Forty million people rely on the Colorado River. The floating solar farm reduces evaporation and cools the panels.

 

Forty million people rely on the Colorado River. It is vanishing. Rising heat and relentless demand have pushed reservoirs away from a looming crisis into an active one. But a brilliant piece of engineering is now solving two massive problems at a stroke. A floating solar farm placed directly on the water does more than just generate clean energy. The panels create a massive physical canopy, blocking 90 percent of the surface evaporation that silently drains the system. The river underneath keeps the solar panels cool, pushing their efficiency higher than standard desert arrays. The panels above keep the water trapped, saving millions of gallons. Two devastating environmental challenges just solved each other.
