Wave Energy

Wave energy harnesses ocean waves to generate electricity using technologies like oscillating water columns and point absorbers. It offers a sustainable, reliable energy source but faces challenges such as high costs, environmental impacts, and technological development for large-scale use.

Current & Tidal Energy

Current energy harnesses steady ocean currents using underwater turbines, offering a reliable energy source but facing challenges with deep-sea deployment and ecological impacts. Tidal energy captures power from tidal movements through barrages or underwater turbines, providing a predictable source of energy but requiring specific coastal conditions and potentially affecting marine ecosystems.

Offshore Wind

Offshore wind energy involves generating electricity from wind turbines located at sea, typically in shallow waters where winds are stronger and more consistent. These turbines capture wind energy and convert it into electricity, which is transmitted to the grid. Offshore wind energy is a promising renewable source with the potential for large-scale power generation, but it requires significant infrastructure and presents challenges related to installation, maintenance, and environmental impacts.
