”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.”

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

Outline

1. History of the normative scenario “2000-watt society”

1. Examples in Switzerland

2. Objections and obstacles

1. Summary and conclusions

28

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 now

3) Quality of life indicators show poor correlation with growing energy use beyond 2000 watt pc (Vaclav Smil 2003)

29

-Swiss government, (Sustainable development strategy 2002, 2008, 2012)

-Zurich population: in a town referendum 78% of the voting population of Zurich decide to write in the town constitution the commitment to a “2000-watt society”

-Some cantons and towns, in their energy strategies

-All major national scientific institutions: ETH, EPFL, EMPA, WSL, PSI

-Society of engineers and architects (SIA), with guidelines for “2000-watt society buildings”

-Zurich, Basel, Geneva: Pilot towns for a “2000-watt society”

2000-2010: The vision of a 2000-watt society

spreads in Switzerland and is adopted by:

2008: “Energy saving is out In its new energy strategy the ETH abandons the 2000-watt society”

Morosini, Torino, 4.11.2011 38

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 worldwide

39

9 objections or obstacles to a 2000-watt society

1. “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.”

40

2. “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.”

9 objections or obstacles to a 2000-watt society

41

3. “Horizon 2050 too soon!”

“2100 or 2150 more plausible.”

9 objections or obstacles to a 2000-watt society

42

4. “More electrification – and energy - necessary!”

“Fossil fuels can be phased out only through massive electrification (e.g. private transport; heating)

Trade-off: more-electricity-for-less-carbon.”

9 objections or obstacles to a 2000-watt society

43

5. “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!”

9 objections or obstacles to a 2000-watt society

44

6. Rebound effect outmatches efficiency progress

Higher efficiency lowers the price of energy services,thus boosts the overall use of energy.

9 objections or obstacles to a 2000-watt society

45

Two strategies for reducing overall energy use

1) Efficiency:Doing more with less. Reform of technologies

2) Sufficiency*:Doing less. Reform of lifestyles

*sufficiency / frugality / sobriety

46

Change priorities !

1) Sufficiency*:Doing less. Reform of lifestyles

2) Efficiency:Doing more with less. Reform of technologies

*sufficiency / frugality / sobriety

47

Ecological economist Herman Daly:

“Efficiency-first does not give frugality-second – it makes frugality less necessary.

Frugality-first gives us efficiency-second by making it more necessary.”

48

Examples of collective sufficiency:

- building all trains for no more than 200 km/h- building all cars for no more than 120 km/h

7. Impossible to forecast new inventions.

“Invention is the mother of necessity” Thorstein Veblen 1857-1929

9 objections or obstacles to a 2000-watt society

50

8. Advertising:

Advertising pressure soars (ca. 1000 billion U$ in 2004)

Desires engineers outperform efficiency engineers.

9 objections or obstacles to a 2000-watt society

51

9. Emulative consumption and growing wealth disparities

The “conspicuous consumption “ of the upper classesstimulates the emulative consumption of the lower classes.

(s. Thorstein Veblen 1857-1929)

52

53

Hervè Kempf (Paris newspaper Le Monde): Restrictions of the material consumption of the upper classes are necessary in order to slow down the growth of the demand by the entire population.

The energy consumption window today (left) and in 2050 (right). The upper, ecological boundary (between 2 and 4 kW/capita) refers to the global average.The lower boundary (600 W/capita) refers to the poorest decile of the global society in 2050.

2. Objections and obstacles

1. Summary and conclusions

60

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 worldwideb) offer to developing countries a possible model for sustainable

energy consumption.

61

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

62

Conclusions

1)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 be more aware of the limited – or counterproductive - effect of efficiency progress, if this is not accompanied by a “sufficiency first” policy.
