Define wind energy.

Energy harnessed from the kinetic energy of moving air to generate electricity.

What is a wind turbine?

A device that captures the kinetic energy of the wind and converts it into mechanical energy, which can then be used to generate electricity.

Define kinetic energy.

The energy possessed by an object due to its motion.

What is a generator?

A device that converts mechanical energy into electrical energy using magnets and coils of wire.

What are HAWTs?

Horizontal Axis Wind Turbines, the most common type, with blades rotating around a horizontal axis.

What are VAWTs?

Vertical Axis Wind Turbines, less common, with blades rotating around a vertical axis.

Define renewable energy.

Energy from sources that are naturally replenishing, such as wind, solar, and hydro.

Define intermittency in the context of wind energy.

The characteristic of wind energy being variable and not always constant, leading to fluctuating energy output.

What is noise pollution?

Excessive or disturbing noise that can negatively impact human and animal health.

What is visual pollution?

The negative aesthetic impact of human-made structures on the natural landscape.

What are the steps involved in generating electricity from wind?

Wind turns turbine blades -> rotation converts kinetic energy to mechanical energy -> generator converts mechanical energy to electrical energy -> electricity is stored.

What is the process of generating electricity from wind?

  1. Wind turns turbine blades. 2. Blades rotate a shaft connected to a generator. 3. Generator converts mechanical energy to electrical energy. 4. Electricity is stored or transmitted.

Describe how kinetic energy is converted to electricity in a wind turbine.

Wind's kinetic energy rotates turbine blades -> mechanical energy turns a generator -> generator uses magnets and coils to produce electrical energy.

What are the steps involved in storing wind energy?

Generated electricity is stored using methods like: 1. Electrical batteries. 2. Compressed air storage. 3. Hydrogen fuel cells. 4. Pumped storage.
