    Study Notes

    Wind and Windmills

    • Wind is caused by the uneven heating of the Earth's surface by the sun, resulting in air movement from high to low pressure areas.

    Windmills

    • The main purpose of a windmill is to convert the kinetic energy of wind into mechanical or electrical energy.

    Turbine Design

    • Small turbines are more suitable for some areas due to their low visual impact, quiet operation, and ability to generate power at lower wind speeds.

    Turbine Blades

    • The most common design for wind turbine blades is a horizontal axis with a three-blade configuration.

    Offshore Wind Plants

    • Large turbines are well-suited for offshore wind plants due to the stronger and more consistent winds available over water.

    Wind Cause

    • The primary cause of wind is the uneven heating of the Earth's surface by the sun.
