Marine renewable energy has transitioned from experimental concept to operational reality, with wave and tidal technologies now generating electricity at commercial pilot sites across multiple continents. The sector achieved a significant milestone when the US Department of Energy’s 2026 assessments confirmed that waves and tidal currents could theoretically generate approximately 1,420 TWh of electricity annually from American coastlines alone, representing a substantial untapped resource that rivals established renewable sectors in scale.
This transformation reflects more than improved turbine designs or better wave energy …
