Oceans, which make up 71% of the Earth’s surface, are among the most precious and most significant untapped renewable resources on the planet. Ocean wave energy is enormous and has a significant role to play in the shift to renewable energy. The International Energy Agency (IEA) estimates that to attain net zero by 2050, ocean power output must increase by 33% annually.
According to José Miguel Rodrigues, a senior research scientist at SINTEF, one of the biggest research organisations in Europe, “Wave and tidal energy have the potential to be significant, reliable, and sustainable power sources.
Wave energy has the potential to produce up to 29,500 TWh annually, according to the Intergovernmental Panel on Climate Change (IPCC). That is more than the yearly electricity generated worldwide in 2018 and about ten times the annual electricity usage of Europe.
According to Rodrigues, the potential for tidal energy is believed to be between 800 and 1,200 TWh worldwide, especially in narrow waterways like inlets and surrounding islands. “[Tidal energy], which is controlled by predictable gravitational cycles rather than weather, offers a consistent supply of electricity and aids in grid balancing.
