AI-fuelled optimism meets policy risks for European clean energy stocks

By Danilo Masoni Investors in European clean-energy producers are bracing for fresh turbulence as a months-long rally, fuelled by hopes of AI-driven power demand, collides with a resurgence of policy risk.The sector had surged on bets that data-centre expansion would finally revive electricity use after years of stagnation, echoing trends in the U.S., where renewables have shifted from a subsidies-led market to one driven by firm demand.But that narrative is under strain. Policy tremors are emerging before any clear evidence of a demand upturn, with Europe still far behind the U.S. in AI infrastructure.Amundi analyst Timothy Ho said renewed debate over carbon policy could prompt investors to revisit assumptions about valuations and earnings, while pushing Europe's energy "trilemma" back into view."You want energy to be affordable, you want security of supply and you want it to be green. Doing all three is very difficult, so policymakers have to choose which to prioritise. Right now, affordability and security are top of the agenda," said Ho.This month, Germany and others signalled openness to reform the EU carbon-trading system — a pillar of Brussels' climate strategy — while Italy moved to cut power bills as governments focus on competitiveness against the U.S. and China.The prospect of Emissions Trading System reform has already knocked carbon prices more than 20% off recent highs to their lowest since May, pressuring generators' earnings once hedges roll off. Ho said regulated network operators remain "relatively attractive" due to predictable earnings and rising grid-investment needs. But he noted some generators had re-rated on hopes of an AI-driven rise in demand despite limited "tangible evidence" so far. The International Energy Agency says European electricity demand is unlikely to return to 2021 levels before 2028, after sharp falls in 2022-2023 and only a "lacklustre" recovery thereafter. It forecasts average annual growth of 2.3% in 2025–2030, eventually matching North American rates.UNCERTAINTY MAY LAST FOR MONTHS Angelo Meda, head of equities at Banor SIM, said electricity use remained constrained, partly due to efficiency gains. AI data-centre expansion may help, but is unlikely to reverse the trend soon."The rally reflects expectations of demand growth that are unlikely to materialise ... Even EV adoption is slowing," he said, adding that ...
