Boston University Study Highlights Energy Infrastructure Risks

On May 19, 2025, the Boston University Institute for Global Sustainability (IGS) published a comprehensive study in the journal Energy Research & Social Science, analyzing 662 energy infrastructure projects across 83 countries, totaling $1.358 trillion in investments. The research revealed that over 60% of these projects experienced significant cost overruns and delays. On average, projects exceeded their budgets by 40% and faced delays of nearly two years. Nuclear power plants were identified as the most problematic, with average cost overruns of 102.5%, equating to $1.56 billion more than planned, and substantial time delays.
