Windmills

WindmillWindmills are a common site on the Island where they are mostly used to complement solar panels or a generator for power generation. The Island has bountiful wind resources and windmills take advantage of this, generating power both day and night as long as the wind is blowing.

In general a good site for a windmill is one that provides a clean airflow of 16km/hr or more, not too close to the house because of the noise, and not too far away because of the loss of power when transmitting it to the house.

They do face a range of problems even if situated in the right place. Noise can be a major concern and isn’t constant with the turbine speeding up with the wind and then slowing down when it starts to generate power. High winds can also be a factor with some windmills needing to be taken down when severe weather approaches. Wind turbines also require more maintenance than solar panels or microhydro units due to the moving parts and exposure to the conditions.
