On May 9, 2011, the IPCC announced (archive)

Close to 80 percent of the world‘s energy supply could be met by renewables by mid-century if backed by the right enabling public policies a new report shows.

In accompanying interviews, IPCC officials said that the obstacles were not scientific or technological, but merely a matter of political will.

Little of the increase was due to ‘traditional’ renewables (hydro and ‘traditional’ biomass, mostly dung), but to solar, wind and non-traditional biomass.

I, for one, was keenly interested in how IPCC got to its potential 80%. Unfortunately, in keeping with execrable IPCC practices, the supporting documents for the Renewables Study were not made available at the time of the original announcement. (Only the Summary for Policy-makers was made available at the time.) This showed one worrying aspect of the announcement. The report was based on 164 ‘scenarios’ and the ‘up to 80%” scenario in the lead sentence of their press release was not representative of their scenarios, but the absolute top end. This sort of press release is not permitted in mining promotions and it remains a mystery to me why it is tolerated in academic press releases or press releases by international institutions.

The underlying report was scheduled for release on June 14 and was released today on schedule. Naturally, I was interested in the provenance of the 80% scenario and in determining precisely what due diligence had been carried out by IPCC to determine the realism of this scenario prior to endorsing it in their press release. I hoped against hope that it would be something more than an IPCC cover version of a Greenpeace study but was disappointed.

The scenarios are in chapter 10 of the Report. authors of the chapter are as follows (mainly German):

CLAs -Manfred Fischedick (Germany) and Roberto Schaeffer (Brazil). Lead Authors: Akintayo Adedoyin (Botswana), Makoto Akai (Japan), Thomas Bruckner (Germany), Leon Clarke (USA), Volker Krey (Austria/Germany), Ilkka Savolainen (Finland), Sven Teske (Germany), Diana Ürge‐Vorsatz (Hungary), Raymond Wright (Jamaica).

The 164 scenarios are referenced to a just-published and paywalled article by two of the Lead Authors (Krey and Clarke, 2011, Climate Policy). Update – Since this article has been relied upon in an IPCC report, it is liberated here.

Chapter 10 isolated four scenarios for more detailed reporting, one of which can be identified with the scenario featured in the IPCC press release. The identification is on the basis of Table 10.3 which shows 77% renewables in 2050 for the ER-2010 scenatio attributed to Teske et al., 2010. (Teske being another Chapter 10 Lead Author. This scenario is described as follows:

Low demand (e.g., due to a significant increase in energy efficiency) is combined with high RE deployment, no employment of CCS and a global nuclear phase-out by 2045 in the third mitigation scenario, Advanced Energy [R]evolution 2010 (Teske et al., 2010) (henceforth ER-2010).

Teske et al 2010 – online here – is cited as follows:

Teske, S., T[homas] Pregger, S[onja] Simon, T[obias] Naegler, W[ina] Graus, and C[hristine] Lins (2010). Energy [R]evolution 2010—a sustainable world energy outlook. Energy Efficiency, doi:10.1007/s12053-010-9098-y.

However, googling the title led me first to a different article with the almost the same

title ‘energy [ r]evolution:A SUSTAINABLE GLOBAL ENERGY OUTLOOK’ online here. This version is a joint publication of Greenpeace and the European Renewable Energy Council, self-described as the ‘umbrella organisation of the European renewable energy industry’. the title page shows:

The preface to the Greenpeace report is by one R.K. Pachauri, who stated:

This edition of Energy [R]evolution Scenarios provides a detailed analysis of the energy efficiency potential and choices in the transport sector. The material presented in this publication provides a useful basis for considering specific policies and developments that would be of value not only to the world but for different countries as they attempt to meet the global challenge confronting them. The work carried out in

the following pages is comprehensive and rigorous, and even those who may not agree with the analysis presented would, perhaps, benefit from a deep study of the underlying assumptions that are linked with specific energy scenarios for the future. Dr. R. K. Pachauri

Returning now to the original lead to the IPCC Press Release on renewables:

Close to 80 percent of the world‘s energy supply could be met by renewables by mid-century if backed by the right enabling public policies a new report shows.

The basis for this claim is a Greenpeace scenario. The Lead Author of the IPCC assessment of the Greenpeace scenario was the same Greenpeace employee who had prepared the Greenpeace scenarios, the introduction to which was written by IPCC chair Pachauri.

The public and policy-makers are starving for independent and authoritative analysis of precisely how much weight can be placed on renewables in the energy future. It expects more from IPCC WG3 than a karaoke version of Greenpeace scenario.

It is totally unacceptable that IPCC should have had a Greenpeace employee as a Lead Author of the critical Chapter 10, that the Greenpeace employee, as an IPCC Lead Author, should (like Michael Mann and Keith Briffa in comparable situations) have been responsible for assessing his own work and that, with such inadequate and non-independent ‘due diligence’, IPCC should have featured the Greenpeace scenario in its press release on renewables.

Everyone in IPCC WG3 should be terminated and, if the institution is to continue, it should be re-structured from scratch.
