What are three costs of using wind turbines as a source of electricity?
zloy xaker [14]

There are several costs associated with using wind turbines to generate electricity.

<u>Explanation:</u>

Using wind turbines to generate electricity comes with the cost of installation of the turbines. A suitable site for installation has to be selected and windmills of the required height are installed. Cost of maintenance is another cost associated with the usage of wind turbines.

The windmills are subjected to several environmental factors like rainfall, sunlight etc. These can cause damage to the windmills. Thus a regular maintenance of the turbines is essential.

Cost of procuring appropriate land for installation of wind turbines is another associated cost. Locations apt for harnessing wind energy are limited. Moreover the windmills have to be set up across a large area to produce energy in a decent scale.
