What is a limitation of tidal energy technology?

• A. It is still in early development stages and not widely implemented on a commercial scale.
• B. It is too cheap to be viable
• C. It produces large emissions
• D. It requires rare earth metals

Answer: (A)

Tidal energy is limited mainly by how mature the technology is and how broadly it can be deployed. Compared with other renewables, tidal systems are still largely in development, with relatively few full-scale commercial projects. The biggest hurdles are high upfront costs, complex and expensive marine engineering, harsh operating conditions that drive maintenance needs, and the fact that suitable sites with strong, predictable tidal flows are geographically limited. All of these factors keep large-scale, cost-effective deployment from becoming widespread. That’s why the statement about it being too cheap to be viable isn’t right—tidal energy is not considered financially ready for broad commercial use. It also isn’t accurate to say it produces large emissions—its operating emissions are very low. And while some components may use materials that involve rare earth magnets, that isn’t the fundamental barrier to adoption. The core limitation is the current stage of development and limited commercial scale.
