Yes, greenhouse gas emissions kept rising in 2025, writes Bloomberg (alternate URL here). And the pledges of various governments to lower greenhouse gases "are nowhere near where they need to be to avoid catastrophic climate change..."

But in 2025, "there were silver linings too." The world is decarbonizing faster than was expected 10 years ago and investment into the clean energy transition, including everything from wind and solar to batteries and grids, is expected to have reached a new record of $2.2 trillion globally in 2025, according to research by the Energy & Climate Intelligence Unit, a London nonprofit. "Is this enough to keep us safe? No it clearly isn't," said Gareth Redmond-King, international lead at the ECIU. "Is it remarkable progress compared to where we were headed? Clearly it is...." Global investment in clean tech far outpaced what went into polluting industries. For every $1 funding fossil fuel projects, $2 went into clean power, according to the ECIU. For China, the EU, the U.S. and India, the four largest polluters, it was $2.60.

Funds flowing into renewable power set another record in the first half of this year and were up 10% compared to the same period in 2024, to $386 billion, according to the latest available research by BloombergNEF. Solar and wind grew fast enough to meet all new electricity demand globally in the first three quarters of 2025, according to UK-based energy think tank Ember. That means renewable capacity is set to hit a new record globally this year, with Ember forecasting an 11% increase from 2024. Over the last three years, renewable capacity grew by nearly 30% on average. That puts the world within reach of the goal set at COP 28 in Dubai in 2023 to triple clean power by 2030. China is leading the charge, with the world's largest polluter expected to have delivered 66% of new solar capacity, and 69% of new wind globally this year, according to Ember. Renewables also advanced in parts of Asia, Europe and South America.

The explosive power demand from artificial intelligence is also turning the tide on green technology investment, which had soured in recent years. For the first three quarters of this year, global clean tech investment, which was dominated by funding in next-generation nuclear reactors, renewables and other solutions that help power data centers, has already surpassed all of 2024. That marks the sector's first annual increase since the 2022 peak. And despite President Trump's rollback of climate policies, the S&P's main gauge tracking clean energy is up about 50% this year, outperforming most other stock indexes and even gold. That same enthusiasm has also helped channel more capital into developing and upgrading the power grid, a backbone of the global energy transition.
The article also notes that prices per kilowatt-hour of battery capacity "fell by 8% to a record $108 this year and they're expected to decline a further 3% next year, according to BloombergNEF."

And this year the International Court of Justice "determined that countries risk being in violation of international law if they don't work toward keeping global warming to the 1.5C threshold agreed on at the Paris climate conference in 2015."

Even after its acquisition by Qualcomm, the EFF believes Arduino "isn't imposing any new bans on tinkering with or reverse engineering Arduino boards," (according to Mitch Stoltz, EFF director for competition and IP litigation). While Adafruit's managing editor Phillip Torrone had claimed to 36,000+ followers on LinkedIn that Arduino users were now "explicitly forbidden from reverse engineering," Arduino corrected him in a blog post, noting that clause in their Terms & Conditions was only for Arduino's Software-as-a-Service cloud applications. "Anything that was open, stays open."

And this week EE Times spoke to Guneet Bedi, SVP of Arduino, "who was unequivocal in saying that Arduino's governance structure had remained intact even after the acquisition." "As a business unit within Qualcomm, Arduino continues to make independent decisions on its product portfolio, with no direction imposed on where it should or should not go," Bedi said. "Everything that Arduino builds will remain open and openly available to developers, with design engineers, students and makers continuing to be the primary focus.... Developers who had mastered basic embedded workflows were now asking how to run large language models at the edge and work with artificial intelligence for vision and voice, with an open source mindset," he said. According to Bedi, this was where Qualcomm's technology became relevant. "Qualcomm's chipsets are high performance while also being very low power, which comes from their mobile and Android phone heritage. Despite being great technology, it is not easily accessible to design engineers because of cost and complexity. That made this a strong fit," he said.

The most visible outcome of this acquisition is Uno Q, which Bedi described as being comparable to a mid-tier Android phone in capability, starting at a price of $44. For Arduino, this marked a shift beyond microcontrollers without abandoning them. "At the end of the day, we have not gone away from our legacy," Bedi said. "You still have a real-time microcontroller, and you still write code the way Arduino developers are used to. What we added is compute, without forcing people to change how they work." Uno Q combines a Linux-based compute system with a real-time microcontroller from the STM32 family. "You do not need two different development environments or two different hardware platforms," Bedi added... Rather than introducing a customized operating system, Arduino chose standard Debian upstream. "We are not locking developers into anything," Bedi said. "It is standard Debian, completely open...." Pre-built models covering tasks like object detection and voice recognition run locally on the board....

While the first reference design uses Qualcomm silicon, Bedi was careful to stress that this does not define the roadmap. "There is zero dependency on Qualcomm silicon," he said. "The architecture is portable. Tomorrow, we can run this on something else." That distinction matters, particularly for developers wary of vendor lock-in following the acquisition. Uno Q does compete directly with platforms like Raspberry Pi and Nvidia Jetson, but Bedi framed the difference less in terms of raw performance and more in flexibility. "When you build on those platforms, you are locked to the board," he said. "Here, you can build a prototype, and if you like it, you can also get access to the chip and design your own hardware." With built-in storage removing the need for external components, Uno Q positions itself less as a faster board and more as a way to simplify what had become an increasingly messy development stack...

Looking a year ahead, Bedi believes developers should experience continuity rather than disruption. The familiar Arduino approach to embedded and real-time systems remains unchanged, while extending naturally into more compute-intensive applications... Taken together, Bedi's comments suggest that Arduino's post-acquisition direction is less about changing what Arduino is, and more about expanding what it can realistically be used for, without abandoning the simplicity that made it relevant in the first place.
"We want to redefine prototyping in the age of physical artificial intelligence," Bedi said...
