  • Definition of the normative scenario “2000-watt society” In a „2000-watt society“ all energy services together  require  a continuous flux of primary energy of  no more than  2000 watt per capita  (or: TPES* of 60 GJ /year per capita) Present requirement in Europe:  6000 watt per capita   http://en.wikipedia.org/wiki/2000-watt_society* TPES, Total Primary Energy Supply
  • Use of power or of  primary energy* - in the year 2000 (Switzerland) - and in 2050, in the scenario „2000-watt society“   Unit per capita Year 2000 Year 2050 watt 6000 2000 (continuous flux. 1 W = 1 J /sec) tons oil equivalent (toe) 4.5  1.5 x year gigajoule (GJ)  190 60 x year kilowatt hour (kW.h)  53 000 18 000 x year* TPES, Total Primary Energy Supply
  • Why to cap energy use per capita?For a growing world population:1) Non-renewables energies (fossil, atomic) are limited, risky and environmental disruptive2) Renewable energy technologies are not „free“.   Need input of energy, materials, and surface (and much more...)      Can not expand infinitely3) Global distribution of energy and wealth     is strongly unequal and potentially social disruptive 12
  • Why 2000 watt per capita?1) "Biophysical“ argument: 2000 watt pc would be a precautionary limit       to avoid excessive perturbation to biodiversity and to biosphere  (Wolfram Ziegler, 1977; Hans-Peter Dürr 1993)2) Status quo argument: 2300 watt pc is the average flux of primary energy in the world now3) Quality of life indicators show poor correlation      with growing  energy use beyond 2000 watt pc       (Vaclav Smil 2003)  13
  • Outline1. History of the normative scenario  “2000-watt society”1. Examples in Switzerland2. Objections and obstacles1. Summary and conclusions 14
  • 2002:  The Swiss government adopts the 2000-watt normative scenario ”The scenario of a “2000-watt society” serves as a conception, guiding energy and climate protection policy. In the long term, this would require a reduction in greenhouse gas emissions (primarily CO2) to the sustainable level of one tonne per capita, with per-capita energy consumption of 500 watts being derived from fossil fuels and 1500 watts from renewable sources.”  Swiss Government Sustainable Development Strategy 2002 (and 2008 and 2012)  www.deza.admin.ch/ressources/resource_en_23811.pdf

  • 2008: “Energy saving is outIn its new energy strategy the ETH abandons the 2000-watt society” 36
  • Since 2008: Two diverging strategies 1) Government, cantons, towns, institutions, business: “2000-watt society” in 2050. And 1 t CO2 per capita 2) ETH (since 2008): New slogan: “1-t-CO2-society” in 2100-2150. 4000-6000 watt per capita in Switzerland and worldwideMorosini, Torino, 4.11.2011 37
  • 9 objections or obstacles to a 2000-watt society1. “Reduce damage, not energy!” “A limit should be put to risks and damages caused by energy technologies, not to the level of energy use per se. With C-poor technologies, the average use of primary energy can grow at least up to 6000 watt pc for 9 billion humans.” 38
  • 9 objections or obstacles to a 2000-watt society2. “Energy limit, nonsense!” “A world limit of 2000 watt pc could be either: - too low, if environmental friendly technologies are adopted. - too high, if environmental unfriendly technologies are still be used and world population soars.” 39
  • 9 objections or obstacles to a 2000-watt society3. “Horizon 2050 too soon!”“2100 or 2150 more plausible.” 40
  • 9 objections or obstacles to a 2000-watt society4. “More electrification – and energy - necessary!”“Fossil fuels can be phased out only throughmassive electrification (e.g. private transport; heating)Trade-off: more-electricity-for-less-carbon.” 41
  • 9 objections or obstacles to a 2000-watt society5. “Lifestyles, not negotiable!”“For a 2/3 reduction of energy use,more energy efficiency is not enough.Strong restrictions in lifestyle would be necessary.Unacceptable!” 42
  • 9 objections or obstacles to a 2000-watt society6. Rebound effect outmatches efficiency progressHigher efficiency lowers the price of energy services,thus boosts the overall use of energy. 43

  • If alone, efficiency is not the solution.It is the problem http://www.novatlantis.ch/ 47
  • Two strategies for reducing overall energy use1) Efficiency:Doing more with less.  Reform of technologies2) Sufficiency*:Doing less.  Reform of lifestyles*sufficiency / frugality / sobriety 48
  • Change priorities !1) Sufficiency*:Doing less.  Reform of lifestyles2) Efficiency:Doing more with less.  Reform of technologies*sufficiency / frugality / sobriety 49
  • Ecological economist Herman Daly:“Efficiency-first does not give frugality-second –it makes frugality less necessary.Frugality-first gives us efficiency-secondby making it more necessary.” 50

  • 1. History of the normative scenario “2000-watt society”1. Examples in Switzerland2. Objections and obstacles1. Summary and conclusions 66
  • Summary (1/2)1. All technological energy transformations cause environmental costs – not only fossil fuels. No energy technology can expand infinitely. Renewables neither.2. A voluntary boundary around 2000 watt pc stimulates energy parsimony – including parsimony of fossil fuels.3. Only a “2000 watt society” in the industrialized countries can: a) legitimate them to ask for moderation in energy use worldwide b) offer to developing countries a possible model for sustainable energy consumption. 67
  • Summary (2/2)4. Efficiency (“doing more with less”) is ambivalent: - it can lower energy use in saturable sectors (es. heating, cooling, production) - but generally it boosts energy use in the society as a whole and in non saturable sectors (e.g. private transport, consumer goods, leisure travel)5. Sufficiency (“doing less”) is necessary and accessible through: - voluntary moderation (stimulated by mass communication) - incentives, disincentives, prescriptions 68
  • Conclusions1)For the political community:“Sufficiency first”should raise to a priority in the political and cultural arena.2)For the scientific community:Technologists and economists should bemore aware of the limited – or counterproductive - effectof efficiency progress, if this is not accompaniedby a “sufficiency first” policy. 69
