Energy Flows in a Desalination Plant

From a 2006 EU-funded research project called ADU-RES, here is a Sankey diagram from one of their reports (p. 24).

It features the energy flows of an autonomous desalination unit based on renewable energy. The plant (ITC’s Dessol) where they gathered the data is on the Spanish Canary Islands. “The system is conceived for small settlements (1-1500 inhabitants), since the scale/cost factor of the required investment/land restricts the capacity of production installed to 100 m³/day”.

The figures represent annual average specific energies in kWh per m³ of desalinated water (or pumped seawater?).
