SCIENCE

The Claim

Tidal energy is more predictable than many other renewable energy sources because it is based on a natural, regularly recurring process.

The Short Version

The evidence strongly supports this claim. Tidal energy is driven by regular gravitational cycles that can be forecast far more reliably than weather-dependent wind and solar patterns. Site-specific conditions can affect actual power output, but they do not overturn the broader predictability advantage of the tidal resource itself.

Caveats

  • The predictability advantage applies most clearly to the tidal resource and timing, not perfectly to real-world electricity output at every site.
  • Tidal energy is still intermittent: generation follows tidal cycles and may not align well with electricity demand peaks.
  • Local bathymetry, hydrodynamics, and extreme conditions can reduce forecast accuracy for plant-level output compared with the underlying tidal cycle.
