The relentless rise and fall of the tides hold a hidden treasure: vast, clean energy. As the urgency to combat climate change intensifies, marine renewable energy (MRE) emerges as a game-changer. Unlike solar and wind, MRE technologies like tidal stream and wave power offer predictable energy generation, making them a reliable partner in the fight against fossil fuels. This article dives into the exciting potential of MRE, exploring its ability to deliver clean electricity while overcoming the limitations of its land-based counterparts. We'll unveil the power harnessed from the movement of oceans, showcasing how MRE can be a key player in securing a sustainable future
