As centrais hidroeléctricas producen arredor de unha quinta parte da enerxía do mundo, sen gasto de materias primas e con alta eficiencia. As hidroeléctricas máis grandes son as centrais de enerxía máis grandes do mundo, producindo máis do triple de enerxía que as maiores nucleares e térmicas. Sen embargo, acarrea un impacto ambiental moi elevado.

No 2014, a presa máis grande do mundo -Tres Gargantas (China)- xenerou o equivalente a un 25% da producción enerxética española sen necesidade de recurrir a combustibles fósiles. O proxecto, cun orzamento de 25.000 millóns de euros, creou unha gran cantidade de postos de traballo na área.
Sen embargo, 1.3 millóns de persoas tiveron que deixar atrás a súas casas debido ás inundacións provocadas pola presa. Millóns de animais viron os seus cursos migratorios e hábitats modificados. Zonas de ampla riqueza cultural e arqueolóxica foron anegadas para sempre.
