NEW YORK (Reuters) -Google has agreed to secure as much as 3 gigawatts of U.S. hydropower in the world’s largest corporate clean power pact for hydroelectricity, the company said on Tuesday, as Big Tech pursues the expansion of energy-hungry data centers. The deal between Google and Brookfield Asset Management includes initial 20-year power purchase agreements, totaling $3 billion, for electricity generated from two hydropower facilities in Pennsylvania. The technology industry is intensifying the hunt for massive amounts of clean electricity to power data centers needed for artificial intelligence and cloud computing, which has driven U.S. power consumption to record highs after nearly two decades of stagnation.
