The German Energy Transition in International Perspective / Rainer Quitzow, Sybille Roehrkasten, Martin Jaenicke. Posdam : IASS, 2016, 40 p. http://www.iass-potsdam.de/sites/default/files/files/iass_study_thegermanenergytransition_ininternationalperspective_en_0.pdf

The study examines the German Energiewende within the context of the global expansion of renewable energy. It underlines the global significance of the German Energiewende, while also making clear that it has been a dynamic interplay of various pioneering countries that has led to the global rise of renewables. The study focuses on the electricity sector, since this is where the most significant expansion of renewable energy is taking place, both in Germany and around the world. As the study shows, the multiple benefits of renewable energy constitute the decisive drivers of a global energy transition. However, given the sharp increase in global energy demand and the negative environmental impacts of the existing energy system, the pace of renewables expansion is not yet sufficient. Important opportunities for social and economic development associated with an increased deployment of renewable energy remain untapped. With its international energy transition policy, Germany is well positioned to make a key contribution to building a sustainable global energy supply system. The study concludes with recommendations on how to further strengthen Germany’s international energy transition policy.

REmap: Roadmap for A Renewable Energy Future. Abu Dhabi : Irena, 2016, 172 p. http://www.irena.org/DocumentDownloads/Publications/IRENA_REmap_2016_edition_report.pdf

Doubling renewables in the global energy mix by 2030 is not only feasible, but cheaper than not doing so. Economic savings would far exceed the costs. It would create more jobs, boost economic growth and save millions of lives annually through reduced air pollution. It would also, when coupled with greater energy efficiency, put the world on track to keep the rise of temperatures within 2°C, in line with the 2015 Paris Agreement. But to meet that goal, renewable energy deployment must happen six times faster than current rates. This second edition of IRENA’s global roadmap provides an in-depth perspective on the energy transition in 40 economies, representing 80% of global energy use. It offers concrete technology options and outlines solutions to accelerate renewable energy growth…

A Tale of Three Markets – Comparing the Renewable Energy Experiences of California, Texas, and Germany / Felix Mormann, Dan Reicher and Victor Hanna. Forthcoming in the Stanford Environmental Law Journal, 45 p. http://ssrn.com/abstract=2743696

The Obama administration has repeatedly identified the large-scale build-out of clean, renewable energy infrastructure as a key priority of the United States. The President’s calls for a cleaner energy economy are often accompanied by references to other industrialized countries such as Germany, hailed by many as a leader in renewable energy deployment. Indeed, the share of renewables in Germany’s electricity generation mix is twice that of the United States, and the ambitious “Energiewende” commits the country to meeting 80% of its electricity needs with renewables by 2050. While some praise the German renewables experience as successful proof of concept, others are concerned with the impact of ramping up renewables on electricity rates, the stability of the electric grid, and the international competitiveness of local industry. The mixed response to Germany’s commitment to solar, wind, and other renewables raises questions as to how much and what, if anything, the United States can learn from Germany’s renewable energy experiment—and vice versa.

Coûts et bénéfices économiques des investissements en matière d’efficacité énergétique dans le secteur résidentiel et immobilier de bureaux en France : Une étude de place – Synthèse des enseignements. Ylios ; Fontier Economics, 2015, 10 p. (projet  financé par la Caisse des Dépôts et Consignations, ENGIE, l’Union Française de l’Electricité et l’ADEME) https://www.frontier-economics.com/es//documents/2016/03/etude-de-place.pdf

L’étude que nous avons menée propose une comparaison de 23 mesures d’efficacité énergétique1 (qu’elles soient actives, passives ou de changement d’équipement), pour un objectif de politique énergétique et écologique donné (5 objectifs politiques ont été retenus : la réduction de la consommation énergétique en énergie primaire, la réduction de la consommation énergétique en énergie finale, la réduction de l’émission de gaz à effet de serre, la réduction de la facture énergétique et la maîtrise de la dépendance énergétique) sur la base du rapport coût-bénéfice de la mesure, le bénéfice étant mesuré en termes de niveau de contribution à l’atteinte de cet objectif…
