- Its reference dam uses a 135 m water drop and 87% efficiency; the page names CEA, Orano, RTE and ADEME among its sources.
Field notes
The interface lets visitors enter an activity directly or specify power multiplied by duration, with energy units ranging from watt-hours to calories. Its comparison material puts hydroelectricity beside uranium, wind, solar power and cycling, and names sources including CEA, Orano, RTE, ADEME and PVGIS. The illustrative dam calculation uses a 135-metre head and 87% efficiency, so its water equivalents are tied to an explicit reference case.
