At the end of September, the heads of states met in New York for a climate summit to pledge action on climate change. While renewables were not at the center of attention, Anna Leidreiter argues that future commitments need to contain a pledge to transition to 100% renewable energy by 2050. A growing number of cities, regions and even countries around the world have already proven that such a path is realistic.

What solar grid integration costs
The price of solar has plummeted in recent years, but as the share of solar on the grid increases, associated costs will be incurred: idling backup capacity, forecasting errors, etc. Now, leading US researchers have tried to put a price tag on those costs. Craig Morris says the situation they describe for 2027 looks a bit like Germany today.
What’s happening with biomass in Germany?
Biomass is the largest source of renewable energy in Germany, but the German government has scaled back support in recent years. Under the amendments to the German Renewable Energy Act to become law in August, support would be reduced even further. Craig Morris investigates.
Re-Municipalization in Boulder and Hamburg: Similarities and Differences
Both Boulder and Hamburg are remunicipalizing their grid. What do the two cases have in common? How far did the specific national context help or impede the efforts to buy back the grid? In the final part of our series, Charleen Fei and Ian Rinehart compare the two cities and the conditions for their success.
The Fight for the Grid in Boulder
In a historic vote, Boulder, Colorado, remunicipalized its energy provider. Charleen Fei and Ian Rinehart explain whether this is part of a broader trend and what differentiates Boulder from other American cities fighting for control over municipal utilities.
OSCAPE: Oxygen Capture and Storage – and possible Eruption
Carbon capture and storage (CCS) is sometimes touted as a promising technology for the future. But as Craig Morris points out, the technology is nothing new; it simply does not exist the way it is portrayed. Recent events in Canada and the US suggest that Germany’s lack of interest is sensible.
Germany is revolutionizing how we use energy… and the U.S. could learn a thing or two
Germany’s Energiewende is the world’s most ambitious project to get an industrialized economy on a path towards a sustainable energy system. EDF’s Peter Sopher sums up the goals and lessons for the United States.
Website update completed
The Energiewende continues to evolve, not only with new data, but also with new legislation and new topics. Last month, this website therefore received its first overhaul. Over the next few weeks, we would like to draw your attention to a few of the changes.
Net-metering not “self-reliant”
Over the past month, Craig Morris has commented on the debate surrounding net-metering (NEM) versus feed-in tariffs (FITs) several times in this blog. Today, he signs out of the discussion by pointing out that neither constitute going off-grid.
Criticism of feed-in tariffs often actually about solar
Recently, Craig Morris discussed an article that misrepresented feed-in tariffs (FITs). He also spoke with the two people quoted in the article, one of whom felt misrepresented – while the other was a prominent German spokesperson for renewables. He found that people describing policies are actually often talking about the technology effects, which the policies in question do not change.
