Because of the convenient paradigm of the Kuznets-curve of local pollution.
rich and dirty
Poor and cleanrich and clean!
Time and prosperity
Local pollution

For CO2-intensity we don‘t even have that Kuznets curve so far!

We have to break this correlation, i.e. create a Kuznets Curve of decarbonization.
„rich and carbon free“

And then help poorer countries tunneling through it.

Three methods of decarbonization:
•Less CO2 in energy
•Less energy in wealth
•Less wealth

Conventional thinking suggests:
•80%: Less CO2 in energy
•10%: Less energy in wealth
•10%: Less wealth
100%

… how about „bio-fuels“:
- an ecological
nightmare!
Endless maize fields
Endless palmoil plantations

PV as large as airports? (Saxony, Germany) Wind turbines,- do you want such neighbours?
Hydrodams? Always big conflicts . Geothermal? As deep as the Alps are high…
…how about solar, wind, hydro or geothermal? They are fine in small sizes but can be nasty in large quantities.

Let‘s calculate: if 1b people (the rich) achieve 20% new renewables, that‘s 1/35 of what you would need
for 7b people on earth.
Developing countries
NIC‘s
Old industrial-ized countries
And now imagine a 35fold increase of today‘s biofuels plantations, wind power, hydopower, solar power. It‘s an ecological nightmare!
![Page 26: Prof. Ernst Ulrich von Weizsäcker Co-Chair Moscow Politech Museum 11 May, 2012 Resource Efficiency Can Be the Key to 21st Century Technologies International](https://reader036.vdocuments.net/reader036/viewer/2022070306/55182e0c550346ac318b4f0a/html5/thumbnails/26.jpg)
Avoiding that nightmare could mean:
•30% Less CO2 in energy
•65%: Less energy in wealth
•5%: Less wealth
100% .
That is still a 5 – 10-fold increase of renewables, but at the core it’s a new technological revolution! That’s what we should go for!

I come back to the Green Kondratiev in a moment.
But what can we do for the short-cut for developing countries?
![Page 29: Prof. Ernst Ulrich von Weizsäcker Co-Chair Moscow Politech Museum 11 May, 2012 Resource Efficiency Can Be the Key to 21st Century Technologies International](https://reader036.vdocuments.net/reader036/viewer/2022070306/55182e0c550346ac318b4f0a/html5/thumbnails/29.jpg)
It was proposed by the Indian PM Manmohan Singh. It means the North would have to go shopping for emission rights in the South.
German Chancellor Angela Merkel, on 30.8.07, at the Nikkei Symposium in Tokyo, and later in New Delhi supported the idea!
The best solution is per capita equal CO2 emission rights
![Page 30: Prof. Ernst Ulrich von Weizsäcker Co-Chair Moscow Politech Museum 11 May, 2012 Resource Efficiency Can Be the Key to 21st Century Technologies International](https://reader036.vdocuments.net/reader036/viewer/2022070306/55182e0c550346ac318b4f0a/html5/thumbnails/30.jpg)
This „carbon justice“ approach would make it profitable in developing countries to become very energy efficient and to turn to renewable energies.
Efficiency technology would rapidly migrate to the South. And hundreds of plans for new coal power plants could be scrapped.

Back now to the technology task of decoupling prosperity from CO2 emissions.
Let us think bold about efficiency!

The answer is: One quarter of a kilowatthour!
(knowing that one watt-second is one Joule or one Newton-meter; ¼ kwh is 900.000 watt-seconds)
1 kwh
