Offshore Wind and Marine Energy
Offshore wind and marine energy refer to renewable energy sources harnessed from the ocean. Offshore wind utilizes turbines placed in bodies of water to capture wind energy, while marine energy involves generating power from ocean tides, waves, and currents. Both technologies offer significant potential for clean electricity production, reduce reliance on fossil fuels, and help combat climate change by tapping into abundant and sustainable energy resources found in marine environments.
