I’ve been watching the green tech craze for years, and now they’re pushing solutions for small urban spaces as if they’re a magic bullet. How exactly do these innovations perform when the promised efficiency and cost savings are measured against reality? Is the small-scale photovoltaic setup on a tiny balcony or the compact vertical garden really more than just a feel-good thermostat fix? I’m skeptical about whether these systems can overcome the limitations of space, scale, and ultimately, the hidden expenses. Has anyone here had direct experience with these so-called breakthroughs, or are we just trading one set of overhyped promises for another?
