Sea energy is energy that is derived from the ocean, including waves, tides, salinity gradients, thermal gradients, and marine currents. This energy can be used to generate electricity, desalinate water, and pump water for irrigation. Wave energy is a form of renewable energy that can be generated from the energy of the waves in the ocean. Wave energy is a clean and renewable source of energy that can be used to generate electricity and desalinate water. Tidal energy is another form of sea energy that is generated by the rise and fall of ocean tides. Tidal energy can be used to generate electricity and pump water for irrigation. Thermal energy is energy that is generated from the difference in temperature between the surface of the ocean and the depths of the ocean. Thermal energy can be used to generate electricity, desalinate water, and pump water for irrigation.
