Tesla’s announcement of batteries for power storage caused a lot of turmoil last week. Kartikeya Singh analyses the significance of the product for the power market and sees it as part of a global trend towards energy decentralization.
German renewable energy lobby organization AEE has published another meta-study, this time reviewing the wide range of scientific investigations into power storage. As Craig Morris explains, the main finding is in line with other recent publications – storing excess renewable electricity from the summer for the winter will not be necessary for a while.
On 20 March 2015, a partial solar eclipse will pass over Germany. Craig Morris says the impact will provide a glimpse of a future in which most households not only have solar roofs, but also battery storage.
A recent study commissioned by Agora Energiewende comes to the conclusion that the German Energiewende does not need new electricity storage within the next 20 years. Instead, flexible fossil-fueled power plants and other intermediate options can deliver the needed power and grid stability at a lower price. Matthias Lang sums up the finding of the report.
The German PV industry is going through a time of creative destruction. Paul Hockenos talked to different actors in Germany who all agree that only the most ingenious companies will emerge strengthened from the current crisis.
Last December, the IFEU Institute of Heidelberg co-published a roadmap for the Energiewende. Martin Pehnt, a co-author of this website, helped direct the project. Craig Morris says the ideas are quite practical.
A new study by German think tank Agora Energiewende looks into what solar power with storage would need to cost to be competitive with other optimized growth scenarios. Craig Morris says the findings need to be heeded.
