Renewables stocks surge as investor inflows return and power demand outlook brightens

After two years in decline, renewable energy stocks are staging a strong comeback, driven by renewed investor inflows and a powerful shift in global electricity demand. The sector has posted its best quarterly performance since 2020, as confidence returns amid clearer U.S. policy direction and soaring energy needs from AI data centers and electrification.

Data from Lipper shows alternative energy funds attracted nearly $800 million in September, their biggest monthly inflow since April 2022, while Morningstar reports fund outflows have dropped to their lowest in over a year. The MSCI Global Alternative Energy Index rose 17% in the third quarter, doubling the broader market’s gains.

BlackRock’s Alastair Bishop said valuations had become so depressed that even negative policy news turned into a “positive catalyst,” helping investors refocus on fundamentals. Similarly, Robeco’s Roman Boner said inflows into the firm’s clean-energy strategies have resumed.

The rally has been powered by Big Tech’s AI-fueled data center boom, accelerating electrification of transport and industry, and upgrades to grid infrastructure. U.S. power consumption, flat for a decade, is now expected to surge, with solar-plus-storage emerging as the fastest way to meet demand. “Every electron counts,” Boner said.

Private equity is also reentering the space, with Global Infrastructure Partners reportedly in talks to acquire AES Corp. Analysts say renewable stocks still trade at a 40% discount to global equities, leaving room for upside as earnings momentum builds.

Despite risks from higher interest rates and political shifts, managers believe the rally could persist as short positions unwind and clean-energy earnings recover.
