1.10Summary Table: Wind Energy—key Concepts
What we have learnt
- Wind energy is generated by harnessing the kinetic energy of air.
- Local and global wind patterns significantly affect energy capture efficiency.
- Fluid mechanics principles play a crucial role in turbine function and efficiency.
Key Concepts
- -- Betz Limit
- The theoretical maximum efficiency for extracting energy from wind, capped at 59.3%.
- -- Continuity Equation
- A fundamental equation in fluid mechanics that represents the conservation of mass in airflow.
- -- Momentum Theory
- Describes how the force exerted by wind relates to the momentum change in air interacting with turbine blades.
- -- Aerodynamics
- The study of the behavior of air as it interacts with moving objects, important for turbine design.
- -- Wind Energy Conversion Systems (WECS)
- Systems designed to convert kinetic energy from wind into mechanical and then electrical energy.
