Rooftop solar can provide five hours of 'free' air conditioning a day. But is it green?

Rooftop solar panels and air conditioning are proving complementary technologies—solar generates peak power when summer heat and cooling demand surge together. According to Euronews, this pairing can provide up to five hours of free cooling a day. But energy analysts are questioning whether Europe's rush to install solar-powered air conditioning might actually be backfiring environmentally. The concern: as AC demand surges across the continent, the electricity infrastructure demands and overall energy footprint could offset solar's green credentials, potentially leaving the region with a larger climate impact overall.
