Which of the following is a listed advantage of tidal power?

• A. Cons- expensive, very specific remote locations, salinity in basins is less
• B. Pros-Predictable, renewable, long-lasting, not harmful, local effects not global
• C. Not described
• D. It is easy to implement everywhere

Answer: (B)

When evaluating tidal power, the strongest advantage is its predictability. Tides are driven by the Moon and Sun, so their timing and magnitude follow a reliable cycle you can forecast days in advance. That makes energy output easier to plan for and integrate into the grid compared with intermittent sources like wind or solar. Tidal power is also renewable, relying on natural oceanic processes, and infrastructure built to harvest tides can last for many decades, providing a long-lived energy asset. Operational emissions are minimal, and the environmental footprint tends to be local rather than global, focusing impacts near the project site rather than affecting worldwide systems. Other statements mix in drawbacks such as high costs, site-specific constraints, or misunderstandings about salinity and deployment ease, which aren’t listed advantages.
