Urban Solar workshop talk
1) The agenda includes an intro talk, break/discussion, group work, and role play about 3 motivations for thinking about energy: economic, political, and environmental. 2) The intro talk discusses topics like crude oil production decline, oil supply dependence on imports, and how using fossil fuels impacts climate change and the environment. 3) The document proposes solutions like producing lots of renewable electricity to electrify transportation and heating, though achieving high renewable targets would require country-sized facilities and contributions from everyone through large-scale transformations.
Urban Solar workshop talk
- 1. Agenda: 1/ Warm-up 2/ IntroTalk 3/ Break/Discussion 4/ Group Work 5/ Role Play
- 2. 3 motivations tothink about energy! Intro Talk
- 3. Total crude oilproduction 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 undera 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 aLos Angeles gas station in anticipation of rationing, 11 May, 1979 We are interested in security of energy supply! Political motivation
- 6. In 1769 JamesWatt patented his CO2 concentrations (parts/million) for the last 1100 years. steam engine. Using fossil fuels changes the climate! Environmental motivation
- 7. Alberta Athabasca OilSands. 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 networkof 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 canwe do to get off fossil fuels?
- 10. Current consumption perperson 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 estimatesfor 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 adifference, 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 lookingat 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 fromabove!
- 17. The solar potentialof my house:

- 22. So, how mightwe pull this off?

- 24. Taking inspiration fromdispersion 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.”
