Technology

Technology drives progress in energy, from advanced solar panels and wind turbines to smart grids and AI-powered efficiency tools. It transforms how we produce, store, and use energy, making systems faster, cleaner, and more reliable. By tracking the latest innovations, we see how technology shapes the energy transition and creates solutions for a sustainable future.

What is geothermal energy? The renewable power plant hiding under your feet

The Earth is hot beneath our feet—hot enough in the right places to heat cities and generate electricity around the clock. Geothermal energy taps that underground heat, but the real story is more interesting than “find a volcano and drill.” New drilling technologies may be turning one of renewable energy’s most geographically limited resources into something much bigger.

What is nuclear fusion — and are we finally close?

Nuclear fusion is the dream machine of energy: no smokestack, no coal train, no ordinary reactor fuel rods, just light atoms squeezed so hard they snap together and spill out astonishing energy. The twist is that fusion is both real and not ready. Scientists have crossed major milestones, but a lab triumph is not the same thing as cheap electricity on your wall socket. Here’s the simple version, without the fog.
