Wind turbines harness the kinetic energy of the wind to generate electricity.

China is the world's largest producer of wind energy, accounting for over a third of global capacity.

The swept area is the area covered by the rotating blades of a wind turbine.

The Betz limit is the theoretical maximum efficiency of a wind turbine, which is approximately 59.3%.

The generator is the component of a wind turbine that converts the mechanical energy of the rotating rotor into electrical energy.

Wind energy is a sustainable source of energy because it does not produce greenhouse gases or other pollutants.

Wind energy is intermittent, meaning that it is not always available when it is needed.

Energy storage is the process of storing excess wind energy for later use.

Visual pollution is the term used to describe the negative impact of wind turbines on the landscape.

Wind turbine noise is the term used to describe the noise produced by wind turbines.

Habitat loss is the primary environmental impact associated with wind energy, as wind turbines can kill birds and bats.

Environmental impact assessment is the process of assessing the environmental impact of wind energy projects.

Decommissioning is the process of decommissioning wind turbines at the end of their lifespan.

The primary challenge associated with decommissioning wind turbines is cost.

The future outlook for wind energy is growing, as it is a cost-effective and sustainable source of energy.
