Question

What are the advantages of harnessing tidal energy?

Answer 1

The main advantages of harnessing tidal energy include:

1. High Predictability: Unlike wind or solar power, tides are powered by the gravitational pull of the moon and sun, making tidal patterns extremely predictable centuries in advance.
2. Massive Energy Density: Water is approximately 800 times denser than air, so tidal turbines can create substantially more electricity than wind turbines of the same size, even at modest water speeds.
3. Long Lifespan and Durability: Long Lifespan and Durability: Tidal power plants and barrages are extremely durable structures that can function efficiently for 60 to 100 years, much outlasting solar panels and wind turbines.
4. No Fuel Costs or Emission: No Fuel Costs or Emissions: Once the infrastructure is created, the energy source is absolutely free, and the operational phase emits no greenhouse gases or air pollution.
5. Minimal Visual Impact: Underwater tidal stream turbines are totally submerged, resulting in minimal visible alterations to the scenery and no noise pollution above the water.
