Every time you ask AI a question, generate an image, or get a personalized recommendation, something physical happens behind the screen. Massive data centers packed with servers must run nonstop to process information, using huge amounts of electricity and water to stay powered and cool. As AI becomes part of everyday life, its environmental cost is growing alongside its convenience. The challenge is not whether society should stop using AI altogether, but whether we can make this rapidly expanding technology more energy-efficient, transparent, and sustainable before its hidden footprint becomes impossible to ignore.
