Study Notes
Overview of Renewable Energy Resources
- Renewable resources are natural resources that regenerate at a faster rate than consumption.
Windmills
- Historically utilized to crush grains and produce flour.
- Function: Operates by wind moving the blades, which transfer kinetic energy to the internal components.
- Characteristics: Shorter than modern wind turbines, more blades, and feature openings in the blades.
Watermills
- Also used for grinding grains to produce flour.
- Function: Operates by water moving the blades, similarly transferring kinetic energy to internal parts.
Importance of Mills
- Essential for processing grains into flour.
Advantages of Renewable Energy
- Both wind and watermills utilize renewable energy sources.
- Generally low operational costs.
Disadvantages of Renewable Energy
- Watermills may become ineffective if water supply diminishes.
- Windmills are reliant on consistent wind; insufficient wind stops functionality.
Modern Wind Turbines
- Currently employed to generate electricity.
- Characteristics: Taller than traditional windmills, fewer blades, and without openings in the blades.
- Similarity to windmills: Both types depend on kinetic energy from wind for operation.
