Though wind energy is a low-emissions energy source, it has several practical and environmental disadvantages. Downsides of wind energy include:
The rotating blades of wind turbines can kill migratory birds and bats
Wind turbines can create noise pollution if sited close to residential areas
The movement of the blades can change surface air temperature.
Wind availability is inconsistent, therefore wind turbines do not provide a continuous supply of electricity.
Wind turbines create a ‘shadow flicker phenomenon. This is where the rotor blades cast intermittent shadows in properties close to the turbines.
Wind energy has high upfront costs, including land acquisition and surveying, site development, and the fabrication and installation of suitable wind turbines.
