📚 Quick Study Guide

  • 🌊 Tidal Energy Basics: Harnesses the kinetic energy of rising and falling tides.
  • 🔄 Tidal Range: The vertical difference between high and low tide is crucial. Larger tidal ranges mean more potential energy.
  • ⚙️ Tidal Turbines: Similar to wind turbines, but underwater, converting tidal flow into electricity.
  • 📊 Tidal Barrages: Dam-like structures across estuaries, capturing tidal water and releasing it through turbines.
  • 🌍 Environmental Impacts: Potential impacts on marine ecosystems must be carefully considered.
  • Advantages: Predictable, renewable energy source with low carbon emissions.
  • Disadvantages: High initial costs, limited suitable locations, and potential environmental effects.
  • 🧪 Key Formula: Power = $0.5 * A * \rho * v^3 * C_p$ where A = swept area, $\rho$ = density of water, v = velocity of water, and $C_p$ = coefficient of performance.
