IP1.20.6 Wind turbines

Wind turbines

Winds are convection currents set up in the Earth’s atmosphere

by energy from the Sun. The kinetic energy of the wind can be

used to drive wind turbines directly.

Here are some examples of wind

turbines.

Wind farm

Offshore wind farm

Rooftop wind turbine

This wind turbine is in a supermarket car park. The small-scale wind turbine is designed for urban environments.

This is a vertical-axis wind turbine. It produces less energy than a regular wind turbine and is only suitable for small-scale applications.

These wind turbines are called ‘eggbeaters’ because of their shape.
