7 Which of the following is a true statement about tidal energy? (A) It's easy to harness (B) It's more efficient than solar energy (C) It's more powerful than the energy we get from fossil fuels (D) It causes very little pollution

Tidal energy is a marvelous renewable resource that exploits the gravitational pull of the moon and sun which creates ocean tides. While it's true that it causes very little pollution, harnessing it requires significant technology and investment, especially with the need for complex infrastructure like tidal turbines and barrages. Compared to solar, tidal is not necessarily more efficient, but its reliability is a big plus since tides are predictable. When looking at tidal energy as an alternative to fossil fuels, it’s important to remember that while it does provide substantial energy, the total energy generated may not surpass what conventional fossil fuels can produce. However, the ecological impact of tidal plants is usually much lower, contributing to a cleaner environment while preserving marine life.
