For years, a simple idea has shaped how people think about solar energy: solar panels last about 25 years, and then they’re done. That number shows up everywhere from manufacturer warranties to financial models, and it’s often interpreted as a hard expiration date. The implication is that once a panel or solar array hits year […]

As of late 2025, Canada is accelerating toward ambitious climate goals, including a net-zero economy by 2050 and new regulations aimed at a predominantly clean grid. Wind and solar, now among the cheapest forms of new generation, are expanding rapidly. Yet their inherent variability, producing power only when the wind blows or the sun shines, […]

During a recent business lunch, someone suggested I check out a company called Arcus Power, a software and data firm operating in the energy sector. On their website, I came across their vision: “Arcus will go beyond efficiency and reshape how energy systems communicate. It will evolve the thinking from ‘Energy Transition’ to ‘Energy Expansion’ […]

The world’s demand for energy is growing at a pace we’ve never seen before. Rising populations, expanding industries, and the electrification of everything, from cars to heating systems, are fueling the need for more reliable power generation. At the same time, the pressure to deliver large-scale infrastructure quickly, efficiently, and cost-effectively has never been greater. […]
