The Guardian skriver om hur mega-dammarna inte alltid är den effektivaste energiformen - både med avseende på el-produktion och välfärd - att investera i. De nämner tex. att elproduktionen vid Inga-dammarna i Kongo-floden till övervägande del kommit gruv- och industri-företag till del medan stora delar av Kongos befolkning fortfarande står utan elektricitet. Världsbanken gör däremot satsar åter på mega-dammar. Skribenten antyder att detta kan ha institutionella orsaker då mega-projekten innebär lägre kostnader för banken - " "ratio of preparation and supervision costs to total project size" is bigger for small projects than large, centralised schemes, and so bank managers are "disincentivised" from undertaking small projects".
