Study Notes
Tidal Energy
- The primary source of gravitational strength for the tides is the interaction between the Earth, Moon, and Sun.
- Tidal energy is more reliable than windmills and solar energy systems, as the tides are predictable and occur twice a day, every day.
Tidal Energy and Climate Change
- The tidal energy of the earth is used to predict minor climate changes over centuries.
Renewable Energy Source
- Tidal energy is considered a renewable energy source because it harnesses the kinetic energy generated by the ocean's tides, which are infinite and sustainable.
