Deep beneath our feet lies one of nature’s greatest untapped wonders: the Earth’s relentless, molten heat engine. For over 10,000 years, Indigenous peoples around the world have revered hot springs as sacred lifelines, using them to heal, cook, and warm entire communities. What began as cultural wisdom slowly evolved into engineering ambition. In 1904, in […]

In the sweltering heat of a Havana summer afternoon, lights flicker and die across entire neighborhoods, fans grind to a halt, and refrigerators fall silent. Families light candles or cluster around battery-powered radios as rolling blackouts stretch from hours into days, weeks, and beyond. It would be easy to assume this is a scene from […]

Last week I had the privilege of receiving an invitation from Dr. Jason Donev to spend two days at the University of Calgary attending a series of lectures by Dr. Jeremy Whitlock. The lectures covered the history of nuclear science in Canada, the development of Small Modular Reactors (SMRs), nuclear non-proliferation, and “the exciting road […]

Non-Wires Alternatives (NWAs), also called non-wires solutions or non-transmission alternatives, are exactly what the name implies: smarter ways to fix grid problems without always building expensive new wires, poles, transformers, or substations. By targeting peak demand with demand response, energy efficiency, distributed generation, battery storage, and smart tech, NWAs reduce load, ease congestion, and resolve […]

Canada is poised to lead the global shift to clean energy, with abundant renewable resources, ambitious net-zero targets, and a growing pipeline of wind, solar, and storage projects. Yet, despite strong developer interest and supportive policies, the pace of deployment often falls short. One of the most significant barriers lies not in technology or financing, […]
