What geographical features are ideal for tidal energy systems?

• A. Coastal regions with significant tidal movements, such as narrow bays and estuaries.
• B. Mountainous inland basins
• C. Arid desert coasts with low rainfall
• D. Open ocean far from shore

Answer: (A)

Tidal energy works best where tides drive strong, fast water through a constrained coastal channel. Narrow bays and estuaries funnel and accelerate tidal currents, increasing the amount of energy available to turbines. This geometry raises the current speed and makes energy capture more efficient, while also keeping the resource near shore for easier construction, maintenance, and grid connection. The predictable two daily high and low tides provide reliable power and better planning. Other scenarios don’t offer the same combination of strong, usable flow and practical access. Inland mountainous basins lack significant tidal movement, so their energy potential from tides is minimal. Deserts along coasts don’t inherently provide stronger tides, and open ocean far from shore presents high logistical and transmission challenges, with less favorable flow geometry for land-based or near-shore tidal systems.
