The Philippine government has formally turned over operations of the Caliraya–Botocan–Kalayaan (CBK) Hydroelectric Power Plant complex in Laguna to the Aboitiz-led Thunder Consortium, completing one of the country’s most consequential power sector privatizations at a time when grid flexibility is becoming just as important as sheer generation capacity. The Thunder … [continued]
ChatGPT generated map showing China’s shift from coal-based aluminum in the north and northwest toward hydropower in the southwest, with growing secondary aluminum recycling nationwide
China’s aluminum manufacturing CO2 emissions likely peaked in 2024, not because production collapsed or because a single policy suddenly bit, but because the structure of where aluminum is made and how it is made changed in ways that compound over time. Aluminum is a useful material to examine because it … [continued]
A new, compact pumped hydro energy storage system uses lower elevations and sloping hills, avoiding the cost and environmental impacts of mountain-based storage systems (screenshot, courtesy of RheEnergise).

Google Gemini generated this infographic illustrating a comparison between China and India's shift towards "electrostates" and the West's reliance on being "petrostates."
The idea that heavy freight would be the last redoubt of diesel has been repeated for decades, often with confidence and rarely with evidence. In December 2025, that idea finally collapsed. Battery-electric heavy duty trucks crossed 50% of new sales in China, a segment that had long been treated as … [continued]
The proposed Goldendale Energy Storage Project in Washington State is one step closer to adding 1.2 gigawatts of pumped hydropower storage to the nation's renewable energy profile (cropped, courtesy of Rye Development via email).

Google Gemini generated this infographic comparing the supply chains and applications of imported green feedstocks and green hydrogen.
Europe’s gas crisis in 2022 is often described as a supply shock driven by geopolitics, but that framing misses the core lesson. The crisis was not caused by import dependence in general, nor by shortages of industrial feedstocks. It was caused by reliance on an imported energy carrier that sat … [continued]
Hydropower operators can save money on turbine repairs and maintenance, and add revenue by adding battery-type energy storage systems (cropped, courtesy of PNNL via email to CleanTechnica).
When US President Donald Trump declared an “energy emergency” on January 20 of last year, he tapped the nation’s hydropower industry for preferential treatment alongside coal and other fossil fuels. And so, it is no surprise to see the US Department of Energy issuing a new report that outlines the … [continued]
The Spanish government is going down the route a bit that President Biden and Democrats went down. It is subsidizing the manufacturing of various renewable energy and energy efficiency technologies, to the tune of €355 million. “The new call for funding proposals is inviting equipment makers from the following categories … [continued]
ChatGPT generated: A solemn panoramic scene of the American flag at half-mast before the NREL building, marking the symbolic end of an era in U.S. renewable-energy leadership
The erasure of the word “Renewable” from the National Renewable Energy Laboratory marks the end—or hopefully just an interruption—of a long and consequential chapter in energy history. Renaming it as the National Laboratory of the Rockies doesn’t change the buildings in Golden or the servers in ESIF or the unfinished … [continued]
FERC is under pressure from the energy secretary to eliminate a policy that gives native people control over energy projects on their land.
