Summary of "Tidal Power 101"
Scientific Concepts and Discoveries
- Tidal Power: A form of hydro power that converts the energy from the natural rise and fall of tides into electricity.
- Causes of Tides: Tides are influenced by the gravitational forces of the moon and the sun, as well as the Earth's rotation.
- Tidal Energy Technologies:
- Tidal Barrages: Most efficient form of tidal energy; these are dams that utilize the potential energy from the height difference between high and low tides to generate electricity.
- Tidal Fences: Turbines that function like giant turnstiles, converting tidal energy into electricity.
- Tidal Turbines: Similar to wind turbines but located underwater; they generate electricity when tidal currents turn the turbines connected to a generator.
- Energy Density: Ocean currents generate more energy than air currents due to the higher density of water (832 times denser than air), which applies greater force on turbines.
- Predictability: Tidal energy is predictable, making it advantageous for electrical grid management compared to other renewable sources.
Challenges
- Site Requirements: Specific geographical conditions are necessary for Tidal Power plants, limiting where they can be installed.
- Demand Mismatch: Tidal cycles do not always align with daily electricity consumption patterns, affecting capacity to meet demand.
