1 REALISTIC POSSIBILITIES FOR CARBON DIOXIDE NEUTRALIZATION ARE THERE ANY? Christian Breyer 1 and Pasi Vainikka 2 1 Professor for Solar Economy, Lappeenranta University of Technology 2 Principal Scientist at VTT and Adjunct Professor at LUT Nordic Energy Management 2015 Helsinki,

2 Climate Change presents a unique challenge for economics: it is the greatest and widest-ranging market failure ever seen. Nicholas Stern, Economics of Climate Change, 2006

3 / AGENDA new investments in non-renewable energy technologies (except gas) may end as stranded investment existing energy subsidies for non-renewable energy technologies are a major risk for the energy transformation and CO 2 reductions solar and wind are the least cost solutions for energy atmospheric CO 2 can be used as a raw material in the new energy world energy system transformation is part of digitalisation - we are heading towards energy cloud

4 / AGENDA new investments in non-renewable energy technologies (except gas) may end as stranded investment existing energy subsidies for non-renewable energy technologies are a major risk for the energy transformation and CO2 reductions solar and wind are the least cost solutions for energy atmospheric CO 2 can be used as a raw material in the new energy world energy system transformation is part of digitalisation - we are heading towards energy cloud

5 / IMPLICATION As much as 80% of the coal, oil and gas reserves are unburnable, and this unburnable carbon represents potentially stranded assets. Unburnable carbon will be reached in just 16 years if energy consumption continues unfettered.

6 / STRANDED INVESTMENTS Current coal plant fleet is violating climate change targets, every new plant will worsen the situation Investment managers start to put coal companies on their sell lists AND execute it (such as the largest investor globally, the Government Pension Fund of Norway) Source: Carbon Tracker, several reports in 2014 and 2015

7 / AGENDA new investments in non-renewable energy technologies (except gas) may end as stranded investment existing energy subsidies for non-renewable energy technologies are a major risk for the energy transformation and CO 2 reductions solar and wind are the least cost solutions for energy atmospheric CO 2 can be used as a raw material in the new energy world energy system transformation is part of digitalisation - we are heading towards energy cloud

8 / WHAT HAS BEEN PROPOSED? Former Shell chairman Jorma Ollila 20 May 2015: The number one action on global level: The substantial subsidies the fossil fuels enjoy, should be removed. Available in Finnish at: time.: 01h03min10s

9 / HOW BIG ARE THESE SUBSIDIES?

10 / SUBSIDIES: COAL Key insights: Societal extra costs of coal in China are about 150 $/MWhe (key reason for shift to wind and solar PV in China) Societal subsidies in Germany are about 100 $/MWhe (more than total costs of wind and plus costs for coal fuel and plant more than solar PV TODAY) Why do societies accept this financial and health burden? 50 $/MWhe multiply with 10 to get $/MWhe

11 / SUBSIDIES: GERMANY Case of Germany: there are subsidies for RE subsidies for fossil-nuclear are higher nuclear got AND get the highest subsides per kwh of all technologies subsides in total are 649 b (fossil-nuclear) plus 102 b (RE) in total societal costs of RE are lower than those of fossil-nuclear energy source: FÖS, Was Strom wirklich kostet

12 / AGENDA new investments in non-renewable energy technologies (except gas) may end as stranded investment existing energy subsidies for non-renewable energy technologies are a major risk for the energy transformation and CO 2 reductions solar and wind are the least cost solutions for energy atmospheric CO 2 can be used as a raw material in the new energy world energy system transformation is part of digitalisation - we are heading towards energy cloud
