta Athabasca Oil Sands. Their production impacts a larger landbase, and
produces more greenhouse gases than conventional methods.
Using fossil fuels changes the climate!
...and has other serious environmental impacts

8. A complex network of wells, pipelines and roads covers the Kazakh steppe.

10. Current consumption per person and a future consumption plan,
in “cartoon Britain 2008” along with a possible breakdown
(left two columns)... of fuels (right two columns).
This plan requires that electricity
supply be increased from 18 to 48
kWh per day per person.
We can produce lots of electricity*
to electrify transportation and heating!
*From renewable sources.
11. The immense
dependence of plan
G on renewables,
especially wind,
creates difficulties
for balancing supply
and demand!
Wind 32 KW/day/person (4x global wind power in 2008 or
120x UK wind power in 2009)
+
Photovoltaics 3 KW/day/person (that’s 6m² of panels per person)
13. Photovoltaics Approx. 9m² of panels per person covering 43% of
all available roofs across the country. (Remaining
real estate is reserved for solar heated water.)
It’s pretty much the same story, only slightly more radical.
14. To make a difference, renewable facilities
have to be country-sized.
What’srequired are BIG contributions by everybody!
Renewable-based energy solution will necessarily be
large and intrusive - Little things wont do!
15. We are looking at large scale
transformations in the material
and institutional infrastructures
that shape the ways in which we
produce and consume energy!
... so what do things look like on the ground?

23. So, how might we pull this off?
One street at a time...
24. Taking inspiration from dispersion processes
of wind turbines?
“Im Bereich der Windenergienutzung, die sich von vornherein
als die kapitalintensivste Form der alternativen Stromproduktion
erwies, entwickelte sich die gemeinschaftliche Handlungsform
„Bürgerkraftwerk“ in der Rechtsform der GmbH & Co KG zu einer
tragenden Säule des Verbreitungsprozesses.”
