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.
