The École nationale supérieure de l'énergie, l'eau et l'environnement (Ense3) (National Graduate School of Energy, Water, and the Environment) is one of the engineering schools[2] of the Institut National Polytechnique de Grenoble.

As a grande école, students are admitted through a nationwide competitive examination.

ENSHM was later founded in 1929 to satisfy the demands of the local industries in Grenoble for graduating engineers in fluid mechanics and hydroelectricity.

The school provides engineering training in the fields of energy (production, transport, distribution and management, and information processing), water (hydraulics, hydrology, civil engineering) and environment (renewable energies, energy efficiency, geotechnical, soil pollution, and environmental water quality).

Evidence of earlier degrees obtained from other universities could also serve as a foundation for admission.
