# Ocean waves: Overview

Wind energy, gathered and delivered by the sea

What this tile covers Energy passed from wind to the sea surface. Share of use 0% share of world energy supply (2024)

Share of world total energy supply, 2024 (latest year where noted). Denominator is the Energy Institute Statistical Review 2025 total of 592.2 EJ (physical energy content method). Flows EI omits (traditional biomass via WBA, solar and geothermal heat, food energy) are set against the same 592.2 EJ, so shares sum to slightly more than 100%. Only demonstration converters operate; output is well under 1 GWh a year (Mutriku, Spain, 210 MWh in 2024), so the share rounds to zero.
