Non-Conventional Source of Energy Energy from the Sea

The video discusses the depletion of Earth's natural energy resources and explores alternative energy sources from the ocean. It covers wave energy, which uses the motion of waves to generate electricity, tidal energy that harnesses the gravitational pull of the moon, and ocean thermal energy conversion (OTEC) that utilizes temperature differences in ocean water. Each method's process and limitations are explained, highlighting the potential of the sea to provide eco-friendly energy solutions.
