Today, in our environmental science lecture, we're discussing renewable energy sources. While solar and wind power are popular, there's growing interest in tidal energy. Unlike solar panels, which depend on sunlight, tidal turbines work consistently because tides are predictable. However, a major challenge is the high cost of underwater installation and maintenance. Additionally, tidal energy can affect marine ecosystems, particularly fish migration patterns. Currently, only a few countries, including the UK and South Korea, have operational tidal power plants. Despite these limitations, researchers believe that with technological advances, tidal energy could supply up to 10% of global electricity demand by 2050.
