3 motivations to think
                about energy!




Intro Talk
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
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
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
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
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


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


      Using fossil fuels changes the climate!
        ...and has other serious environmental impacts


Environmental motivation
So what can we do to get
    off fossil fuels?
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.
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)
What about estimates for
      Germany?
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.
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!
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?
My house from above!
The solar potential of my house:

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.”

Urban Solar workshop talk

  • 1. Agenda: 1/ Warm-up 2/ Intro Talk 3/ Break/Discussion 4/ Group Work 5/ Role Play
  • 2. 3 motivations to think about energy! Intro Talk
  • 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 Environmental motivation
  • 8. A complex network of wells, pipelines and roads covers the Kazakh steppe. Using fossil fuels changes the climate! ...and has other serious environmental impacts Environmental motivation
  • 9. So what can we do to get off fossil fuels?
  • 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)
  • 12. What about estimates for Germany?
  • 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?
  • 16. My house from above!
  • 17. The solar potential of my house:

  • 20. Prenzlauer Berg solar potential.
  • 21. Berlin Mitte solar potential.
  • 22. So, how might we pull this off?
  • 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.”
