Stéphane POUFFARY of ENERGIES 2050 participated in this work as an Expert-Reviewer (team of international experts in charge of providing comments on the two interim versions of the report in February and August 2010).

Vignette - Rapport GIEC Energies renouvelables 2011

Publication of the Intergovernmental Panel on Climate Change (IPCC) ‘Special Report on Renewable Energy Sources and Climate Change Mitigation (SRREN) * Special Report on Renewable Energy Sources and Climate Change Mitigation *

A report of more than 1000 pages and a summary for decision-makers without any ambiguity about the considerable potential of renewable energies that could cover 80% of the world’s energy supply by 2050 provided that appropriate public policies are put in place .

This report will be incorporated into a larger work of the IPCC in the preparation of its fifth Assessment Report. The latter’s synthesis report is expected to be finalized in September 2014. The SRREN Report, approved by the representatives of 194 Governments, analyzes the current market penetration of six renewable energy sources and their deployment potential over the decades.

The six renewable energy sources are:

• Bioenergy: covers energy crops, forest residues, agriculture and livestock, and so-called second-generation biofuels;

• Direct solar energy: particularly solar photovoltaic and solar thermodynamic (concentrated solar power);

• Geothermal energy: based on the extraction of heat stored in the depths of the Earth;

• Hydroelectric power: includes power station or run-of-river projects and reservoir dams;

• Marine energy: from dams to technologies using marine currents or thermal energy from the seas;

• Wind energy: land and marine.

More than 160 scientific scenarios on the market penetration potential of renewable energy by 2050 have been studied, together with their environmental and social implications; four of them were thoroughly analyzed. The four scenarios selected are representative of all technologies.

The objective was to examine possible future worlds, to analyze other paths of socio-economic development and technological evolution.

The researchers also studied the difficulties associated with the integration of renewable energies into existing and future energy systems, including the supply of distribution networks, as well as the potential benefits and costs associated with such an evolution. Download the report

(*) The Intergovernmental Panel on Climate Change (IPCC) is a leading international body responsible for assessing climate change. It was established in 1988 by the United Nations Environment Program (UNEP) and the World Meteorological Organization (WMO) with the task of reviewing and evaluating the most recent scientific, technical and socio-economic data published in the world, useful for understanding climate change. He is not in charge of conducting research or monitoring the evolution of climatological data. The United Nations General Assembly endorsed the joint establishment of the IPCC by WMO and UNEP. The IPCC Plenary is open to all Members of the United Nations and WMO. 194 countries are currently members of the IPCC.
