Eco Wave, ‘Magic Ball’ Among Time’s Best 100 Inventions 2025

EEPower tries to inform our readers of the latest and best innovations in power electronics and electrification, and it seems that Time magazine agrees with us. EEPower had already covered four of its top choices in its 2025 Best 100 Inventions. In this article, take a look at how well we did and what other inventions Time found. - Karen Hanson.

EEPower covered them first: Voltpost, EcoWave, Candela, and Heimdall.

Kawasaki Uses Hydrogen to Create Serious ‘Horse’-Power

Sometimes an article stands out because of its images (and videos). And this article is exactly that. Who could resist this futuristic hydrogen-powered robotic horse? Will a robotic knight be the next step for Kawasaki? - Karen Hanson.

Tech Giants Race To Grab Power for Data Centers

It was difficult to choose just one data center article—there were so many! But this article captures the “how” and “why” data centers became the hottest topic in 2025. AI and cloud developers like Google, Meta, Amazon, and OpenAI desperately need power, and they are leaving no energy source untapped. - Karen Hanson.

ABB Upgrades NASA Wind Tunnel With Powerful Motor Drive

I have always geeked out on aerospace technology. One of my favorite places in the world to spend a day is the National Museum of the US Air Force at Wright-Patterson Air Force Base in Dayton, Ohio. So this article on ABB’s efforts to modernize NASA's wind tunnel drive was an easy favorite for me.

The numbers are hard to fathom: a 101 MW variable-speed drive to control a 135,000-horsepower synchronous motor to generate air velocities greater than Mach 1. If anyone can arrange for me to get an all-expenses-paid trip for a tour and demonstration of the wind tunnel, my email is [email protected]! - Dale Wilson.

Giving A Second Life to Aging Cables: Understanding Cable Rejuvenation

I spent a couple of decades working as an electrical engineer, primarily on integrated circuits, not transmission and distribution. So, I found this contributed article on how to refresh old underground power cables absolutely fascinating. An innovative, relatively low-cost solution to an expensive problem is a reminder that the best engineering solutions don’t always have to be high-tech or even use integrated circuits. - Dale Wilson.

Eversource Leverages MATLAB for Probabilistic Load Flow to Advance Grid Planning Efforts

During my many years as an engineering student, MATLAB was my favorite software program. So, for this article, I was happy to get a chance to chat with tech experts at MathWorks and Eversource Energy to learn how they were applying unique simulation solutions to sticky grid problems.

The challenge is rather staggering. Their goal is to simulate complex grids that encompass many stations, each having a distribution network with tens of thousands of nodes and branches and hundreds of distribution transformers. Oh yeah, and they want to simulate how it operates in an 8760 world (24 hours a day, 365 days a year) with different weather, different load conditions, and more. I learned a lot about how they were using advanced simulation and data visualization for their grid modernization design efforts and to make improved investment decisions. - Dale Wilson.

Next-Gen Solar Cells Break Indoor Efficiency Records

I don’t mean to brag, but when I won the 6th grade science fair with my project “A Solar Powered House of the Future.” Suffice to say, my interest in solar energy started early. EEPower has published a lot of research news stories in 2025, and this article exemplifies the dynamic state of solar cell research happening these days.

The article explores how University College London (UCL) researchers achieved a record 37.6% efficiency for indoor perovskite solar cells using a "triple passivation" method to fix defects. Optimized for LED light, these cells offer high stability and power. This breakthrough enables battery-free IoT devices and sensors, providing a sustainable, maintenance-free solution for powering smart electronics using only ambient indoor light. - Jeff Child.

Power Sector Urgently Needs More Engineers With Diverse Skills

As the premiere digital publication for power and energy engineers, EEPower offers the best content to help our readers do their jobs. This article, by EEPower’s own Karen Hanson, takes a look at just how in demand power engineering experts like you will be in the coming years. The article dissects research from Kearney and IEEE Power & Energy that shows how power engineers are crucial as energy demand grows and the industry diversifies.

As the article points out, highly skilled workers must be able to design and manage the energy needs of data centers, distributed resources, EVs, and renewable energy. By 2030, the number of power engineers needed could double to up to 1.5 million jobs. The problem is, qualified engineers may be difficult to find, especially those trained in renewable fields and digital technologies. - Jeff Child.

GaN-Powered Reference Kit Targets Solar Race Cars and EVs

Gallium Nitride (GaN) ranks as one of the most important technologies for today’s power system designs. This story discusses a hands-on tool to get started with GaN designs today: a reference design kit integrating its high-efficiency PowiGaN-based InnoSwitch3-AQ IC. 

Beyond that, the kit was announced to coincide with the 2025 Bridgestone World Solar Challenge, showcasing automotive GaN adoption and its use in student-led vehicle electrification. The racecar environment provides a unique proving ground for technologies that could transition to mainstream electric mobility or off-grid renewables. - Jeff Child.
